Adding another to the challenges already
mentioned
I just read “Challenges for the 21st Century” in my May
issue of Resource.
I noted water and energy were a common theme with
emphasis on improved efficiency in purifying sea and polluted water. There is certainly a need to meet this type of
challenge, especially in areas of the planet where precipitation is insufficient to sustain humanity and agriculture;
but ...
I was surprised not to see mention of climate management as a challenge to be worked on during the next 100
years. There is already talk about global warming and suggestions to limit carbon dioxide in the atmosphere to control temperature. I think there will also be efforts to
manage precipitation. Members of ASABE have long been
involved with drainage, hydrology, irrigation, and climate
records, so they logically will be involved with and work
toward climates management, especially working toward
managing precipitation.
Whether it is climate management or the challenge
items mentioned in Resource, there will be difficulty bringing the challenges into fruition without the citizens of the
world forcing their governments and politicians to provide
stable governments in all countries.

This is an “under construction” Web site where
researchers working on an innovative type of organic farming are listed, and they may contribute to its content through
a “wiki” system (like wikipedia.org). It also includes a

The Future of
Intelligent Agriculture
Wireless Site-specific Irrigation
Yunseop (James) Kim, Robert G. Evans, and William M. Iversen
H
aving a cup of green tea, a farmer watches a
computer monitor at home checking his irrigation
system. He is taking stock of soil moisture conditions across his field and keeping a watchful eye on
his irrigation machine. The monitor displays the location of
the machine, as it moves across the field, on an irrigation map
that shows how much water is applied to each of several different zones. An hour later, a rain shower passes over the field,
and the software automatically adjusts the amount of irrigation water being applied.
The farmer is using a wireless site-specific irrigation system with a distributed wireless sensor network. The system
allows growers to remotely access field conditions and an irrigation operation at the home or office via wireless radio communication, directing individual sprinklers on how much
water to apply and where.
Water management
Water is a major factor for plant growth. Traditional uniform water applications ignore field variations that cause
varying crop yield and quality across most fields. Excessive
application leads to drainage and disease problems, whereas
under application reduces yields. The development of an efficient water management system, therefore, is a major concern
around the globe to improve water-use efficiency and support
a sustainable environment. The challenge is to develop a system that accurately and inexpensively senses field variability
and controls variable-rate irrigation according to the spatial
variability. To meet the challenge, researchers at the USDAARS research laboratory in Sidney, Montana have been working since 2004 on developing a wireless in-field sensor-based
irrigation system supporting site-specific irrigation management using low cost wireless radios.
Researchers developed an automated closed-loop irrigation system that requires three major components: machine
conversion, navigation, and mission planning. A linear-move
irrigation machine was converted from a conventional
mechanical and hydraulic system to an electronically-controllable system for individual sprinkler control. The navigation
of the irrigation machine was continuously reported every
second by a differential global positioning system (GPS)

receiver mounted on the main cart. Mission planning was
updated according to information of the cart location and field
conditions monitored by sensors distributed across the field.
The system consisted of in-field sensor stations distributed across the field, an irrigation control station, and a base
station (Fig. 1). The in-field sensor stations monitor the field
conditions of soil moisture, soil temperature, and air temperature, whereas a nearby weather station monitors micrometeorological information on the field, i.e., air temperature,
relative humidity, precipitation, wind speed, wind direction,
and solar radiation. All in-field sensory data are wirelessly
transmitted to the base station. The base station processes the
in-field sensory data through a user-friendly decision-making
program and sends control commands to the irrigation control
station. The irrigation control station updates and sends the
location of the irrigation machine from a differential GPS to
the base station for real-time monitoring and control. Based
on sprinkler head GPS locations, the base station feeds control signals back to the irrigation control station to site-specifically operate each individual sprinkler group to apply a
specified depth of water.
The experimental field was located 700 m (0.4 mile)
from the base station at Sidney, Mont., and the data transfer
rate required less than 1 KB per cycle in both transmitting and
receiving due to a short text string of sensory data.

The Map vs. the Compass
Navigating Modern Career Uncertainty

M
ore so than many other
engineering specialties,
the agricultural engineer
is familiar with the land.
From soil and water conservation
efforts to the design and manufacture of
the implements necessary to harvest
crops, agricultural engineers may be
regarded as the stewards of the land
upon which we all depend. Careers,
much like the land, require careful management and equally diligent stewardship, as the maps used by many
engineers in the past to chart a successful course become less certain, more
ambiguous, and fraught with unfamiliar
terrain. Increasingly, an engineer will
need to use a compass to navigate
career terrain that can shift as quickly
and as unpredictably as the sands of the
Sahara. While the compass is more traditionally associated with organizations
such as the Boy Scouts or sports such as
orienteering, a working knowledge of it
can be the difference between being
“lost” when familiar career terrain
changes, and of developing a “sense”
for where you’re at, where you’ve been,
and, perhaps most importantly, for how
to move forward in your career, regardless of circumstances.
This is not your father’s
engineering career
In the past, the terms “engineering
career” and “uncertainty” were rarely
encountered in the same sentence.
Engineers, after all, have been among
the primary drivers of industrial
progress, the critical link between perceived social needs and the commercial
applications that satisfy those needs.

