Polyglutamic acid is another polyamino acid obtained through biosynthesis independently researched in my country. It was included in the national "863" project "Research on the Preparation of Biodegradable Polyglutamic Acid Functional Materials" (2002AA327030) With funding, this research group completed research on the synthesis of polyglutamic acid, and the production technology has independent intellectual property rights (patent number: ZL021517460). Explored the development of γ-polyglutamic acid plant nutrition promoter products, determined the processing technology and formula of γ-polyglutamic acid liquid and dry powder dosage forms, and committed to cooperate with fertilizer companies to develop γ-polyglutamic acid additives Development and application of fertilizer products.

It has a wide range of applications and can be blended with fertilizers to produce various long-acting compound fertilizers and special fertilizers, and mixed with pesticides and herbicides.
