Max AminoAcid 50 is a highly efficient animal sourced amino acid derived from feathers, extracted through hydrolysis process by hydrochloric acid. Feather-derived amino acids are rich in cystine and serine, which can promote tissue differentiation of plant cells, accelerate the germination process, and enhance plant growth vitality. In addition, cystine helps plants resist oxidation and enhance stress resistance, while serine can improve plant metabolic activities, increase nutrient absorption capacity, and promote healthy and rapid growth of crops. This product has a significant effect in promoting plant growth, increasing yields, and improving crop stress resistance.
