Controlled Release Fertilisers

What are Controlled Release Fertilisers?

Controlled Release Fertilisers (CRFs) are an advanced range of products that release nutrients over a specific timescale, in a controlled way. This
ensures nutrient availability matches the crop’s requirements more effectively than standard fertilisers, leading to higher Nitrogen Use Efficiency (NUE) and reduced nutrient loss.

Developed to provide optimum nutrient levels throughout the crops’ entire growing cycle, our Controlled Release Fertilisers (CRFs) improve yields, reduce nutrient losses, and simplify fertiliser 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 Fertilisers, 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.

What are the benefits of using Controlled Release Fertilisers?

By providing consistent and predictable nutrient release, CRFs bring a range of benefits to all crops. Trials conducted with root vegetable, brassica, and allium growers show yield uplifts from 8% to 16% versus standard farm practice.

• Higher Nitrogen Use Efficiency versus other N fertilisers
• Increase yields per tonne of Nitrogen input, or maintain yield with
  less fertiliser
• Reduce costs, through less fertiliser applications and a reduction in
  farm traffic and soil compaction
• Produce better quality crops – greater uniformity and colour leading
  to more marketable product
•  Reduce your environmental impact

With CRF, the nutrient supply matches the demand of the plants to give both optimal growth and nutrient efficiency

A simple, one-time application of one of ICL’s Controlled Release Fertilisers 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.
