Dora PolyGlutamic Acid (γ-PGA) is produced through fermentation by Bacillus subtilis. γ-PGA is a homo-polymer of glutamic acid, it has excellent hydrophilic and high water absorption capacity. It can chelate trace elements in the soil, induce endogenous hormones and enhance plant resistance ability. Dora PolyGlutamic Acid also contains microbes, NPK, glucose, organic matter, etc. It is a great fertilizer synergist and a natural, organic, and environment-friendly plant nutrition enhancer.
Mechanism of PolyGlutamic Acid
Loss on Drying

Effect of PolyGlutamic Acid (γ-PGA)
1. Use as fertilizer synergist
The utilization rate of nitrogen fertilizer is increased by 50-60%, the utilization rate of phosphorus fertilizer is increased by more than 5%, and the utilization rate of potassium is increased by 15-20%. About 20% of chemical fertilizers can be saved per hectare.
It enriches nitrogen, phosphorus and potassium, and also collects medium and micronutrients such as calcium and magnesium to meet the various needs of crops and improve the supply capacity of soil nutrients.
PolyGlutamic Acid (γ-PGA) can inhibit the loss of fertilizer and water, prolong the release time of fertilizer nutrients, reduce the frequency of topdressing, save human resources, and reduce pollution caused by excessive fertilization.
2. Soil remediation
- Promote the absorption of phosphate fertilizer and medium and trace elements.
- Balance soil pH Value.
- Chelate toxic heavy metals in soil.
- Helps the soil build a stable structure to store more water and nutrients.
1. Use on Cabbage - Thicker leaves
2. Use on Potato - Increase Yields