RESOURCE
Although the knowledge, skills, abilities, and talents that many engineers
possess are not likely to diminish in
importance anytime soon, how those
attributes map to contemporary careers
is undergoing a fundamental change.
Ever since J.B. Davidson founded
the first agricultural engineering program at Iowa State University in 1905,
many fundamental components of the
curriculum remain. Classroom instruction, laboratory experiences, and
internships have formed a solid foundation upon which to carry the knowledge
and skills acquired in school forward to
the world of work. In essence, an engineer, upon graduation, has developed a
fairly standard “map” of what, at the
time, is considered necessary to be a
successful practitioner of the craft. The
greater the breadth or depth of the
“map” (either spanning more territory
or providing greater detail and clarity of
the various specialties one might expect
to encounter, or both), the more successful the engineer might expect to
become. Or so he or she thought.
“The map is not the terrain”
Despite the fact that maps have
existed for centuries, they also suffer
from a few inherent flaws that are difficult to correct. Once printed, they
quickly become obsolete as the terrain
they attempt to describe changes. They
also suffer from distortion, as our
planet is spherical, not flat. Without
careful stewardship, many of the deficiencies from which maps suffer can
impair and limit the career prospects of
the modern engineer. “The map is not
the terrain,” attributed to Eric Von
Clauswitz, a 19th century military
strategist, rings true today. Reality has a
nasty way of rendering even the best
map, and the associated career terrain
an engineer might reasonably expect to
encounter, obsolete in a hurry.
Why are career maps developed
in college becoming obsolete
more quickly?
The very nature of what constitutes
employment in modern society has,
within a generation, undergone a rather
dramatic (and for many, unsettling)
shift. Despite the indispensable nature
of their work, engineers have not been
exempt from the turbulence and uncertainty accompanying the modern career
environment. To better understand
what’s going on, consider the relationship between an engineer and the engineer’s employer. Prior to the 1970s, in
what amounted to a social contract, an
employer generally provided benefits
such as lifetime (or at least long-term)
employment, generous pension plans,
and fully paid health care to employees.
The arrangement assumed that both
parties, through economic peaks and
valleys alike, would stick together. An
engineer could look forward to mapping career progress against personal
and organizational benchmarks that
were time-tested, reliable, and fairly
static. The following decades, and the
economic tumult that have accompanied them, have transformed the relationship of engineer and employer into
a more transaction-oriented contract
based upon an exchange of benefits
between the two. The net effect of this
is that job security and its trappings will
fade in importance and be replaced
with
marketability
of
skills.
Additionally, navigation of foreign
career terrain will necessitate more frequent replotting of an engineer’s career
map. In short, the agricultural engineer will simultaneously need to update his
or her career map while
navigating unfamiliar terrain with an instrument that has traditionally found less use – the compass.

ENGINEERS HAVE NOT BEEN EXEMPT
FROM THE TURBULENCE ACCOMPANYING
THE MODERN CAREER ENVIRONMENT.
How does an engineer proceed?
Think of the activities that prepare
an agricultural engineer to do the job –
and do it well. In the past, with a more
static and predictable economy, and
correspondingly stable organizational
environment, a map was quite sufficient. That is, a map was very useful
when parameters such as measuring
individual progress and results, within a
well-defined position in an organizational hierarchy, were fairly constant.
When agricultural engineers were able
to rely more upon established practices,
and incrementally improve upon them,
charting a course with a compass was
not really necessary. However, in our
current economy, with daily occurrences of downsizings, layoffs, and offshorings, using a map to navigate such
events can be as dated as using a slide
rule to make calculations. The current
employment
environment
often
requires improvisation or the ability to
flexibly treat rules many take for
granted as immutable. Policies and procedures developed years ago won’t do
an engineer much good if he or she isn’t
willing to question one’s validity and
applicability in the modern world – to
use previous experience and knowledge
to demonstrate why a certain assumption may no longer be true. The need to
constantly update one’s personal “tool
kit” of experience and knowledge will
increase as an engineer will be valued
more on the basis of expertise and less
upon rank, position, or tenure within a
enable the engineer to learn from others, to encourage dialogue for the purpose of problem solving (as opposed to
defending a position, which may be fallacious), to better experience a problem
from the vantage point of others, and to
facilitate movement towards the most
appropriate solution. Using a compass
is more appropriate for sensemaking
amid uncertainty as it serves to guide
our actions when maps, and their presumed certainty, fail to deliver.
Career navigation with the compass is rarely easy or mundane
The uncharted terrain can be
downright hostile and foreboding as it
undoubtedly was for those explorers
hoping to find a more direct route to the
Far East in centuries past. Lewis and
Clark took great personal risks some
200 years ago to better chart a vast,
untamed wilderness – a wilderness,
nevertheless, with great promise – a
wilderness many proudly call the
United States. Each of these individuals
courageously charted a bold new path
yet didn’t forget the “lessons learned”
from their experiences. It was their
knowledge that allowed others to gradually settle the previously uncharted
terrain, to incorporate its features, landmarks, topography, and climate into the
appropriate map. The engineer who
pushes forward with a compass can
realize rewards far exceeding those who
continue to rely on the familiarity of a
map and can also help others settle similarly uncharted and unfamiliar career
terrain. Unique and unusual career
opportunities, combining elements of
domains, etc.) while perhaps unorthodox to those who prefer maps, are possible for those who are prepared for the
potential challenges. Projects incorporating previously overlooked specialties and
knowledge can enable a company to
develop a new product, offer an innovative
service, or uncover a previously unknown
competency – all making the employer
and engineer (and the engineering profession) more valuable as a direct result.
Don’t think for an instant ...
... that the profession of engineering in general, and agricultural engineering in particular, is taking on the
character of a dated map. Engineers are
simply too valuable in terms of the
knowledge, skills, abilities, and talents
they “bring to the table,” and the occupation is likely to increase in importance
as the challenges confronting society
grow more complex. However, the standard map, linking the knowledge
acquired in school to the tasks traditionally associated with the profession, isn’t
as accurate or as useful as in years gone
by. The successful engineer will more
and more frequently be the one capable
of navigating, when appropriate with a
compass, and able to accurately convey
the new terrain, in all of its detail, to
both current and subsequent employers
and other engineers as well.
After all, it’s your career – make
the most of it.

The Mechanizing Miracle of
Tomato Harvesting
Bruce Hartsough
The operator in the patent drawing
for a tomato harvester (top)
appears to be nodding off, as well
he might. In contrast to the many
activities carried out in manual
harvesting, the harvester operator’s
primary duty appears to be steering. In reality, life was somewhat
more complicated for the operator,
and much other human assistance
was required for sorting good ripe
fruit from other material, as shown
in the photo (middle) of the first
UC-Blackwelder prototype. The
machine was complex and multifunctional, as attested to by the
11 sheets of drawings and
47 claims in the patent description.
As with most “new” equipment, the
harvester borrowed many concepts
from other devices: in this case,
harvesters for crops that could
withstand more violent treatment
than could the genteel tomato.

