Poly-γ-glutamic acid (γ-PGA) is a naturally occurring biopolymer with excellent water retention, biodegradability, and soil improvement properties. As a biostimulant, it enhances nutrient uptake, improves soil structure, and boosts crop resistance to drought and stress.
Key Benefits
Water Retention
γ-PGA can absorb up to 5,000 times its own weight in water, significantly improving soil moisture retention.
Enhanced Nutrient Uptake
Chelates soil minerals and micronutrients, making them more bioavailable for plant absorption.
Soil Microbiome Support
Promotes beneficial soil microorganism activity, improving overall soil health and fertility.
Drought Resistance
Helps crops withstand water stress, particularly valuable in arid and semi-arid agricultural regions.
