γ-polyglutamic acid is a water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. It plays an important role in protein metabolism in plants and participates in many important chemical reactions.
What is γ-polyglutamic acid(γ-PGA)?
γ-polyglutamic acid is a kind of homopolymeric amino acid formed by the polymerization of glutamic acid monomer through amide bond. It is a kind of biopolymer material, the third generation amino acid prepared by fermentation from raw materials such as monosodium glutamate and glucose. It has the advantages of adsorption and so on. Adding it to compound fertilizer, compound fertilizer, organic fertilizer, urea, water-soluble fertilizer and other fertilizers has multiple functions such as reducing fertilizer nutrient loss, improving fertilizer utilization rate, and regulating plant growth. It is a new generation of fertilizer synergist.
It has significant application effects on rice, wheat, corn, peanut, sweet potato, yam, vegetables, fruit trees and other plants, and can significantly increase crop yield by 10%-25%, and root crops by more than 30%.
γ-polyglutamic acid will form a protective film on the roots of plants to protect the root hairs of plants. In addition, it can transport nutrients and water in the soil to plants. It can also absorb the nutrients in the fertilizer and improve the conversion rate and utilization rate of the fertilizer. It also promotes the development of plant roots and enhances plant disease resistance.
What does γ-PGA do to plants?
γ-polyglutamic acid has a certain protective effect on the root system of plants. It will form a protective film on the roots of plants to protect the root hairs of plants. In addition, γ-polyglutamic acid can better absorb soil nutrients and water, and transport them to the plants, so that the plants grow better.
γ-polyglutamic acid can also absorb nutrients in fertilizers and deliver them to plants, improving the conversion rate and utilization rate of fertilizers. The composition in the soil is relatively complex, but polyglutamic acid can prevent the precipitation caused by the chemical reaction between certain acid radical ions and metal elements, promote the development of plant roots, and enhance the disease resistance of plants.
Long-term use of chemical fertilizers will cause the soil to be weakly acidic. But γ-polyglutamic acid can well adjust the properties of the soil. It can also combine toxic heavy metals, filter them, integrate plant nutrients and active ingredients in the soil, and enhance plant disease resistance. In addition, polyglutamic acid can also rapidly increase the production of agricultural products such as fruits and vegetables.
γ-polyglutamic acid can promote the absorption and utilization of nutrients such as medium and trace elements and phosphate fertilizers. In addition, polyglutamic acid can also improve the exchange capacity of cations in the soil, and temporarily store and adsorb cations, such as calcium ions, magnesium ions, etc. Elements and other trace elements are slowly added to the soil to supplement.