T
ake a valuable, hand-harvested crop, add a legislated labor shortage, throw in a bit of engineering
ingenuity and – voilà! – you get an instant solution.
In the case of processing tomatoes, it might appear
that way at first glance. In 1964, Congress ended the Bracero
program that had brought laborers from Mexico to the United
States since 1942. Prior to 1964, tomatoes destined for
processing had been picked by hand. Five years later, essentially all were harvested by machine. But the quick adoption
doesn’t reveal the true story – one that involved 20 years of
effort by plant breeders and more than a decade of
engineering. And development of the tomato harvester
demonstrated the need for collaboration between biologists
and engineers to solve problems related to biological systems.
Careful, careful ...
Tomato harvesting was one of the first cases of picking a
relatively fragile crop by machine, in contrast to those such as
grain or cotton. Agricultural engineer and ASABE member
Bill Stout and horticulturist Stan Ries at Michigan State
University explains: “For many years, mechanical harvesting
of tomatoes was considered impossible because of the wide
variation in the date of maturity of fruit on the plant and the
random location of ripe fruit. The fact that ripe tomatoes are
soft and easily broken makes the problem more complex.”
In 1942, Jack Hanna, Vegetable Crops at the University of
California (UC), Davis, began
to search for and then breed
tomato varieties that could be
harvested in one pass and
withstand mechanical handling. He tested 2,000 lines
before releasing the VF-145 in
1962; this variety dominated
the industry for more than a
decade.
In 1949, Hanna began collaborating with Coby Lorenzen
in agricultural engineering at UC Davis to develop a harvester
on a shoestring budget. When the labor shortage appeared
imminent, industry increased their support in California and
elsewhere. Stout and Ries initiated an effort in the late 1950s
and tested three iterations of harvesters. By 1962, several
different machines were being tested and/or introduced. New
tomato varieties were developed as well. The high level of
cooperation between the various breeders and engineers was
remarkable.
centrifugal force. They demonstrated an experimental
harvester to growers in 1955 but elicited little interest. Steven
Sluka, an engineer who escaped from Hungary after the
Communist takeover, joined the project in the late 1950s and
designed an effective separator that employed a set of “straw
walkers” somewhat similar to those on a grain combine. The
harvester was tested in 1959 on the Heringer farm near
Clarksburg, Calif. The Heringers were so impressed that they
convinced Blackwelder Manufacturing in Rio Vista, Calif. to
commercialize the design. Patents were granted to Lorenzen,
Sluka, and Fred Hill, an engineer at Blackwelder. Although
several harvester manufacturers eventually captured big
shares of the market, UC-Blackwelder machines dominated in
the early years.
Designs kept improving, and productivity increased by an
order of magnitude. Key innovations included bulk handling
and transportation of tomatoes, an oscillating rotary shaker to
separate fruit from the vine, and electronic sorting to cull out
green fruit.
You say “to-may-to,” I say “to-mah-to”
Training of growers by UC Cooperative Extension personnel was critical to the acceptance of mechanical harvesting
because the transition required new varieties, higher planting
densities, and different irrigation and fertilization techniques
to obtain uniform maturity and high yields.
HARVESTING INVOLVES MANY FUNCTIONS,
SUCH AS CUTTING AND LIFTING THE
VINES, BUT SEPARATING THE FRUIT IS
THE MOST CRUCIAL.
A complicated harvest
Harvesting involves many functions, such as cutting and
lifting the vines, but separating the fruit is the most crucial.
Lorenzen and Hanna experimented with 15 separation
approaches over a decade: shaking, combing, clawing, and
Mechanical harvesting was controversial because it
seemingly displaced human labor; but by reducing harvesting
costs by close to half, it eliminated an economic constraint on
the U.S. processing tomato industry. This resulted in large
increases in both tomato acreage and tonnage. These
increases provided additional employment in planting,
irrigating, and tending the vines, as well as in transporting and
processing the crop – jobs which offset the harvesting stooplabor displaced.
California was the initial beneficiary due to early
development and adoption of the new varieties and the state’s
dry summers that coincided with harvest. Mechanical
harvesting is now common in most regions of the world where
processing tomatoes are grown.

his article completes a 10-part series on energy. The
first installment examined energy challenges and
opportunities facing the United States. Follow-up
articles investigated energy efficiency and renewable
technologies in key areas – including buildings, industry, transportation, and a number of renewable energy technologies –
biomass and biorefineries, wind, solar, geothermal, and
hydrogen.
Great strides have been made in the advancement of
many of these technologies. Some – such as compact fluorescent lighting, wind power, and hybrid vehicles – are now commercially viable. Others, like photovoltaics, although seen as
socially and environmentally attractive, are still often limited
by costs and technological barriers to niche markets. And
some – hydrogen, for example – offer potential in the future.
Yet many challenges remain in providing clean, abundant, reliable, and affordable energy. The United States is still
dependent on traditional energy sources, including oil, gas,
and coal. Reserves are not unlimited, and the demand for
energy is growing steadily. New energy technologies will be
needed to stave off the mounting threat of climate change.
It is widely accepted that technological progress accounts
for up to one-half of the nation’s economic growth. Clean generation and efficiency technologies will yield benefits to our
quality of life, our national security, and our prosperity. Yet
with our current mature energy infrastructure, how can new
technologies be developed and mobilized? In order for new
energy products, processes, and services to take root and
flourish, a combination of visionary public policies, partnerships, and education will be needed.
Public policy
The speed at which energy efficiency and renewable
energy technologies will develop and make large contributions will depend on the kinds of policies that are used to
encourage their deployment. Policies can range from those
aimed at commercialization, subsidizing the production of
renewable energy through mechanisms like the production tax
credit for wind and biomass, to those targeting brand-new
ideas, helping to fund research and development for nascent
technologies.
Energy legislation has been enacted over the past decade
to increase the use of energy efficiency and renewable energy.

