AmiStar® 400 is obtained from soybean cake and is completely water soluble. Additionally, it provides organic nitrogen in free amino acid form which can be directly used in plant. Amino has the advantage that it adheres very well to leaves, because of its high viscosity, and it acts as an organic chelator of certain trace elements. Therefore it is widely used as a foliar fertilizer in combination with other water soluble fertilizers and in combination with almost all commercial plant protection agents to enhance their efficiency.
