AOLANSU Slow Release Compound Fertilizer is a controlled-release NPK fertilizer designed for modern agriculture, providing continuous nutrition throughout the crop growth cycle. Compared with traditional quick-release fertilizers, it reduces nutrient loss, improves fertilizer utilization efficiency, and helps farmers achieve stable crop growth with fewer fertilization operations.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd., a professional fertilizer manufacturer in China, this slow release compound fertilizer is widely used for field crops, vegetables, fruit trees, greenhouse cultivation and commercial agricultural projects. Customized NPK formulas are available according to different crops, soil conditions and regional farming requirements.
AOLANSU Slow Release Compound Fertilizer contains balanced Nitrogen (N), Phosphorus (P₂O₅), Potassium (K₂O), as well as essential secondary and trace elements including Calcium, Magnesium, Sulfur and Zinc. The scientific nutrient ratio provides comprehensive nutrition for plant growth from early development to harvest.
The fertilizer is manufactured into uniform granules with excellent hardness, flowability and storage stability. The granules are suitable for both manual application and mechanized fertilizer spreading, ensuring consistent nutrient distribution in agricultural fields.
Each fertilizer granule is coated with a controlled-release layer. After being applied into soil, water gradually penetrates the coating and dissolves the nutrients inside. The nutrients then slowly diffuse through the coating, providing a stable nutrient supply throughout the crop growth period.
This technology helps avoid excessive nutrient release after heavy rainfall or irrigation and supports more balanced plant growth. It is especially suitable for areas where fertilizer efficiency and labor reduction are important factors.
| Comparison | Slow Release Compound Fertilizer | Traditional Compound Fertilizer |
| Nutrient Release | Gradual and controlled release | Fast nutrient release |
| Fertilization Frequency | Fewer applications required | Usually requires additional top dressing |
| Nutrient Loss | Lower risk of leaching and volatilization | Higher nutrient loss possibility |
| Labor Cost | Reduced field operation cost | Higher application frequency |
AOLANSU Slow Release Compound Fertilizer adopts advanced granulation and coating technology. The production process includes raw material inspection, automatic mixing, granulation, drying, screening, coating, cooling and laboratory testing.
Through strict process control, each fertilizer granule maintains consistent nutrient distribution and coating thickness, ensuring stable release performance and reliable agricultural application results.
AOLANSU Slow Release Compound Fertilizer is developed for different agricultural environments and planting systems. It provides a stable nutrient supply for large-scale farming, greenhouse cultivation, orchards and commercial crop production.
Suitable for major grain crops including rice, wheat and corn. The controlled nutrient release helps improve root development, promote stronger plant growth and support stable yield performance.
Suitable for tomatoes, peppers, cucumbers and other greenhouse vegetables. The balanced nutrient supply helps improve plant growth, flowering performance and fruit development while reducing frequent fertilization operations.
Suitable for apples, grapes, tea, cotton and other economic crops. Long-lasting nutrient supply helps maintain plant nutrition during important growth periods.
In greenhouse tomato cultivation projects, AOLANSU Slow Release Compound Fertilizer was applied as a basal fertilizer instead of multiple conventional fertilization operations. Growers observed stronger plant growth, improved nutrient stability and reduced field management workload.
The controlled-release fertilizer program helped maintain a more stable nutrient environment compared with traditional fertilization methods, especially during flowering and fruit development stages.
For winter wheat production, slow release compound fertilizer provides continuous nitrogen, phosphorus and potassium nutrition from early growth to grain filling stages. Farmers can reduce additional fertilization operations while maintaining healthy crop development.
All raw materials are inspected before production. Heavy metals, moisture content and nutrient composition are controlled according to fertilizer quality requirements.
The manufacturing process integrates automatic batching, mixing, granulation, coating and drying technologies to ensure uniform granule size and stable nutrient distribution.
Every production batch is tested for total nutrient content, moisture, particle size and controlled-release performance. Products are shipped only after passing quality inspection.
Standard packaging includes:
Customized packaging, customer labels and OEM services are available according to market requirements.

Slow Release Compound Fertilizer controls the nutrient release speed through coating technology, allowing crops to absorb nutrients gradually throughout the growth cycle. Traditional fertilizers usually release nutrients quickly, which may result in nutrient loss after rainfall or irrigation.
It is suitable for rice, wheat, corn, vegetables, fruit trees, greenhouse crops, tea, cotton and many other agricultural crops. The fertilizer formula can be adjusted according to different crop nutrient requirements.
The standard nutrient release period is approximately 3-6 months. According to crop growth cycles and local climate conditions, customized release periods can also be provided.