The Energy Policy Act of 2005 includes tax incentives and
loan guarantees for energy production of various types. A
major provision in the Act is a Renewable Fuel Standard to
increase the amount of biofuel (28.4 billion L/7.5 billion gal
by 2012). The Biomass Research and Development Act of
2000 focused research efforts on bioenergy. Agricultural legislation such as the Title IX of the 2002 Farm Bill (Farm
Security and Rural Investment Act of 2002) has also been
used to encourage the use of renewable energy systems on
farms and ranches. In addition, environmental legislation has
recognized that there is a significant opportunity to reduce
pollutants and greenhouse gas (GHG) emissions by reducing
and replacing fossil energy with energy efficiency and renewable energy. The Clean Air Act Amendments of 1990 encouraged the use of alternative fuels such as ethanol to help reduce
carbon monoxide and ozone problems.
The Advanced Energy Initiative (AEI) was announced by
the Bush Administration in early 2006. It increased funding
Total Section 9006 funding over the period FY 2003-2006 was approximately
$122 million (including $88 million on grants and $34 million in loans).

for clean-energy technology research at
the U.S. Department of Energy (DOE).
The AEI included a Biofuels Initiative
to foster breakthrough technologies
needed to make cellulosic ethanol costcompetitive with corn-based ethanol by
2012 and a Solar America Initiative to
reduce the cost of solar photovoltaic
technologies so that they become costcompetitive by 2015.
President Bush’s 2007 State of the
Union Address included a proposal for
the United States to use 132.5 billion
liters (35 billion gallons) of renewable
and alternative fuels by 2017. The
President called for greater use of wind
and solar energy, expanded use of clean
diesel vehicles, and accelerated
research on the batteries needed for
plug-in hybrid vehicles. He also issued
an Executive Order instituting new
guidance for energy efficiency, use of
renewable energy, and reduction of
environmental impact throughout the
federal government.
The federal government and a
number of state governments are developing and adopting government procurement preference requirements
which can help “pull” technologies and
products into the market. One example
is the Federal Biobased Products
Preferred Procurement Program, which
requires all federal agencies to preferentially purchase biobased products.
In addition to the federal government, many states have enacted policies
to reduce energy use and move towards
reliance on renewable energy and fuel
technologies. Some states have policies
to make it easier for renewable energy
providers to connect to the energy grid
by adopting far-reaching interconnection and net metering standards. Others
are increasing investment in the construction of “green buildings” and
energy efficient homes and offices
through innovative financing and
incentives, and passing appliance efficiency standards that go beyond federal
government requirements. Some states
have passed measures to improve transportation infrastructure by investing in
cleaner state government fleets, better
public transit systems, and innovative
new technologies like plug-in hybrids.
While past efforts have been
invaluable, more intensive policy
efforts could further accelerate the use
of efficiency and renewable energy. For
example, energy efficiency and renewable energy improvements are difficult
to monetize but some consumers are
willing to pay more for “green” energy
in recognition of its benefits. Green
pricing is currently an optional service
or tariff offered by utilities to customers
in regulated electricity markets.
Implementing programs such as these
more expansively across the country
could help to increase the use of these
technologies. Similarly, a number of
states have Renewable Portfolio
Standards (RPS) that ensure that a minimum amount of renewable energy is
included in electricity resources. Some
states have substantial percentage RPS
goals of 20 percent or more. Policies
like these enacted in more states and/or
nationwide could help to accelerate the
use of these technologies. On the horizon, policies to curb carbon emissions
promise to further accelerate the use of
cleaner technologies such as efficiency
and renewable energy.
Partnerships
Bringing a new technology to
fruition is enhanced through public-private partnerships. Government can
serve as a catalyst, facilitating cooperative work between the public and private sectors and among industry,
universities, and non-profit organizations. The public sector helps by reducing the risk involved in developing
high-risk, high pay-off technologies.
The private sector brings market perspective, and the resources and expertise needed to develop new products and
bring them to market. Partnerships create synergy by pulling together fragmented technical efforts. The
complexity and multidisciplinary
nature of renewable technologies often
exceed the capabilities of single firms.

A variety of partnerships, both among federal agencies
and in the private sector, are playing an important role in
helping to develop and disseminate new energy technologies.
Some examples of partnerships pursuing energy efficiency
and renewable energy technologies are provided.
A private sector partnership, British Petroleum/DuPont,
was recently formed to develop, produce, and market a next
generation of biofuels to help meet increasing global demand
for renewable transport fuels. ENERGY STAR, a public sector partnership, is a joint program of the U.S. Environmental
Protection Agency and the U.S. DOE to help save money and
protect the environment through energy efficient products and
practices. The program estimates that it saved about $10 billion in energy costs in 2004 alone.
Another federal partnership involves Section 9006 of the
2002 Farm bill which funds grants and loans for the use of
renewable energy and energy efficiency technologies on
farms. The National Energy Renewable Laboratory, on behalf
of DOE, has been collaborating with the USDA to bring technical expertise in reviewing the specific technologies proposed in the grant and loan applications.
These are only a few of many partnerships that include
the administration’s Building America, Hydrogen Fuel
Initiative, and FreedomCAR partnership (as discussed in previous energy-focused articles).
Education
Informing citizens about efficiency and renewable
energy technologies will enhance the demand for these technologies. For example, when buyers of homes, home builders,
and lenders are knowledgeable about new energy-saving and
renewable energy technologies, they are more likely to purchase these products.
Educational programs also build long-term capacity and
create demand. Education is the process which will create the
next generation of scientists, engineers, and technicians
trained in energy efficiency and renewable energy technology.
In addition, educating youth will assure the adoption of these
technologies for years to come.
The land-grant university system is a highly effective system to engage in providing energy education and outreach
services. While all universities engage in research and teaching, the nation’s more than 100 land-grant colleges and universities, have a third critical mission: extension. Land-grant
institutions “extend” their resources, solving public needs
with college or university resources through non-formal, noncredit programs. These programs are largely administered
through thousands of county and regional extension offices,
which bring land-grant expertise to the most local of levels.
An initial program has been developed by the Office of
Energy Efficiency and Renewable Energy at the U.S. DOE
with the National Association of State Universities and LandGrant Colleges in the Pacific Northwest to provide expertise

