The application of amino acid fertilizers in soybeans mainly reflects in promoting pod formation, enlarging seeds, enhancing resistance to adversity, and increasing yield and income.
Promoting Pod Formation and Improving Pod Quality
Amino 80 fertilizers can increase the number of root nodules in soybeans (from 20 to 28 nodules per plant), enhance nitrogen fixation efficiency (nitrogen fixed increases by 30%), and reduce the empty pod rate (from 25% to 5%). At the same time, they promote pollen tube elongation (length increases by 25%), raising the pod setting rate from 60% to 85%.
Enlarging Seeds and Enhancing Fullness.
Using amino acid 80% fertilizers during the grain filling period can increase seed volume by 20% (diameter increases from 0.8 cm to 1.0 cm), and reduce the rate of shriveled seeds from 20% to 5%. Throughout the entire growth period, the weight of 100 seeds increases by 33% (from 18g to 24g), and the marketable rate increases from 75% to 95%.
Enhancing Resistance and Reducing Premature Aging.
Amino 80 of amino acids 80% can regulate the osmotic pressure balance in soybeans, enhancing drought resistance (the closure of leaf stomata is delayed under drought conditions) and cold resistance (cell sap concentration increases, lowering the freezing point). They also promote root growth, increasing root depth and reducing early aging phenomena.
Yield Increase and Economic Benefits
With the comprehensive increase in the number of pods and seed fullness, the yield can reach 3300 kg per Ha (a 47% increase compared to untreated plots). In some areas places like South America, due to high protein content and good market performance, the purchase price per ton is USD50 higher than that of ordinary soybeans.
