                                          Application ofg-PGA in agriculture

Gamma-poly-glutamic acid (g-PGA), is a polymer of the amino acid glutamic acid (GA). It is a major constituent of the Japanese food natto, and can be produced by bacterial fermentation.

       PGA is a water-soluble, water binding, and biodegradable, natural bio-macromolecular material which is non-toxic towards humans and the environment.            

PGA can be used as a fertilizer by dilution of its microbial fermentation solutions, which contain free PGA, amino acids, sugars as well as minerals, and can be safely applied directly to crops.

     The basic principles for improving soil quality, increasing crop yields and quality are as follows.

Firstly, improvement of the chemical composition of the soil:

Secondly, long-lasting releasing effect.

Thirdly, enrichment of nutrients, and improving the effectiveness of fertilizers.

It can enrich nitrogen, phosphorous, and potassium as well as calcium, magnesium, manganese and zinc in soil, thereby satisfying the different requirements of individual crops.After application of PGA, the effectiveness of nitrogen fertilizer can be increased by 50-60%, phosphorous more than 5%, and potassium 15-20%. It saves about 20% in fertilizer requirement per acre and is able to provide sufficient nutrients for crops.

PGA compound fertilizer technology

It is simple to use PGA compound fertilizer, only necessitating the dilution of a stock solution that is applied it directly to root areas. Spraying with a1000-fold dilution of PGA directly onto leaves enhances the effects. The working concentration for individual crops is different, usually 30-300 g/acre.

Research shows that PGA as a compound fertilizer is more profitable than other similar products and the market demand is also very large.