Birdseye View
An Early Food Engineering Pioneer
William M. Miller
T
he word Birds Eye is synonymous with the frozen
food industry, originating with the inventor of quick
freezing, Clarence Birdseye, an early biological
engineer. Born in Brooklyn, N. Y., in 1886,
Birdseye exhibited keen interest in outdoor activities. By the
age of 10, he was trapping and selling muskrats. He studied
and practiced taxidermy in addition to taking a cooking class
in high school. Off to college at Amherst, he studied biology
and earned money for school expenses by trapping and selling
black rats to Columbia University for a genetics program and
live frogs to the Bronx Zoo for reptile food.
Because of financial constraints, Birdseye left Amherst
after two years and was employed as a naturalist for a USDA
biological survey in New Mexico and Arizona. That assignment was followed by a Rocky Mountain fever study in
Montana through the collection of ticks and their hosts. He
supplemented his income with furrier activities, buying hides
and selling them on return trips to New York.
Learning to quick freeze in Labrador
In 1912, Birdseye participated in a medical expedition to
Labrador in northeast Canada where he noted the high profits
from the fox fur breeding and trapping business. Undertaking
his own fur-trading enterprise, he observed native Inuit tribes
freezing fish on ice slabs and enjoyed the highly palatable
result. He reasoned that the still-fresh taste resulted from only
small ice crystal formation, minimizing any cell wall disruption. He intuitively knew that the proper manufacturing
process mimicking these conditions could lead to frozen food
items of improved texture, flavor, and color. While in
Labrador, he quick-froze vegetables for his family, to test the
concept beyond meat and fish.
Returning home in 1917, Birdseye was employed in both
private and public sectors culminating with an administrative
position with the U.S. Fishing Association through 1922. He
then undertook development of his quick-freeze concept with
a $7 investment in a fan, some brine, and ice.
Packaging innovation
Birdseye’s major advancement was packaging food products before freezing and holding the packages under pressure
exerted from either double-belt or flat-plat heat exchangers.
With ammonia refrigeration, freezing times to -18°C (0°F) were
reduced from 18 hours to 30 minutes for vegetable packages.
Birdseye’s principal “quickfreeze” patent was granted in
1930. His first company failed,
but new financial partners came
forward forming the General
Seafood Company in 1924. That
company was sold to Postum in
1929, and the General Foods
Corporation was established. At
that time, the now common
trade-name Birds Eye® was
introduced. Birdseye remained

declined. With development of
non-toxic Freon refrigerants, home refrigerators had been popularized in the 1930s. Birdseye helped grocery stores introduce frozen food display cabinets, which he developed, and
offered a leasing arrangement for them. He also designed display lighting for retail stores and heat lamps for food preparation. In total, he obtained over 300 U.S. and foreign patents.
His diverse patent portfolio includes a recoilless harpoon gun
and an electric fishing reel. Continuing his keen interest as a
naturalist, he authored with his wife, Eleanor, Growing
Woodland Plants in 1951.
Birdseye on Birdseye
“I do not consider myself a remarkable person. I did not
make exceptionally high grades in school. I never finished
college. I am not the world’s best salesman, but I am intensely
curious about things which I see around me, and this curiosity, combined with a willingness to assume risks, has been
responsible for such success and satisfaction that I have
achieved in life.” Such was Clarence Birdseye’s humble personal insight. Birdseye’s insightful view of nature coupled
with his technical skills makes him exemplary of early food
and biological engineering endeavors.

Rural Electrification
Bringing Light to Country Living
Gerald W. Isaacs
hen natural disasters like hurricanes and ice
storms interrupt electric service to homes and
farms, we find it difficult to live without electric power. Today, we even find it hard to
imagine what farm life was like in the “good old days” before
rural electrification. Kerosene lamps lighted homes. Early
morning or late night farm chores were done with kerosene
lanterns. Food was cooked with a coal or wood-fired range
(kindled each morning) and refrigerated with an ice box when
ice was available. Canning preserved most fruits, vegetables,
and meats. Water was hand pumped from a well and carried in
a bucket. Baths were in a wash tub; the toilet was “out back.”
Before the 1930’s, only a few farms lucky to be near
towns had electric service provided by municipal or investorowned companies. Still fewer had power for a few electric
lights and a radio from electric wind generators like the
Wincharger that maintained storage batteries. A few farms
had motor-driven Delco plants that also charged batteries.
A few farms located near large towns were fortunate to
receive “high line” electric power in the late 1920s. Our farm
first had electricity in 1935, and I recall the thrills of bright
lights at the flip of a switch, full time refrigeration, radio,
water under pressure, and indoor plumbing.
At first, farm applications of the new electric service
were mostly lighting for the barn and water pumped for the
livestock. I no longer had to pump water by hand on hot days
for those twenty thirsty steers in the feedlot. Watching the
marvelous transformation of electric power brought to our
farm caused me to make rural electrification my life’s work.
The tremendous economic and social potential of providing electric power to U.S. farms was first recognized by many
of the investor-owned electric companies. They were understandably reluctant to extend power lines to many rural areas
where farms were too far apart to make providing service
profitable. Thus, most would remain without service.
The U.S. Congress recognized this dilemma and passed
the Rural Electrification Act of 1935 and legislation authorizing projects like the Tennessee Valley Authority. These actions
provided federal assistance to extend power lines to most rural
areas. State universities and the USDA initiated extensive
research and education programs to develop and apply electrical technology to remove drudgery from farm work,
improve product quality, and increase worker productivity.
Electric power companies, electric cooperatives, and
equipment manufacturers early on recognized the need to pro-

vide technical assistance to farmers. Rural service advisers
and equipment manufacturers’ technical sales people played
an important role in helping farmers make profitable use of
the new technology. Many agricultural engineering graduates
were employed for this work by electric power suppliers,
equipment manufacturers, and public service organizations.
Rural Electrification became a major technical division
of ASAE serving those professionals who were developing
and applying new electrical technology for agriculture. The
technology reported through this division related to new uses
for electric power and electronics in agriculture, which frequently impacted the new technology developed by other
divisions. Drying and handling of shelled corn made feasible
the transition of corn harvest from ear corn picking to field
shelling, greatly increasing the efficiency of the entire harvesting operation. Electric-powered irrigation pumps and
irrigation controllers improved the efficacy of many forms of
irrigation. Electric-powered ventilation and feed handling
made it possible to raise animals in buildings.
Applications of electric energy to agriculture were always
carried out with due consideration of the effect on the profitability of the enterprise. Increased energy costs beginning in
the 1970’s brought greater attention to conservation, use of
alternative fuels and solar energy, which continues to this day.
The activities of ASAE’s Rural Electrification Division
eventually became so heavily involved in crop processing and
other post-harvest technologies that the division was renamed the Electric Power and Processing Division. In turn,
when food processing activity grew, the Food Process
Engineering Division was formed. The Rural Electrification
Division had historically been involved in electronic applications, such as automatic control, sensors, and information processing, thus the division was renamed the Information and
Electronic Technologies Division.
Much of the technology originally developed by former
members of the Rural Electrification Division is still in use
today and contributes greatly to the production of our abundant supply of quality food. Expansion of electric power service to almost all rural areas of the country has had
far-reaching social benefits, making it possible for non-farming homeowners to enjoy the benefits of rural living without
the hardships their farmer ancestors endured, at least until the
next hurricane or ice storm.

