PGA is a glutamic acid polymer produced by modern bio-fermentation technology. Its molecular weight can reach more than 3 million. Its large number of carboxyl groups in its side chain make it resemble a large comb, possessing chelating elements, absorbing water and moisturizing plants,regulating growth and other effects. PGA can increase fertilizer utilization by 30-50% from 30-35%, nitrogen fertilizer utilization rate by 7-12%, crop yield increase by 10-25%, and root crops(potato) increase by more than 60%. Now it become an very effective and ideal choice for fertilizer enhancer.

Specification:
Purity:≥4%

Function & Feature:
1)Super moisturizing ability.
The polyglutamic acid molecule contains more than 1,000 super-strong hydrophilic gene-carboxyl groups (-COOH), which can fully maintain the moisture in the soil.
2)Enrich nutrients and increase fertilizer absorption rate.
Carrying the negatively charged free carboxyl group, the ability to adsorb and exchange with the nutrient segregant is about 100 times that of the natural soil.
3)Soil conditioner
It has the properties of acid and alkali, and has excellent buffering capacity for acid and alkali soil.
4)Improve rooting and crop stress resistance
It has a natural growth-promoting effect on plant roots, stimulating the growth of root hairs and new roots, thereby enhancing the ability of the underground part of the plant to absorb nutrients.
5)Excellent chelating ability for medium and trace elements.
6)Make nutrients slow long terms released.
7)Improve crop immunity,quality and output
8)100% nature source and can nature degrade

Direction for use:
Add 5%-10% to all kinds of fertilizers

Packing:
25kg drum, 200L drum
