Protassium+® for Organic Production sulfate of potash (0-0-50-17S) has less than 1% chloride and the lowest salt index per unit of K2O of all major potassium sources. This ensures efficient water and nutrient uptake. The result is healthier plants and higher yields — whether conventionally or organically farmed.