PE Licensure Celebrates 100 Years
A
SABE isn’t the only entity celebrating its centennial. This
year also marks the 100th anniversary of engineering
licensure in the United States. These two inceptions led to
the administration of the first state professional engineering (PE)
exam for agricultural engineering in the early 1950s.
A century ago, anyone could work as an engineer without
proof of competency. In order to protect the public health, safety,
and welfare, the first engineering licensure law was enacted in
1907 in Wyoming. In 1922, the American Association of
Engineers put forth a platform for engineering that included the
“passage of an engineers registration law in every state and the
enforcement of existing registration laws.”
By 1934 only 28 states had engineering registration laws
enacted. Montana became the last state to enact the laws in 1947.
Each state was responsible for administrating their own exams
and establishing the criteria for licensure.
The desire to create consistency from state to state led to
the establishment of one exam for all states by the engineering
discipline. The National Council of State Boards of Engineering
Examiners administered the first unified PE examination under
this new structure
1966. It would

Licensure demonstrates professional identity; increases credibility; demonstrates commitment to
the profession; provides a level of
expertise that can not be promoted
by
non-licensed
individuals;
enhances the potential for promotions,
job offers, and salary increases; and establishes a professional code of ethics for professional engineers.
According to the latest results from The Engineering Income
& Salary Survey, PEs earn an average of 20 percent more in
salary than engineers with no professional license. The median
income for an engineer with no professional license is $69,000
while a licensed PE earns a median salary of $86,000. Similarly,
PEs with a bachelor’s degree earn an average of 17 percent more
in salary than engineers with no professional license and a master’s degree. Certifications and advance degrees push PEs median
salary even higher.
ASABE provides a forum for members who have become
PEs through its Professional Engineering Institute (PEI). The
Institute supports and promotes those members who are licensed
engineering professionals and provides information on the
process needed to obtain a license. PEI also offers educational
opportunities to members by preparing individuals to take the PE
exam and providing continuing education courses and educational materials. To learn how to obtain a license or more information on PEI, visit www.asabe.org/pei/index.html.

Brooks Awarded the Merriam Scholarship
Elizabeth A. Brooks, a sophomore in the Agricultural and
Biological Engineering Department, University of Illinois at
Urbana-Champaign, was selected to received the 2007 John L.
and Sarah G. Merriam Scholarship.
“Before I began college, I was unsure
about my future goals, but as valedictorian
of my high school class, I wanted to be in a
curriculum where I was challenged, so I
chose general engineering,” says Brooks.
Shortly before graduating from high
school, Brooks was diagnosed with a
relapse of cancer. Her college years have
included several relapses and remissions
which have created delays in her studies while undergoing
treatment.
“Even though cancer has had a huge impact on my life, growing up on a family farm has taught me the value of hard work and
has deeply instilled in me the importance of our natural resources,”
Brooks says. “For that reason, I have chosen to major in agricultural engineering with a specialization in soil and water resources
engineering. I want to work in this field because I believe that
today’s agricultural practices will have an effect on the future, and
I want to ensure that we can preserve the land and environment as
much as possible in order to sustain future generations.”
Brooks has been a member of ASABE for one year.
Klein Receives Foundation Scholarship
Matthew P. Klein, a junior in the Biosystems and
Agricultural Engineering Department at Michigan State

YOUNG PROFESSIONAL COMMUNITY
Are You Engineering a Secure Financial Future?
So, now that you are out of school or have been out for a while,
what do you do with the money you are making? Spend it? Save it?
Enjoy it? Donate a large portion to the ASABE Foundation? Maybe
the best choice is a combination of all the options. There is nothing
wrong with enjoying some of the money you are now making and
even buying yourself something you have wanted for the past few
years. However, several steps should be taken to secure a successful
financial future. Sit down and assess your financial situation, make
a budget, outline your financial goals, and implement your plan.
A good way to assess your financial situation is to develop a
net worth statement. It is an easy process and simply consists of
summing your assets and liabilities to calculate your net worth. If
you are fresh out of school and the number is negative, don’t
panic! This is normal at this stage of life and will soon change.
A good practice would be to use a software package such as
Microsoft Excel™ and save your net worth statements, which should
be done on an annual basis. You will be surprised how fast your net
worth can grow! Now that you have a better feel of where you stand
financially, it is time to get your spending in check with a budget.
It is a good possibility that you either have a budget now or
at least have experimented with a budget in the past. Whether you
do a simple budget with a piece of paper and pen or use a more
elaborate financial software package, the most important aspect
is that you create a budget. This helps to cast light on just how
much money you have been spending on your love for gourmet
coffee, eating out for lunch, or weekend activities. Cutting back
on some of these could save you a lot of money over the next
year. After developing your net worth statement and creating a
budget, you should have a pretty good hold on your financial situation and be ready to set some all-important goals.
What are your financial goals? Buy a home? Save 10 percent
of your income? Become a multi-millionaire at the age of 40 and
live out your days sipping margaritas on some remote Mexican
beach? (Sorry, got a little carried away with that last one.) You
should create both short-term and long-term goals. Write your
goals down and save them as a reminder of where you want to be
and what you are working toward. Time is one of the most important factors when investing. That is why you need to set your
goals today and make time start working for you and your investments. Now that you have all of the tools in place, your question
might be, “What next?” That question is answered by looking at
the information you have derived from your financial assessment,
budget planning, and your goals.
You are now ready to implement your financial plan. A good
way to get specific advice customized to your situation is to get
a financial planner from a company such as A.G. Edwards,
Northwestern Mutual, or ING. They can present you with your
options and should provide this service at no direct cost to you.
If your company has a 401k matching plan, you should be contributing the maximum amount your company will match before
doing anything else with your options. Other options to gain
interest on your money are a money market, Roth IRA, whole life
insurance plan, as well as others. Your specific choice will most
likely depend on how much liquid capital you need, the level of
risk you are comfortable with, and the amount of time you are
planning on investing.
Finally, what about a home? With the housing market where
it stands, there is a strong possibility some good deals exist in
your area. A house can be an excellent investment. There also are
numerous tax advantages to owning a home. The more you educate yourself and get acquainted with the areas you are interested
in, the better the chance you will find a good deal and make a
solid investment in real estate. Hopefully you are now ready to hit
the ground running towards your bright financial future!

