Description
potassium-based fertilizer that is produced by evaporating brine from potash deposits. MOP is the most widely used potassium fertilizer in the world, as it provides a high concentration of potassium and is relatively cheap and stable. MOP can be applied to the soil before or during planting or as a top dressing. MOP improves the water use efficiency and stress tolerance of the plants, but it also can cause soil salinity and chloride toxicity.
