AgroPha PGA Polyglutamic Acid Liquid
(AGROPHA PGA)
AgroPha PGA: premium Ihumate gamma-polyglutamic acid liquid for water conservation, nutrient efficiency and root-zone stress management
Gamma-polyglutamic acid (γ-PGA) is a high-molecular-weight anionic polypeptide polymer produced by microbial fermentation. AgroPha PGA is a yellow liquid with γ-PGA >7%, organic matter >100 g/L and a density of 1.1 g/mL. Its hydrophilic polymer network supports root-zone water retention, nutrient chelation and controlled nutrient-release programs, while contributing to soil-structure and pH-buffering management.
Agronomic value: designed for saline-alkali soils, sandy soils, compacted soils and programs seeking more efficient use of water and fertilizer. Used alongside irrigation, fertilization and soil monitoring, it can support a more stable root-zone environment, root development and recovery from salinity, drought or waterlogging stress. Yield, nutrient-efficiency and stress outcomes depend on soil, crop, water quality, fertilizer practice and application program, and require local validation.
The Ihumate advantage: professional biostimulant and soil-management expertise, batch quality management, technical documents, formulation-compatibility guidance, export support and OEM/ODM service.

Frequently Asked Questions
1
What are the key specifications?
Yellow liquid; gamma-polyglutamic acid (γ-PGA) >7%; organic matter >100 g/L; density 1.1 g/mL. The final specification follows the batch COA, TDS and contract.
2
How does gamma-PGA support agriculture?
Its hydrophilic polymer structure can support root-zone water retention and nutrient-release management, while anionic groups can participate in nutrient chelation or adsorption. Use it within a sound irrigation, fertilization and soil-monitoring program.
3
Which soils are suitable?
It is especially relevant to saline-alkali soils, sandy soils, low water- or nutrient-holding soils, and root-zone programs focused on fertilizer-use efficiency.
4
What is the application rate?
No universal rate has been supplied for this product. Ihumate's technical team should set the crop- and site-specific rate after reviewing soil EC/pH, irrigation, water quality and fertilizer inputs; test compatibility and performance first.
5
Does printed packaging information represent the product?
No. The image is a packaging-format example only. Guaranteed analysis, net content, label and regulatory text follow the TDS, COA, contract and destination-market requirements.

Application & Dosage: AgroPha PGA Polyglutamic Acid Liquid
For water conservation, nutrient-use and root-zone stress-management programs. Use alongside irrigation planning, fertilization, soil EC/pH monitoring and local crop-management practices; conduct compatibility testing before first use or tank mixing.
Water and Nutrient Efficiency
- Irrigation and Fertigation Programs:Use as part of a defined root-zone water and nutrient strategy. Set rate and frequency according to crop, soil and irrigation conditions.
- Fertilizer-Formulation Enhancement:For premium fertigation, liquid-fertilizer and biostimulant programs; validate pH, stability, storage and compatibility with fertilizers and crop inputs before commercial formulation.
Saline and Sandy Soil Management
- Salinity and Moisture-Stress Programs:Pair with leaching, irrigation and base-fertilizer management to support root-zone moisture and structure. It does not replace soil testing or comprehensive saline-soil remediation.
- Ihumate OEM/ODM:Batch quality management, TDS/COA, compatibility guidance, export documents and OEM/ODM packaging are available.
