Controlled-release fertilizers

Advanced polymer-coated CRFs that release nutrients gradually, matching the plant's growth cycle instead of all at once.

Controlled nutrition for better crop performance

Controlled-release fertilizers are designed to provide crops with a consistent and efficient nutrient supply over a defined period. By controlling nutrient release, controlled-release technology helps align nutrient availability with crop demand, supporting healthy growth, strong root development and more efficient fertilizer use across a wide range of crops and growing systems.

How controlled-release fertilizer works

Our unique process encapsulates nutrients in an organic polymer coating that releases them precisely over time.

Encapsulation

Micronutrients encapsulated in organic polymer coating.

Water absorption

Water penetrates coating, initiating nutrient release.

Nutrient dissolution

Nutrients dissolve into concentrated formulation.

Controlled-Release

Steady nutrient release over 3 to 18 months.

Release curve simulator

Controlled-release fertilizer is designed to deliver nutrients gradually, in line with the plant's growth cycle. Unlike conventional fertilizers that release nutrients all at once, CRFs feature a polymer coating that controls nutrient release based on temperature, moisture, and soil conditions. This ensures optimal nutrient availability when plants need it most, reducing waste and maximizing crop performance.

Select Specific Crop:

Crop Growth Cycle: 6 Months

CRF Release Time: 6 Months

Soil Temperature: 25°C

* Note: The absolute height of the release curve relative to crop demand is highly dependent on the total volume (application rate) of the fertilizer applied. This model assumes an optimal application rate.

Why Choose Controlled-Release Fertilizers?

Gradual nutrient release improves efficiency, reduces waste, and simplifies farm management.

More efficient nutrient use

Gradual release improves nutrient use efficiency and supports sustainable crop production.

Reduced leaching and volatilization

Polymer coating minimizes environmental losses through leaching and volatilization.

Less frequent applications

Fewer applications needed, saving time and labor in professional and large-scale systems.

Controlled-release fertilizer solutions for all crops

Tailored controlled-release formulations for every crop type and growing system.