Inaugural Article Published in New Invited Review Series
Soil and Water Division Editor Wes Wallender announced
the first article in the newly established Invited Review Series.
The division asked associate editors to suggest leading
ASABE researchers who might contribute. The associate editors
selected Philip W. Gassman from a list of nominees to prepare a
review paper on a subject of his choosing.
Gassman, along with his colleagues Manuel R. Reyes,
Colleen H. Green, and Jeffrey G. Arnold, prepared “The Soil
and Water Assessment Tool: Historical Development,
Applications, and Future Research Directions.” This extensive
effort will impact the use of the Soil and Water Assessment
Tool (SWAT) worldwide. The 40-page review article with 286
references was published in this year’s Transactions of the
ASABE, Vol. 50, No. 4.
Associate Editor Jane Frankenberger, in charge of guiding the
manuscript through the review process, lauded the contribution.
“It was a pleasure to oversee the review of such a thorough, complete, and useful review of SWAT and its applications.
I believe this will make a very substantial contribution to the
literature and especially to the wide variety of researchers and agency
personnel that are using SWAT. Your considerable attention to the
details of how it has been used around the world will be appreciated.”
The Soil and Water Division’s next effort will be a
Centennial Collection appearing in Transactions of the ASABE
this fall. Contributing authors include former recipients of
ASABE’s Hancor Soil and Water Engineering Award as well as
other leading scientists. The authors will be chosen by the associate editors and division editor.

STANDARDS
Spotlight on Insurance and Ag
Driveline Industry Standards
Supporters
Continuing our highlights of various Standards Program
supporters, ASABE would like to thank supporters from the
insurance and agricultural driveline industries.
The agricultural driveline industry is served by a small group
of companies that manufacture a large percentage of the drivelines
in use. Two long-time supporters of the ASABE Standards
Program are GKN Walterscheid and Weasler Engineering. They
have provided financial assistance and subject matter experts for
standards work. Engineers from the two companies have led standards projects and technical committees and contributed a great
deal of knowledge and expertise in design and safety for the
Society. GKN Walterscheid, with offices and facilities worldwide,
manufactures drivelines, clutches, and gearboxes for agricultural
and off-road equipment. Founded in 1951, Weasler Engineering,
Inc. manufactures and distributes mechanical power transmission
products used in agricultural, lawn and turf, construction, industrial, and marine equipment. Weasler is headquartered in West
Bend, Wis., with other facilities worldwide.
One of the issues with drivelines, and many other parts of
agricultural equipment, is the safety of the operator. One industry that is key in helping with research, standards, and other
safety items for the agricultural, food, and biological industries,
is insurance. Insurance companies such as Grinnell Mutual
Reinsurance Co., based in Grinnell, Iowa, and Sentry Insurance,
headquartered in Stevens Point, Wis., have aided and promoted
the ASABE Standards Program for years. A few Farm Bureau
agencies and Sentry have contributed financially to the program.
Two employees of Grinnell, Larry Wyatt and Gary Downey, have
provided a great deal of input on how ASABE Standards benefit
the insurance industry. This expertise has led to several outreach
visits to other insurance companies as well as continuing the relationship the Society has with the National Association of Mutual
Insurance Companies (NAMIC). ASABE Director of Standards
and Technical Activities Scott Cedarquist recently attended and
presented at the NAMIC Loss Control Committee meeting in
Springfield, Ill., at their request.
ASABE Standards have a large amount of safety content,
which directly affects many sectors of the agricultural industry.
Companies such as GKN Walterscheid, Weasler, Grinnell, and
Sentry understand the impact these standards have on their businesses. They realize that supporting the ASABE Standards
Program is a vital part of promoting safety for their companies
and their customers.
ASABE takes this opportunity to thank all companies that
support the program through financial contributions, member
support, and encouraging their employees to work on standards
development. If it were not for these dedicated companies and
individuals, the ASABE Standards Program would not be
successful.

The Vision that Cut Drudgery
from Farming Forever
This is the intriguing story of Dr. J.
Brownlee Davidson who, at a very
young age, is credited with
launching the agricultural engineering profession. At the age of
25 he was assistant professor in
charge of the Department of Farm
Mechanics at Iowa State College
(later University) which, with his
guidance, soon evolved into the
first four-year agricultural engineering curriculum. He went on, with like-minded others, to
form the American Society of Agricultural Engineers in 1907.
Author ASABE Past President Sherwood S. DeForest, a former
student of Davidson, describes him as an “extraordinary man
with a vision.” Must reading for anyone involved in the profession and sure to be of interest to the general public who have

The soy-based flexible foam, which uses a five percent soy-based polyol, will be incorporated into seat
backs and seat cushions in the 2008 Mustang. This is
done without compromising the durability, stiffness, or
performance of the foam.
Ford researchers are working to replace 40 percent
of the standard petroleum-based polyol with soyderived material. At this level, using this soy poly-urethane is estimated to result in as much as $26 million in
annual cost savings for Ford. According to the National
Institute of Standards and Technology soy polyols have
only one-quarter the level of total environmental impact
of petroleum-based ingredients.
The idea of using soy in Ford’s manufacturing
process is nothing new to the American car company.
The Ford Model T contained car body parts made from
soy fiber. The soybean’s oil was used in automobile paint.
Through years of work with the United Soybean Board
and industry partners, Ford developed the Model U concept car in 2003, which featured soy-based seat cushions as well as a soy-based resin composite tailgate.
“As we move forward to develop a portfolio of sustainable materials that will go into future Ford vehicles,

Enormous public sports spectacles present a host of logistical engineering challenges. From facility
design to equipment development,
traffic needs, security, and communications and information technology,
engineering is critical to ensure that an
event runs smoothly and efficiently.
To add a creative aspect to the

all participating students to create a
t-shirt design that incorporates the
TEAMS “behind-the scenes” theme.
Students at every competition will
receive a free t-shirt, ensuring that one
student’s design will be worn by thousands of fellow students across the
United States. In addition, the design
will also appear on the front cover of
the TEAMS competition set. A panel
of judges from Shell will choose the
final winner.
To dispel the notion that engineering is bound by the limits of math and
science, the t-shirt design contest
underscores the importance of creativity in the engineering process and the
career possibilities in engineering for
those with an artistic bent.
“Encouraging a broad range of
students in high school to study math

