Controlled release fertilizers

What are CRFs?

Controlled release fertilizers (CRF) are a precision technology that shows environmental benefits in comparison to conventional fertilizers. CRFs release nutrients over a longer period of time thanks to an innovative coating technology. Developed to provide optimum nutrient levels throughout the crops’ entire growing cycle, our Controlled Release Fertilizers improve yields, reduce nutrient losses, and simplify fertilizer application.

The coated granules provide a continuous, controlled release of nutrients delivering the correct nutrition at the right time and at the levels crops require. With Controlled Release Fertilizers, you can be confident that young plants are not harmed or stressed from excess salt levels, and that mature plants have the nutrients they need to thrive through the whole growing cycle.

A simple, one-time application of one of ICL’s Controlled Release Fertilizers decreases nutrient losses, increases NUE, reduces the total mineral input required, and means fewer applications reducing costs. Crops benefit from nutrient availability throughout their growing cycle, delivering equal or greater yield from less mineral input, and enhanced crop uniformity thanks to the controlled nutrition. Find the CRF fertilizer that matches your crop and growing conditions.

What are its benefits?

1. Often only one application is required, as nutrients are released in a controlled manner over a longer period of time, giving the turf grass all nutrients it need, exactly at the right time.
2. The controlled release technology significantly reduces nutrient leaching to both soil and groundwater.
3. Greenkeepers and turf managers can benefit from high quality turf while lowering the environmental foot print in comparison to conventional fertilizers.
4. As such, CRFs are part of the solution in helping meet the future target to reduce nutrient losses in EU agriculture by 50 percent, as set out in the Farm to Fork Strategy, the Zero Pollution Action Plan, and EU Soil Strategy for 2030.

Application

CRFs are suitable for a wide range of plants, including:

• Ornamental plants and lawns for sustained growth.
• Agricultural crops to reduce the frequency of fertilizer application.
• Container-grown plants where nutrient leaching can be an issue.

CRFs can be used in any region but are especially beneficial in areas with high rainfall or irrigation practices that can cause nutrient leaching.
They are often applied at the beginning of the growing season to provide a consistent nutrient supply.
For specific recommendations on CRF use in India, it’s best to consult ICL agricultural services and agronomists.
