Polyglutamic acid(γ-PGA) is a special anionic natural polymer, which is a homopolyamide formed by amide bonds between α-amine groups and γ-carboxyl groups. It contains tens of thousands of glutamic acid molecules. Molecular weights vary from 50,000 to 3 million Daltons. With excellent water solubility and strong adsorption, it can be used as water retaining agent, heavy metal ion deactivator, flocculant, sustained release agent and drug carrier, etc.Polyglutamic acid (γ-PGA) has the following properties:
1. Environmental friendliness
2. Excellent chelating adsorption capacity
3. Water absorption and moisturizing ability
4. Improves soil and good biodegradability.
As a fertilizer additive, polyglutamic acid has the advantages of less addition, low cost of use, and good growth promotion. The synergistic fertilizer with polyglutamic acid has significant effects of water retention, fertilizer retention, yield increase, stress resistance, and crop quality improvement. Polyglutamic acid (γ-PGA) is also an excellent biostimulant.
