Ultra Fines Sulfate of Potash is OMRI listed and gives 52% potash (K2O) and 18% sulfate (SO4). It is fine grade, minus 200 mesh, for easy measure and application.
Both potassium and sulfur are vital to many plant functions. Potassium improves plant yield, quality, disease resistance, tolerance to pests and water stress, winter hardiness, nitrogen use, and efficient use of other nutrients. Sulfur is essential for production of protein, chlorophyll, enzymes, vitamins, fat and oil, carbohydrates, seeds, and the efficient use of phosphorus and nitrogen. Sulfur deficiencies appear on younger leaves; in forages, it is associated with "hidden hunger" and can seriously affect animal performance and health.
Application rates depend on soil analysis. Ultra Fines Sulfate of Potash is a fertigation solution - you can apply just the right amount needed through irrigation directly to the root zone.