“Developing these skills early will help
prepare students for a future career in a
technology-driven field. For Shell, the

Visible Food
Packaging Can
Reduce Shelf Life
Packaging that lets consumers see a
food product may not be good for the
food. New ideas for plastics may help
remedy that problem. Research by
Virginia Tech food scientists has provided significant evidence that visible
wavelengths of light cause taste and
odor changes in food.
Materials research for protecting
food from light damage focuses on
UV light in the range of 200 to 400
nanometers, the range that can damage
human skin.
“These are the same wave lengths
that cause nutritional and sensory
damage in food,” says Susan Duncan,
professor of food science and technology. “For example, visible light
degrades riboflavin in milk, interacts
with flavor and odor molecules, and
causes pigment damage in food.”
Ultraviolet wavelengths are not
the only ones that cause damage, but
they are important from the perspective of food processors, who want beverages, such as milk, to look
appealing. Packaging has moved away
from paper board to polymers such as
polyethylene, so the consumer can see
the product. “Then they started to have
color and flavor problems,” says
Duncan.
Adding UV absorbers to the packaging helped and still allowed the consumer to see the product, but it didn’t
totally resolve the problem.
“The only way to completely protect the product is to use a totally
opaque container. But generally, consumers like to see a product, particularly milk – to make sure it isn’t
curdled – or juice, to make sure there is
no sedimentation, explains Duncan.
But we also want a product to have a
long shelf life.
The Virginia Tech researchers
have tested a number of new materials
that are not currently being used
for food packaging. One material, a
translucent sleeve over wrap with
an iridescent shimmer, reflects wavelengths. “We found evidence of
improvement, but it is still not as good
as opaque,” Duncan says.
She believes that material scientists
can develop better materials, once they
become attuned to the challenges of
food packaging. “We want to find manufacturers to work with us to develop
packaging products that will work with
milk and the visible wavelengths. Food
scientists and material scientists working together is what is on the horizon.”

Duncan, [email protected].
Charcoal Technology Holds Promise for Developing Countries
Massachusetts Institute of Technology
student Jules Walter has seen firsthand the impact of deforestation in his
native Haiti. Nearly 98 percent of the
island’s forests are gone, and more
trees are being cut down every year.
Deforestation is not only an environmental problem in that country, but it
also makes life difficult for Haitians
who rely on wood to cook their food.
Walter and a team of students are
working to bring affordable, environmentally friendly cooking fuel to developing countries like Haiti. Their
technique offers a simple way to produce charcoal briquettes from organic
material such as sugarcane waste.
The energy source for the charcoal
comes from bagasse, or sugarcane
waste. Sugarcane is widely available in
Haiti, and corncobs and other plant
wastes, including banana leaves, can
also be used to make the charcoal.
Several families in Haiti have
tested the briquettes and liked them
better than wood charcoal, Walter
says. The briquettes are good for
cooking because they burn longer
than wood and are easier to light. They
also create less smoke than wood and
dung fires.
The production process has three
steps. First, organic waste is carbonized in a drum in a low-oxygen
environment, which prevents it from
turning to ash. Second, the resulting
powder is mixed with a binder to help
hold it together. Then, the powder is
pressed it into briquettes with a simple
machine press and allowed to
dry. The entire process takes
two and a half to three hours.

LAST WORD
Who me? A PEV?
Yes! ASABE wants YOU as an ABET program evaluator!
Beginning this fall, ASABE is the sponsoring society for two ABET program criteria, agricultural engineering and biological engineering. ABET, Inc. is the
accrediting agency for all engineering educational programs in the United States (and many around the globe).
Volunteers are needed to serve as educational program
evaluators (PEVs) in both agricultural and biological
engineering. Graduation from an ABET-accredited program is usually a necessary criteria to become licensed
to practice engineering anywhere in the United States.
Thus, agricultural and biological engineering academic
programs relies on an ABET accreditation for survival as
viable programs.
chair and faculty. Activities may include interviewing
students and faculty, observing classes, surveying lab facilities, and reviewing course materials and student work.
Step 3. Based on a review of the self-study report
and observations made on campus, the PEV formulates
a draft statement on the adherence of the program to the
evaluation criteria. This statement is submitted to the
team chair and incorporated in an exit statement to the
program(s) and institution at the end of the visit.
Step 4. The PEV travels home and completes
expense reports and performance evaluations of his
visit-team members. The PEV may also need to respond
to questions during the statement-editing period.
What do PEVs do?
PEVs volunteer through ASABE (an ABET member
society) to evaluate postsecondary degree-granting programs in either agricultural or biological engineering.
PEVs are dedicated technical professionals with interests in contributing to the profession and improving
higher education. Evaluators are team players, respected
in their fields and among their peers, and are often active
in ASABE. Good communication as well as interpersonal
and organizational skills are musts for successful PEVs.
Engineering educational programs (not departments) are evaluated against a set of general and program specific criteria developed, in the case of
agricultural and biological engineering, by ASABE
through ABET. The criteria outline the requirements for
faculty, facilities, curriculum, and other key areas. PEVs
determine if the criteria are met.
What are the required qualifications?
The criteria is straightforward. One must have:
1. A demonstrated interest in improving education.
2. Membership in ASABE or another ABET society
sponsoring biological engineering criteria or a willingness to become a member prior to applying to serve.
3. Formal education and recognized distinction in
his or her field. Program evaluators with an industry
background must possess a degree appropriate to the
field; experience in the employment of graduates from
accredited programs is desirable. Program evaluators
with an academic background must possess a degree
appropriate to the field; accreditation process experience is desirable.
4. Internet and e-mail access and proficiency in
word processing programs (compatible with Microsoft
Word and Word Perfect), spreadsheets, and PDF files.
5. Other minimum qualifications as required by
ABET’s member societies (i.e., a PE license).
A PEV’s work takes a four-step process
Step 1. Work begins with the receipt of a self-study
report, submitted to ABET by an accreditation-seeking
program. The report contains general information about
the program and institution and specific details on how
the program meets evaluation criteria. The PEV thoroughly reviews the information and, if needed, communicates with the program/institution directly to resolve
any ambiguities or to answer any questions.
Step 2. The PEV travels to campus with one or more
other PEVs and an evaluation team leader (called a team
chair). On campus, a PEV spends about two days investigating his or her assigned program with the help of the
