Ideal Timing for Haylage Harvest
The Food and Agriculture Organization of the United Nations has declared 2014 the International Year of Family Farming. Main Office: 5242 Curtis Road, Warsaw NY 14569 Randolph Office: 91 Jamestown Street, Randolph NY 14772 May 21, 2014 Ideal Timing for Haylage Harvest What a difference a year makes! At the writing of this newsletter last year, we were warning that native orchard grass was heading and hay harvest wasn’t far behind. This year we have not had dry enough weather to get corn in the ground. But, there is a season for everything, and hay harvest will come in due time. Harvest timing is of the utmost importance for quality, and varies depending on the make-up of your stand. We use the physiological stage of grass to decide when to mow pure stands for dairy quality feed. The boot stage –just before the head emerges from the sheath - is considered the ideal time to mow for quantity and quality. Native orchardgrass usually matures 5-7 days before newer orchardgrass varieties that are bred for later maturity. Canarygrass generally matures 5-7 days after newer orchardgrasses. Mixed alfalfa/grass stands should be evaluated based upon the table below from Dr. Jerry Cherney of Cornell. Use this table by evaluating the height of the tallest alfalfa in different areas of the field and the percentage of grass in the stand. Table – Estimated NDF of a mixed alfalfagrass stand based on alfalfa height and the percent grass in the stand. Target NDF for each mixture is highlighted. Using the table to the right , a field with 40% grass and 60% alfalfa will be ready to mow when the tallest alfalfa stems in the field are 26” tall. Even though the weather has delayed entry into the fields this year, it is important that you keep track of hay development. A sudden break in the weather with warm temperatures could hasten crop development. If your hay reaches the defined stage for harvest and there is a window of good weather, plan on harvesting, even if it means putting the final corn planting on hold. You can’t afford to lose the quality of forage by waiting beyond ideal maturity. Page 2 WNYCMA SIGNS AVAILABLE THROUGH WNY CROP MANAGEMENT WNY Crop Management has an expanded inventory of available warning signs due to farm interest and demand. Many farms are reviewing areas on the farm requiring signs for periodic review of farm safety and in preparation for possible OSHA inspections scheduled for the summer of 2014. Now is a good time to inspect the farm to assess areas where signs were damaged or destroyed during the winter or to determine additional areas where signs are needed. Waste Storage Facilities should at a minimum, have warning signs posted at entrance / access points, agitation points and at least one per side, as close to eye level as possible. Large Waste Storage Facilities should consider additional signs along sides. Manuals, product literature and as-built construction drawings may also have Warning Sign recommendations. Confined Spaces also require Warning Signs and include waste hoppers and reception pits, storage tanks, & bins. Large signs: 10” x 14” Small signs: 7” x 10” All signs are hole punched in each corner for attachment. They are not adhesive, however you can likely purchase double-sided adhesive tape or magnetic strips. Signs come in Plastic or Aluminum For further information on sign requirements and additional OSHA regulations: Websites: OSHA standards and materials: https://www.osha.gov/dsg/hazcom/index.html NY Center for Agricultural Medicine and Health Key Focus: Enhancing agricultural and rural health by preventing and treating occupational injury and illness.

Time to Change Plans? Here we are again, well into May with a great deal of spring fieldwork yet to be done. With another wet spring reminiscent of 2011, we are wondering what really is an “average” year. Since things rarely seem to go as planned in farming, here are a few pointers to consider as you dodge raindrops to get the crops in. Dos and Don’ts to coping with this year’s weather: Don’t be inflexible. Your cropping plans for the year are just that: plans. Plans can always be changed based on new information. Here’s some new information: rain seems to keep coming and the date on the calendar keeps getting later and later. Do consider delaying seeding fields until the summer or next year. With an estimated 50% of the seedings planted, some of which have been washed away or are sitting under water, this is a very viable option to consider. If you have not already fall-killed or rutted up the hay fields you planned on putting to corn, you may want to leave them in hay and not seed any fields. The other option is to summer seed fields. Fall-killed wet, heavy ground is also a candidate for seeding instead of corn. The advantage to taking this strategy is that you just decreased your spring fieldwork by a significant amount of time and probably kept the same hay yield potential on your farm, for this year at least. The disadvantage? It sets your rotations back another year. Don’t put in your haylage too wet. Since this is not the first wet spring in the northeast, we can learn from the past. A similar year in the mid-90’s, the grass grew like you would expect in a wet year, but when it came time to harvest, it was still wet and overcast. Because of the soil moisture and overcast weather that year, the cut hay just didn’t dry. To feel it, it seemed dry, but the koster tester didn’t lie; it was still wet. Those who ignored the koster tester put up a lot of wet, butyric haylage that year. Coupled with the low sugars due to lack of sunshine, and the high lignin due to the cold, wet weather, not much milk was made on that haylage. You are better off having high NDF forage that cows will eat than a bunk of unpalatable slop. The recent return to wide swath practices will help enhance the dry down speed when your window for harvesting in limited. Also, being willing to ted the hay will further your potential for putting up haylage at the proper dry-matter. Don’t mud in your corn. The harm caused by plow layer and sidewall compaction is irreparable. You are better off putting in corn 10 days late, than mudding it in. Do try to trade in your long season corn for shorter season corn. Now is probably the time to consider switching to shorter season hybrids for grain; silage or high moisture corn can probably wait until the end of May. If the seed is not already in the ground when you receive this newsletter, grain growers should probably back off by 5 days in hybrid maturity, and another five if planting is delayed until early June, or consider switching corn acres to soybean acres. If your silage or high moisture corn planting is delayed until early June, consider reducing the maturity by five days. As last year’s data shows, there was