γ-PGA has hydrophilic group -carboxyl which can maintain soil moisture content, improve soil flushing and gap, improve sandy soil, and promoting fertilizer and water preserving capacity of soil.
Some study results,
When γ-PGA made resin was used to deal with seeds, which can increase the germination rate of seeds in drought and water-deficient areas.
Use γ-PGA to directly mix or soak, which can promote the height of the wheat plant and increase the seedling rate.
Simulation of 5.0, 10.0, and 16.5mm rainfall, add 150, 300, and 500ml γ-PGA water immersion to the dry soil, which can increase seedlings and extend the depth of the root system.
