CRF in Paddy Field

Controlled Release Fertilizer (CRF) offers significant benefits for paddy fields by providing a consistent supply of nutrients throughout the growing season. The polymer-coated urea slowly releases nutrients, ensuring that the paddy plants receive essential elements over time, leading to improved crop yields and healthier plants.

By reducing the need for frequent fertilizer applications, CRF not only saves time but also minimizes nutrient loss through leaching. This technology ensures that the paddy plants have continuous access to nutrients, ultimately enhancing their growth and overall productivity.

A controlled release fertilizer is a granular fertilizer wrapped in a thin polymer coating. Water passes through the coating,
dissolves the nutrients inside, and those nutrients then move out slowly through the same semi-permeable layer. Instead of anlarge dose that is available immediately, the plant receives a steady supply over a set period.

The result is fewer applications and less waste. A conventional fertilizer releases everything as soon as it dissolves, so a heavy rain can carry a large share of it past the root zone before the plant has used it. A controlled release fertilizer is still releasingbmonths later, which is why it suits young palms, nurseries and replanting, where the plant needs a long, even supply and where re-applying is expensive.
