Controlled Release Fertiliser is designed to release nitrogen in a defined and predictable manner, to assist with matching the supply of nitrogen with the demands of your crop.
Reducing nitrogen volitsation can also save you money on nitrogen losses that can escape as ammonia gas, or through leaching nitrate during wet weather events or irrigation.
Controlled release urea can also increase crop yields by providing better access to ammonium nitrogen throughout the season.
Coated urea can also provide flexibility with application:
- There’s low rainfall – and you can’t guarantee 10-15mm of rainfall within within 24-48 hours of applying the urea
- Top dressing the urea without incorporation into the soil, to a depth of greater than 5cm
- The soil surface is drying out
- Conditions are relatively warm, or windy
- There’s a high level of crop residue or litter
