Agricultural Grade Polyglutamic Acid Powder 25%

What is Agricultural Grade Polyglutamic Acid?

Agricultural grade polyglutamic acid is generally low molecular weight polyglutamic acid with molecular weight ≤ 10000 Da and content ≥ 25%. Agricultural grade γ-polyglutamic acid has a large number of hydrogen bonds between the chains, so it has good solubility. A large number of peptide bonds exist in the main chain of this polyglutamic acid, which can be degraded into non-toxic short peptides and amino acid monomers, so it has excellent biocompatibility and biodegradability. Agricultural grade polyglutamic acid powder also has good water retention, because it has a large number of free carboxyl groups on the main chain, so it has strong water absorption and moisture retention.

In the process of promoting plant growth, the role of agricultural-grade polyglutamic acid is mainly divided into three stages. Firstly, the polyglutamic acid applied to the soil can be wrapped around the fertilizer due to its unique macromolecular structure, which can play the role of water retention and reduce the loss of water and fertilizer, and at the same time, it can chelate the trace elements in the soil and improve the soil structure.

With the natural degradation of the macromolecular structure in the soil into peptides and small peptides, it has a biostimulating effect, which can greatly increase the efficiency of plant photosynthesis and improve resistance performance. Ultimately, polyglutamic acid is naturally degraded into monomer type, which is directly absorbed by crops as amino acid nutrition. Under the synergistic effect of the three processes, the purpose of soil improvement and crop yield enhancement is finally achieved.

Agricultural grade polyglutamic acid powder 25% supplied by Green Spring Technology is a class of polyamino acid made by the polymerisation of glutamic acid monomers through phthalamide bonding, which is a kind of biopolymers, amino acid prepared by microbial fermentation, with the advantages of super adsorption and non-toxicity. Green Spring has a systematic quality management system, which strictly implements the quality management system and organises production in accordance with ISO, HACCP and other quality standards. We have passed Halal, Kosher, COSMOS, BRC, IFS, FDA, ISO and many other certifications. We can provide authoritative third-party test reports.

Benefits:

Superb Water Retention

Polyglutamic acid molecule contains more than 1000 super hydrophilic groups (-COOH). It can fully retain water in the soil, improve the bulkiness and porosity of sticky soil, and improve the fertiliser and water retention capacity of sandy soil. When used in flooded soil, it forms a film on the surface of plant root hairs to protect them. It effectively improves fertiliser dissolution, storage, transport and absorption.

Especially in arid and semi-arid areas where water is scarce or scarce, or in areas where drip irrigation and water-fertiliser integration are applied, the use of polyglutamic acid powder can greatly improve the utilisation of water and fertiliser. Keep the water and nutrients effectively distributed around the root system, more absorbed and utilised by the plants, and reduce the water and fertiliser loss caused by evaporation, seepage and so on.

Promote the Absorption of Phosphate Fertilizer and Trace Elements

Polyglutamic acid has multi-anionic properties, which can effectively prevent sulfate, phosphate, oxalate, carbonate, and other ions from combining with calcium ions, magnesium ions and trace elements. It avoids the production of low solubility salts and precipitation and therefore promotes the absorption and utilisation of nutrients such as trace elements and phosphate fertilisers. It also improves the exchange capacity of cations in the soil and temporarily stores and adsorbs cations. For example, calcium ions, magnesium ions and other trace elements such as iron, manganese, copper, zinc and other cations, and then slowly released into the soil to replenish.

Adjusting the pH of the Soil

Polyglutamic acid powder has excellent buffering ability for acids and alkalis, and can effectively balance the soil pH value. Avoid acidic soil and soil fragmentation caused by long-term use of chemical fertilizers. Taking the Jiaodong Peninsula as an example, many apple orchards experience soil acidification. After applying about 1 liter of polyglutamic acid fermentation broth per acre, it was observed over time that polyglutamic acid can significantly increase the pH value of acidic soil by 1-2 times. It improves fruit tree diseases such as bitter pimples caused by acidification, while also improving fruit quality. In addition, polyglutamic acid powder has a good regulatory effect on salinization caused by seawater backflow and secondary acidification caused by excessive use of chemical fertilizers.

Enhance Plant Resistance

Polyglutamic acid improves the content of proline in plants, increases the metabolic capacity of crop cells, and improves the efficiency of photosynthesis and the resistance of plants.

Protecting Plant Roots

Polyglutamic acid powder can stimulate the growth of root hairs and new roots, and form a film on the surface of root hairs. It not only protects the root hairs, but also increases the contact area between the nutrients and water in the soil and the root hairs, retaining water and fertiliser and increasing the supply of effective nutrients.

Enhance Crop Resistance to Disease and Adversity

Polyglutamic acid powder itself has a natural promotional effect on plant roots, stimulating the new growth of root hairs and root growth, thus enhancing the ability of the underground part of the plant to absorb nutrients, effectively ensuring the normal absorption of water and nutrients in the event of drought, waterlogging, and low temperatures and other adversities, and buffering drought, waterlogging, and cold and other adversities on the plant root system caused by the damage.

Applications:

In the Agriculture Field:

Polyglutamic acid in agriculture can substantially improve crop water absorption, increase soil water retention, permeability, and improve the utilisation of nitrogen fertiliser.

In Cosmetics:

Polyglutamic acid powder as a cosmetic raw material, can beautify and whiten the skin all-round moisturising, gently inhibit tyrosinase activity as well as inhibit the production of melanin, which can deeply moisturise and lighten the skin.

In the Food Field:

The food field mainly applies polyglutamic acid powder with a molecular weight of about 200,000, which is used as a preservative and additive.
