Is this product right for your needs?
Choose sulphur-containing complexes when SO₃ (and MgO on selected grades) should arrive in the same granule as N, P and K.
- SO₃ levels from 5% to 17% depending on grade
- MgO included on NPK 18-6-18 + 5SO₃ + 2MgO
- NP + S options when potash is separate
- Uniform granules for even nutrient placement
