Soy Amino Acid Liquid Fertilizer is a plant-based biostimulant produced from soybean protein through enzymatic hydrolysis or fermentation. It provides crops with readily available free amino acids, peptides, and organic nitrogen that enhance plant metabolism and nutrient absorption.
Unlike animal-derived amino acid fertilizers, soy amino acid liquid fertilizer is odorless, stable, eco-friendly, and widely accepted in global agricultural markets. It is suitable for both conventional and sustainable farming systems.

Free amino acids act as natural chelating agents, improving the absorption and transport of nutrients such as calcium, magnesium, iron, and zinc inside plants.
Soy amino acid liquid fertilizer stimulates root elongation, enzyme activity, and chlorophyll synthesis, resulting in stronger plants and faster growth.
Regular application helps crops tolerate:
Drought stress
Heat and cold stress
Salinity
Transplant shock
Improved fruit size and firmness
Better color and uniformity
Higher sugar accumulation
Longer shelf life
