Why Amino Acid Nitrogen
Immediate Plant Uptake
Amino acids are the end-product of nitrogen metabolism. EcoGro WSP delivers N in the form the plant actually uses — bypassing the 5-step nitrate reduction pathway and saving up to 22 ATP per amino acid.
Zero Clay Fixation Loss
Unlike NH₄⁺, amino acids are zwitterionic and do not bind to negatively charged clay particles. In heavy clay soils (CEC 35+), this means 88% of EcoGro N reaches the plant vs. as low as 28% for liquid ammonium.
100% Water Soluble Powder
Fully dissolves in irrigation water — compatible with drip systems, fertigation lines, and foliar spray equipment. No residue, no clogging. High N analysis (16%) means lower shipping weight per unit N applied.
Disease Suppression via ISR
Soy protein hydrolysate triggers Induced Systemic Resistance through jasmonic acid and salicylic acid pathways, reducing disease severity by up to 62% in field trials on strawberry and vegetable crops.
Nutrient Chelation
Amino acids naturally chelate micronutrients (Fe, Zn, Mn), forming stable complexes that remain plant-available across a wider pH range than synthetic chelates.
Builds Soil Biology
Feeds beneficial PGPR, N-fixing bacteria, and mycorrhizal fungi. Long-term use increases microbial diversity and soil organic matter — the opposite of what liquid ammonium products do.
