Why Protected Urea for Grasslands?
Protected Urea has lower nitrous oxide (N2O) emissions compared to CAN & lower ammonia (NH3) losses compared to urea. Never has pressure for agriculture to reduce these losses been greater and protected urea is a practical cost effective solution.
Considerations when spreading Protected Urea?
- Set up & calibrate fertiliser spreader correctly, check bout width due to lower bulk density. If you can spread urea you can spread protected urea
- Fertiliser with 80% of granules 2 to 4mm in size
When to apply Protected Urea?
- Use protected urea as main straight N / N & S source
- Protected urea can be applied in spring, summer & autumn (within spreading period dates)
