Agricultural polyglutamic acid is a green environmentally-friendly fertilizer synergist that can increase fertilizer utilization from 30-35% to 40-50%, with an average utilization increase of 7-12% in nitrogen fertilizer, an average increase of 10-25% in crop yield and even 60% in some crops.

Product Feature

1, Moisture absorption and retention

γ-polyglutamic acid is highly soluble in water and contains over 1000 super hydrophilic groups (-COOH) in the molecules. The maximum water absorption ratio can reach 1108.4 times, which can fully retain moisture in soil and have ideal release effect.

2, Have the effect of slow and controlled release, and improve the utilization rate of fertilizer

There is a large number of free negative carboxyl groups in the long chain of γ-polyglutamic acid.Nutrients, stored temporarily unused by plants, inhibit the rapid decomposition and loss of fertilizer components and directly reduce fertilizer use amount above 20%, and make fertilizer in the soil release time four times.

3, Improve soil physical and chemical properties

It can improve the water retention, water permeability and air permeability of soil. Balance soil PH to avoid long -lasting use acid soil caused by fertilizer and soil consolidation.

4, Green biodegradable

It is a polymer of d-glutamate and l-glutamate that forms the peptide bond through the glycosyl-amino group and 10-carboxyl group. It can be decomposed into glutamate monomers in the natural environment. Glutamic acid is the amino acid required by the human body. Environmental protection is harmless.
