Pepaid™ amino acid fertilizers are grouped into three current ingredient series: animal-derived enzymatic peptides, animal-derived free amino acids, and plant-origin protein hydrolysates with a corn-fermentation grade. Source and grade selection guide their use in crop-nutrition formulations.
EA series: animal-derived enzymatic peptides
EA80, EA80-LMW and EA80-uLMW use animal protein sources. Their molecular-weight ranges distinguish base-fertilizer and root-zone programs from lower-molecular-weight options for transplanting and abiotic-stress programs.
HA series: animal-derived free amino acids
HA80 uses meat proteins. HA40, HA20L and HA20-LLC use hair and feather protein sources. The range includes powder and liquid formats with different amino acid, nitrogen and chloride limits.
HA20-LLC is the low-chloride liquid name used on our website. Select a liquid or powder according to dosing equipment, dilution and crop chloride tolerance.
Plant-based series: EP60, EP60P and FP90
EP60 is a corn-protein enzymatic hydrolysate. EP60P is a soybean-protein enzymatic hydrolysate. FP90 is corn-derived and fermentation-based. These sources and processes should be identified explicitly in a plant-origin formulation.
Application planning
Match the grade to the crop, soil or foliar program, nitrogen target, chloride tolerance and water system. Amino acid inputs complement a balanced nutrient program; they do not establish disease-control performance.
Run dilution, tank-mix and crop trials before assigning a dose. Record crop stage, water quality and application conditions so results remain tied to the actual program.
