Polyglutamic Acid

JINMAI® Polyglutamic Acid is an advanced biostimulant-based agricultural adjuvant formulated with 4.5% polyglutamic acid (PGA) and functional plant growth activators. Polyglutamic acid is a naturally derived polymer produced through microbial fermentation and is widely recognized for its excellent soil–plant interaction properties.

This innovative formulation enhances root activity and improves the efficiency of water and nutrient utilization in the rhizosphere. By forming a biological protective film on root surfaces, the product increases the contact area between roots and soil nutrients while helping retain moisture and fertilizers around the root zone.

Beyond root stimulation, JINMAI® Polyglutamic Acid also promotes balanced plant metabolism and hormone regulation, enabling crops to grow more vigorously and resist environmental stress. The biostimulant components further support sugar synthesis and fruit surface repair, resulting in improved fruit appearance, sweetness, and market value.

Technical Indicators

Key Features

Product Efficacy

⦁ Root Growth Stimulation and Protection

Polyglutamic acid promotes the formation of fine roots and root hairs, which significantly increases the plant’s capacity to absorb water and nutrients. At the same time, it forms a protective biofilm on root surfaces, helping protect roots from environmental stress and improving rhizosphere stability.

⦁ Water and Fertilizer Retention

PGA molecules have strong water-binding and nutrient-holding capacity. They help retain moisture and nutrients in the root zone, reducing leaching losses and improving fertilizer utilization efficiency.

⦁ Improved Stress Resistance

The biostimulant components help enhance plant metabolism by increasing proline accumulation and photosynthetic activity, enabling crops to better tolerate environmental stresses such as drought, salinity, and temperature fluctuations.

⦁ Fruit Quality and Surface Enhancement

The formula promotes sugar synthesis and metabolite transport within plants, improving fruit sweetness, uniformity, and appearance. It also helps repair minor fruit surface damage and supports better coloration.

⦁ Balanced Growth Regulation

By supporting natural hormone balance and cellular metabolism, JINMAI® Polyglutamic Acid encourages healthy vegetative growth and stable reproductive development, leading to improved yield potential.

FAQ

1. What is polyglutamic acid used for in agriculture?

Polyglutamic acid is used as a biostimulant to improve soil water retention, enhance fertilizer efficiency, and promote healthy root growth in crops.

2. How does polyglutamic acid help plants absorb nutrients?

Polyglutamic acid can bind water and mineral nutrients in the soil, keeping them available around the root zone and improving the efficiency of plant nutrient uptake.

3. Can this product help crops during drought conditions?

Yes. Polyglutamic acid improves soil moisture retention and supports plant metabolic activity, helping crops maintain growth under limited water conditions.

4. Does polyglutamic acid improve fruit quality?

The product promotes sugar synthesis and nutrient transport within plants, which can improve fruit sweetness, color uniformity, and overall market quality.

5. Is JINMAI® Polyglutamic Acid compatible with other fertilizers?

In most cases, it can be mixed with water-soluble fertilizers and many crop nutrition products. Compatibility testing is recommended before large-scale mixing.

6. At which growth stages should polyglutamic acid be applied?

It can be used throughout the crop cycle but is particularly effective during root development, vegetative growth, and fruit enlargement stages, when plants require efficient water and nutrient utilization.
