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. The release pattern closely matches the needs of turfgrass throughout its entire growth cycle.
Benefits of using CRFs are:
- 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.
- The controlled release technology significantly reduces nutrient leaching to both soil and groundwater.
- Greenkeepers and turf managers can benefit from high quality turf while lowering the environmental foot print in comparison to conventional fertilizers.
- 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.
