TAMARACK® Plant Nutrient
Introduction
TAMARACK is a specialty plant nutrient based on amino acids and peptide chains
from hydrolyzed proteins. TAMARACK may be applied as a foliar spray or soil
applied via fertigation, drip, or drench. TAMARACK was commercialized in the
1970s and is sold in various countries around the world.

Benefits of TAMARACK
•Enhances yield (quantity and quality) under normal and stressed growing
conditions by increasing development and retention of fruit and flower set via
enhancement of pollen germination.
•Mitigates yield losses under stress conditions (salinity, extreme temperatures,
drought, etc.) especially in conjunction with critical plant developmental stages
(i.e. during rapid growth, flowering and/or fruit set).
Mechanisms of Action
•Gene activation - stimulates plant gene response to stress conditions is boosted
by Tamarack for quicker recovery from stress.
•Improves nitrogen use efficiency – activates key plant enzymes involved in nitrogen
metabolism for improved growth and yield.
Use Recommendations
TAMARACK applications may begin as early as the vegetative growth stages
but most importantly should occur during the critical reproductive phases from
flowering to fruit set and during fruit sizing periods.
Rate: 1 to 8 pts/acre*
Application Number: 2 to 3*
Application Timing:
•Permanent Crops: flower formation, flowering, early fruit set and sizing
Compatibility: Tamarack is compatible with most commonly used fertilizers and
pesticides. A jar test may be used to quickly confirm compatibility with specific tank
mixtures.
*Always read and follow the Precautions and Direction for Use as listed on the label.

Alternate rows were sprayed on 2/10/12
(prebloom) and 2/16/12 (postbloom). Using
$1.75/lb almond meat, the ROI at this location
was $41/acre for every dollar spent.

KEY
Tamarack and potassium acetate application improved leaf blade potassium
and brix levels during the period of warm, sunny weather typical of fall. When
cooler, wetter weather began, the combination still provided higher brix levels
and juice pH versus the untreated control.
