Polyglutamic acid (PGA) granule fertilizer is a granulated fully water-soluble fertilizer extracted from plants and produced by microbial and enzymatic fermentation technology. It is rich in free amino acids and microelements.

This fertilizer is suitable for the production of water-soluble fertilizers, organic-inorganic compound fertilizers. And is applicable in various scenarios such as drip irrigation and machine fertilization.

Role in Fertilization and Agriculture:

1. Water Retention and Soil Moisture Management:

PGA can improve the water-holding capacity of soil, reducing the frequency of irrigation. This is particularly valuable in areas experiencing water scarcity or drought conditions.

It acts as a natural superabsorbent, helping the soil retain moisture for longer periods.

2. Enhancing Nutrient Availability:

Polyglutamic acid can help improve the uptake of nutrients in plants by acting as a chelating agent, binding with essential minerals and making them more available to plant roots.

This can lead to better growth and yield, especially in nutrient-poor soils.

3. Soil Structure Improvement:

PGA can enhance soil structure by promoting aggregation.

This leads to better aeration and root penetration, facilitating healthier plant growth.

4. Biodegradable and Eco-friendly:

Polyglutamic acid is a biodegradable, non-toxic material, making it environmentally friendly compared to many synthetic fertilizers.

This makes it a desirable alternative in organic farming or sustainable agriculture.

5. Microbial Activity Enhancement:

Polyglutamic acid can stimulate beneficial microbial activity in the soil, which is crucial for soil health.

These microbes help break down organic matter and cycle nutrients, promoting soil fertility.

Polyglutamic acid (PGA) granule fertilizer Application in Agriculture:

• Used as synergist of chemical fertilizer

Main material	Additive amount	Features	Adding method
Compound fertilizer (tower granulation)	20-40 kg	Improve the ability of salt and alkali tolerance, fertilizer efficiency, promote crop growth, improve photosynthesis.	Spray on hot after granulation Pellet surface, cool package
Urea	15-25 kg	Promote nitrogen absorption, improve urea utilization, promote seedling growth, chlorophyll synthesis.
Diammonium phosphate	20-30kg	Improve the absorption and utilization of phosphorus, promote seed germination, strengthen and root development.
Foliar fertilizer (liquid)	30-50kg	Improve the absorption and utilization of potassium in crops, promote photosynthesis, increase the content of cellulose in plants, promote root growth, and enhance resistance.	Add directly and mix well
Foliar fertilizer (powder)	20-30kg	Improve the absorption and utilization of potassium in crops, promote photosynthesis, increase the content of cellulose in plants, promote root growth, and enhance resistance.
Liquid fertilizer	40-60kg	Promote the absorption of key elements and the synthesis of chlorophyll, improve the resistance of crops, promote early flowering and improve quality.	Add directly to the liquid fertilizer and mix Mix well
Drip irrigation fertilizer (powder)	20-40 kg	Slow down soil acidification and salinization, adjust soil pH, promote root growth, improve crop disease resistance, stable yield and increase income.
Water soluble fertilizer with medium and trace elements	20-40 kg	Improve activity, coloring increase, early, increase quality, protect fruit, disease resistance, stress resistance, improve quality and increase yield.	Powder additive is added with the raw material In, mix evenly, and the liquid additive is sprayed on the surface of the particle
Potassium dihydrogen phosphate	15-25 kg	Improve the utilization of potassium, increase crop resistance, increase crop yield and quality.

• As a Soil Conditioner:

PGA can be applied directly to soil to improve water retention, nutrient availability, and soil texture. It’s often used in combination with other organic or synthetic fertilizers to improve their performance.

• Foliar Spray:

In some cases, polyglutamic acid can be used as a foliar spray to provide nutrients directly to the plant leaves.

Benefits of Using Polyglutamic acid (PGA) granule fertilizer in Fertilization:

• Reduced Fertilizer Loss:

By enhancing nutrient retention in the soil, PGA helps reduce the leaching of fertilizers into groundwater or runoff, reducing environmental pollution.

• Improved Crop Yield:

The better nutrient and water management enabled by PGA can lead to increased crop productivity.

• Sustainability:

As a biodegradable and natural substance, PGA supports sustainable farming practices by reducing dependence on synthetic chemicals.
