Potassium Sulfate (Sulfate of Potash; SOP) • K 2SO 4 • Grade: 48 to 53% K 2O 17 to 18% S • Rarely found in pure form in nature • Generally produced by manipulating potash ores to remove other materials • Valued when both K and S are needed for plant nutrition
Potassium Magnesium Sulfate (Langbeinite) • K 2SO 4�2MgSO 4 • Grade: 20 to 22% K 2O 21 to 22% S 10 to 11% Mg • Distinct geologic material found in only a few places in the world • Generally produced by manipulating potash ores to remove other materials • Valued when both K, S, and Mg are needed for plant nutrition
