Ammonium Sulphate contains 21N 60SO3 2-5mm grade. Most soils, especially chalky or sandy soils, store very little sulphate, this is because sulphur is water soluble and easily leached. Sulphur is an essential nutrient which is required to help increase yields and achieve an improved quality of grain and OSR. Applications of Ammonium Sulphate are very cost effective solution.

- Wheat: Apply early March to early May
