Sulfate of Potash (SOP) 0-0-50 is a common potassium fertilizer used in agriculture, providing the crop an essential macronutrient for plant health, promoting strong roots, improving disease resistance, and improving fruit and flower development. 0-0-50 contains sulfur, essential for amino acid synthesis, protein formation, and other vital plant functions. 0-0-50 has a neutral to slightly alkaline reaction in the soil and does not contribute to salinity. 0-0-50 has a lower solubility than Muriate of Potash (MOP), improving season-long potassium availability and reducing potassium losses with typical fall applications.
