Get More With Less

Almond trial shows using less fertilizer compared to conventional treatments achieves equal to better results

Understanding Soil Quality

Almond acres have been steadily growing in California since the 1980s, and the crop is now California’s number one exported agricultural commodity. With over 2.4 million acres of trees planted, California grows over 85% of the world’s almonds. Virtually all commercially harvested almonds produced in the U.S. come from California. Most of that is due to the climate: warm, dry summers and cool, rainy winters are key to setting the tree up for success. But we know it takes more than a temperate climate to maximize a crop’s potential. AgroLiquid crop nutrition can be a
valuable tool in producing an abundant and quality almond crop. In an effort to determine the best sources, rates, timings and methods of application for this important crop, for the past two years, AgroLiquid has invested in
and run a full-scale research trial in almonds in California.

AgroLiquid has long believed in proving our technology through rigorous research and field testing. In western soils, we are looking at our technology performance compared to conventional fertilizer sources. Almonds are the perfect crop to test our Flavonol Polymer Technology, given how much potassium is needed to produce a crop. AgroLiquid’s
proprietary technology allows us to chelate/encapsulate nutrients within the sweet spot – not too loose, but not too tight. Our two year almond research trial has been conducted by Barat Basabri of Basabri Ag Research in
Newman, CA.

Trial details:
Each plot consists of five trees and was replicated six times across the orchard. Throughout the growing season, 50 gallons per acre (ga/A) of UAN-32 is applied as a constant in every plot.

Plot 1 (Conventional grower standard):
• 10-34-0 applied at 37.5 ga/A
• KTS applied at 40 ga/A
• EDTA Zinc (Zn) applied four times during the season for a total of 2 ga/A

Plot 2:
• Actagro’s Structure® applied at a rate of 25 ga/A
• KTS applied at 40 ga/A
• EDTA Zinc (Zn) applied four times during the season for a total of 2 ga/A

Plot 3:
• AgroLiquid’s PrG™ applied at 15 ga/A
• KTS applied at 40 ga/A
• EDTA Zinc (Zn) applied four times during the season for a total of 2 ga/A

Plot 4:
• AgroLiquid’s PrG applied at 15 ga/A
• AgroLiquid’s Kalibrate™ at a rate of 13.2 ga/A
• EDTA Zinc (Zn) applied four times during the season for a total of 2 ga/A

The results of the two-year averages are as follows. Plot 1: The “Grower Standard” of 10-34-0 + KTS yielded an average of 2,616 lbs. per acre. The second plot where Structure® was used in place of 10-34-0 + KTS, yielded a two-year average of 2,825 lbs./acre. The third plot was AgroLiquid’s PrG + KTS which yielded an average of 2,840 lbs./acre. The final plot was a full AgroLiquid program using both PrG + Kalibrate which yielded a two-year average of 2,829 lbs./acre. Yield results in the last three plots were comparable.
