About this product
Ammonium Sulphate AS 21 Select is a straight nitrogen and sulphur fertiliser supplying 21% ammoniacal nitrogen and 24% sulphur (60% SO₃) in a free-flowing granular form. The stable ammonium nitrogen resists leaching while water-soluble sulphate supports protein synthesis and oil formation. It suits winter and spring cereals, oilseed rape, maize, sugar beet, potato and grassland, applied pre-sowing or as an early spring top dressing at 80–250 kg/ha.
