Ag K Sol

Ag K Sol (Sulphate of Potash) is a specialty fertiliser in white powder form, suitable as substitution to other source of potassium fertiliser in the market. Ag K Sol is ideal for all crops and all growth stages, or whenever high K input is needed. It also contains low chloride and negligible heavy metal content (≤2ppm), thus, suitable to mix with other fertilisers, except those containing high level of calcium. Due to its negligible salt index, it is suitable as fertilisation programs for crops growing in high salinity soil. In alkaline soils, the application of Ag K Sol can reduce the pH at root zone and induce better absorption of phosphorus and micronutrients.
