With the growing demand for sustainable and high-efficiency agriculture, traditional compound fertilizers are facing key challenges such as low nutrient utilization and high nutrient loss.
Polyglutamic Acid (γ-PGA) compound fertilizer offers an advanced solution by improving nutrient efficiency, enhancing crop performance, and supporting soil health.
What is Polyglutamic Acid (γ-PGA)?
Polyglutamic Acid (γ-PGA) is a biodegradable, water-soluble biopolymer produced through microbial fermentation.
It is widely recognized for its:
- Strong water retention capacity
- Chelating ability for nutrients
- Controlled-release performance
- Environmental friendliness
These properties make γ-PGA an ideal functional additive in compound fertilizers.
Production Process of γ-PGA Compound Fertilizer
One of the key advantages of γ-PGA is its compatibility with existing fertilizer production lines.
1. Raw Material Preparation
Main materials include:
- Nitrogen source: Urea
- Phosphorus source: Monoammonium Phosphate (MAP)
- Potassium source: Potassium Chloride (MOP) or Potassium Sulfate (SOP)
- Functional additives: γ-PGA, microbial agents, controlled-release materials
All materials are precisely formulated to ensure optimal nutrient balance.
2. Mixing Process
Base NPK materials are thoroughly blended in a mixing system.
γ-PGA is introduced via a metering pump, ensuring uniform distribution throughout the mixture.
👉 A dedicated γ-PGA feeding tank can be easily integrated into existing systems.
3. Granulation
The mixed material is processed in a granulator under controlled conditions (temperature, humidity, and rotation speed).
This step ensures:
- Uniform granule size
- Improved physical strength
- Enhanced product appearance
4. Cooling and Solidification
Granules are cooled and solidified to achieve:
- Stable chemical structure
- Reduced caking risk
- Improved storage and transportation performance
Optimal Application of γ-PGA in Production
The addition stage of γ-PGA plays a critical role in product performance.
✔ Option 1: Mixing Stage Addition
- Added directly into the mixing tank
- Easy implementation
- Suitable for most production lines
✔ Option 2: Pre-Granulation Addition
- Added after mixing but before granulation
- Ensures better dispersion
- Maximizes functional performance
👉 Recommended dosage:
6–8 kg γ-PGA fermentation liquid per ton of fertilizer
Key Benefits of γ-PGA Compound Fertilizer
1. Improved Nutrient Use Efficiency
γ-PGA enhances nutrient retention through chelation and slow-release mechanisms.
- Reduces nutrient leaching
- Improves nutrient absorption
📈 Result:
Nutrient utilization increases from 30–35% to 40–50%
Average improvement: ~8%
2. Enhanced Root Development & Crop Growth
γ-PGA promotes:
- Stronger root systems
- Better nutrient uptake
- Increased stress resistance (drought, cold, salinity)
Visible crop improvements include:
- Thicker and greener leaves
- More developed roots
- Balanced plant growth
3. Soil Improvement
γ-PGA contributes to long-term soil health by:
- Improving water retention
- Enhancing soil aeration
- Reducing compaction
- Regulating soil pH
👉 Especially effective in:
- Arid regions
- Degraded soils
- Continuous cropping systems
4. Increased Yield and Profitability
By combining higher nutrient efficiency and improved soil conditions:
📊 Yield increase:
- Field crops: 10–25%
- Root crops: 30–60%+
