K-Mag 0-0-22. A unique 3-in-1 combination of potassium, magnesium, and sulfur. K-Mag is a naturally occurring source of these three vital plant nutrients. Potassium is essential for high quality fruit, Magnesium is required for the synthesis of chlorophyll and Sulfur is needed for enzyme activation.

K-mag is nature's unique and perfectly balanced source of K, Mg and S. Known as Langbeinite, potassium magnesium sulfate, or double sulfate of potash, K-mag is sourced from natural ore beds deep beneath the earth's surface, where an isolated lake of ocean water once existed.

With a unique blend of potassium, magnesium, and sulfur in every granule, K-Mag allows for balanced crop nutrition across every acre. Certain crops are sensitive to high levels of chloride.
