Abstract:
There is disclosed a fertilizer composition comprising a water-insoluble slow-release reacted nitrogen fertilizer and an effective amount of a water-soluble, non-aromatic poly(amino acid) of the group poly(aspartic acid), poly(glutamic acid), poly(glycine), poly(lysine) a copolymer of cystein and glutamic acid and a terpolymer of cystein and glutamic acid and aspartic acid, wherein the poly(amino acid) has a molecular size larger than that which can be absorbed by a plant. A method of making and using the fertilizer composition is also disclosed.
