Langbeinite

Langbeinite, also known as sulfate of potash-magnesia, K-Mag, Trio, or Sul-Po-Mag, is a naturally occurring potassium magnesium sulfate mineral which formed when ancient oceans in New Mexico evaporated and left behind complex salt compounds.

Langbeinite is a potent fertilizer that works well as a top dressing during mid-bloom or mixed into soil before transplant. Potassium and magnesium are essential for the production of terpenes, natural oil compounds that carry scent and flavor. Soil with ample supplies of potassium and magnesium will grow strong plants with large, delicious fruit.

OMRI listed. Organic and natural granulated mineral.
