pγ-PGA is water soluble, biodegradable, biocompatible, edible, and non-toxic to humans and the environment
γ-polyglutamic Acid (γ-PGA), was firstly found in the cells of Bacillus anthracis in the early 20th century, and it’s an important part of the cell capsule. As a biopolymer, it’s water-soluble, biodegradable and non-toxic. In 1942, researchers found that γ-PGA can be produced from some certain Bacillus by fermentation. Later, people also found γ-PGA in Japanese food-Natto, and at the same time, Bacillus natto was successfully extracted.
Application :
Used as multi-functional compound fertilizer, combined with NPK Fertilizer or used as drip irrigation, soaking seeds, root treatment, and foliar spray fertilizer alone.
Recommended usage:
1. Mixed with urea or NPK fertilizer: added ratio 0.5~1%/Ton（10%power）added ratio 0.3~0.5% (30% power).added ratio 1%-1.5%/Ton(7.5% liquid)
2. Use alone: 2~3kg/Ha.( 10%power) 1.0~1.5kg/Ha.(30%power).
7kg/Ha(7.5% liquid)
Application rates and Directions
>Base Fertilizer:
Use it about 7kgs( 7.5%liquid) for a unit of ha, then irrigate with clean water or muck water. Or irrigate amino acid together with water. Or fertilize with other compound fertilizers, broadcast application, hole application both are ok. It is applicable to all crops.
>Foliar Fertilizer:
Dilute it by 800-1000 times and spray directly. Also, it can spray by mixed with trace elements.
Use 200-700g for a unit of ha.(7.5%liquid)
>Compound Fertilizer & Irrigation Fertilizer:
It can be added to compound fertilizer by rate of 5-8%, improve the nutrient content of compound fertilizer, increases crops’ direct absorption.
