Polyglutamic acid powder, liquid, granules

Polyglutamic acid (γ-polyglutamic acid, abbreviated as PGA) is a water-soluble polyamino acid produced by 

microbial fermentation in nature. Its structure is a high molecular weight polymer where glutamic acid units 

form peptide bonds through α-amino and γ-carboxyl groups.

Properties: powder,liquid,granules

PH Value: 4.0-8.5

Packaging Specifications: 5Kg, 25Kg/bag or IBC drum

Technical Indicators: 3.50% /4.00% (water-based) / 25% (powder) fully water-soluble

Application

1. Strong water retention capacity; forms a thin film on the surface of plant root hairs, protecting them and acting as 

an optimal platform for the close contact between nutrients and water in the soil and root hairs, effectively improving 

the dissolution, storage, transport, and absorption of fertilizers. Prevents the precipitation of sulfate, phosphate, oxalate, 

and metal elements, allowing crops to more effectively absorb phosphorus, calcium, magnesium, and trace elements 

from the soil. Promotes root development and enhances disease resistance.

2. It has excellent buffering capacity against acids and alkalis, effectively balancing soil pH and preventing acidic soil 

caused by long-term use of chemical fertilizers.

3. It binds and precipitates toxic heavy metals, exhibiting excellent chelating effects on toxic heavy metals such as 

Pb²⁺, Cu²⁺, Cd²⁺, Cr³⁺, Al³⁺, and As⁴⁺.

4. It enhances plant disease resistance and stress tolerance, integrating plant nutrients and soil water components to 

strengthen resistance to symptoms caused by soil-borne plant pathogens.

5. It promotes increased yields, rapidly increasing the production of agricultural products such as tea, melons, fruits, 

and vegetables by 10-20%.

Usage and dosage：

1. Dilute the leaves 300-600 times or 30-50 grams per barrel (15kg-20kg water).

2. The seedling stage can be used alone, while the growth and fruiting stages can be combined with a large amount 

of elements.

3. Dilute 50-200 times and apply directly, or irrigate around the roots, with an interval of 5-7 days, or shorten or extend according to local fertilization habits.
