What Is Soy Amino Acid Liquid Fertilizer?

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.

Key Benefits of Soy Amino Acid Liquid Fertilizer

Enhances Nutrient Uptake Efficiency

Free amino acids act as natural chelating agents, improving the absorption and transport of nutrients such as calcium, magnesium, iron, and zinc inside plants.

Promotes Root Development & Vegetative Growth

Soy amino acid liquid fertilizer stimulates root elongation, enzyme activity, and chlorophyll synthesis, resulting in stronger plants and faster growth.

Improves Stress Resistance

Regular application helps crops tolerate:

  • Drought stress

  • Heat and cold stress

  • Salinity

  • Transplant shock

Increases Yield & Crop Quality

  • Improved fruit size and firmness

  • Better color and uniformity

  • Higher sugar accumulation

  • Longer shelf life