really no yield hit to staying with long-season hybrids right up until June, but either harvest has to be delayed by 2-3 weeks, or grain moisture will be much higher. But again, anything can happen. In 2011, we had an exceedingly wet May allowing only for 24% of the corn to be planted in NY by 5/22 and 43% by 5/29. But then conditions turned exceedingly dry from mid-June through July before the drought was relieved in August. That year, the long-season corn planted in late May or early June yielded by far the best because it didn’t silk until the first week of August when the drought was relieved. As none of us will ever control the weather, we have to do the best with the hand we are dealt. Page 4 WNYCMA Corn Response to Sidedress vs. Y Drop Applications By Dennis Holland, CCA, Dupont Pioneer reprinted with permission from Crops & Soils magazine, March-April 2014 The growing season of 2013 was another interesting year for Midwestern producers—most notably record-breaking spring rainfall after the major drought of 2012. The excessively dry weather in 2012 reduced corn yields substantially, leading to more residual nitrogen left in the soil after harvest. While the heavy rains in the spring of 2013 were beneficial to replenish soil moisture, excess rainfall leached residual nitrogen out of the soil through tile outlets and into surface waters, which put nitrate pollution back in the news headlines. We are also entering a time when commodity prices are trending lower and producers are looking for ways to manage their inputs more precisely to increase profits. Improving nitrogen management is an excellent opportunity for producers to reduce nitrate pollution and increase profits. In the May–June 2013 issue of Crops & Soils magazine, I wrote an article summarizing a nitrogen study I conducted in the Treatment summary–2012 study • Untreated check—Base nitrogen program only: 2 reps/location • SuperU—50 units broadcast at V8 growth stage: 2 reps/location Sidedress UAN—50 units injected with a coulter at V4: 3 reps/location Y Drop UAN—50 units dribbled at the base of the plant at V12: 3 reps/location summer of 2012 where I compared different inseason nitrogen management strategies. Following are the treatment summary and yield results (Table 1) to review, and here’s the link where you can find the original article: www.agronomy.org/publications/cns/ articles/46/3/11. Y Drop attachments on a John Deere sprayer. Page 5 WNYCMA What struck me most after summarizing the results from this study was the difference between adjacent to the treatment split for the entire 2,200ft row length. the sidedress and the Y Drop treatments. These two treatments were both the same rate of UAN The results from 2013 (Table 2) indicate again that yields can be improved by managing the same solution but with different application timing and amount of nitrogen differently. These results show placement. So in 2013, I decided to set up a few more comparisons between sidedress application that options exist to increase production using the same amount of inputs. In this particular study, we and Y Drop application to see if I could find a similar response. see that applying the same amount of nitrogen at a different time and placing it closer to the base of Five fields were selected to compare sidedress the plant can result in increased yields. and Y Drop timing. Two fields were corn followed There are many ways Midwest corn growers by soybean, and three fields were continuous corn. can alter their nitrogen management plans to The continuous corn fields had a pre-plant nitrogen rate of 106 units applied in bands with a sidedress bar 4 inches deep. The corn followed by soybean reduce nitrates in the waterways and improve yields and profits. I encourage everyone to take a closer look at how making a small change to fields had a pre-plant nitrogen rate of 76 units, also applied in bands with a sidedress bar 4 inches deep. All fields had 30 units of UAN solution nitrogen management could help reach our goals. Have a safe and productive season, and see you in the fields! broadcast with herbicide, and then incorporated with one pass of vertical tillage before planting. Each of the five fields had treatment strips approximately 2,200 ft long. Twenty-four rows were treated with sidedress nitrogen beside 24 rows treated with the Y Drops. The sidedress nitrogen was applied in early June when corn growth stage was approximately V6. It was applied with a 60-ft sidedress bar with 30-inch coulter spacing set at four inches deep. The Y Drop nitrogen was applied in early July when corn growth stage was approximately V14. The Y Drop applicator is attached to a high-clearance sprayer boom and dribbles a stream of nitrogen at the base of the corn plants on both sides of the row. Both treatments were the same nitrogen rate of 70 units of UAN solution. The grain from each field was harvested with a John Deere S680 combine with a 12-row head, and data were collected with a calibrated John Deere GS3 yield monitor. The yield for each treatment at each field is reported for the 12 rows Page 6 WNYCMA By Nick Youngers Western New York Crop Management plans to utilize the Adapt-N program on several fields throughout our membership area. Adapt-N is a computer model that depicts rainfall events and plots data to determine what nitrogen losses have occurred. As we found out in 2013, these losses vary greatly based on soil types, rainfall amounts and frequency of rains. This will help us understand the trends of nitrogen losses due to rainfall events and refine our nitrogen sidedressing recommendations. In order to utilize the model, we will need to have complete, accurate records. Items needed for each field include variety day length; planting date; harvest population; nitrogen fertilizer date, depth, and type; previous crop; burndown date; percent legume; manure application dates and methods; tillage date and type; and, finally, percent residue. If we have incomplete or inaccurate information to enter into the program, we will get inaccurate information back. Although the Adapt-N system was developed, and continues to be fine-tuned, by Cornell University staff, it is no longer administered by Cornell. Now controlled by a private vendor, the use of the Adapt-N system is no longer free of charge. Western New York Crop Management Association has contracted a $1 per acre rate for the 2014 crop season. The board decided that the association will cover the cost of running 5% of the corn acres for any member enrolled in a crop program. If additional acres are desired, the farm will be charged $1/acre on the subsequent land. (One requirement of the vendor to note: the minimum field size for utilizing the program is 10 acres.) If you are interested in running specific fields, please contact your consultant.
