(NH₄)₂SO₄
Granular Ammonium Sulphate
A nitrogen-sulphur fertilizer for base application and top dressing. Sulphur in its water-soluble sulphate form is directly available for plant uptake. It is particularly effective for oilseed rape, winter wheat and brassicas, where sulphur deficiency limits the efficiency of nitrogen nutrition and may reduce yields. Sulphur deficiency is common on light and leached soils. Ammonium sulphate has a physiologically acidic effect and is therefore particularly suitable for neutral and alkaline soils. On acidic soils, its use should be combined with acidity monitoring and liming where required.
