Sul-Po-Mag K-Mag Standard Mini-Granule Langbeinite — 50 lb

Sul-Po-Mag (K-Mag) is a naturally mined langbeinite fertilizer delivering 22% K₂O, 10.8% magnesium (Mg), and 22% sulfur (S) in a standard mini-granule form. Each granule contains all three nutrients in the same ratio, ensuring uniform nutrient distribution with every application. With extremely low chloride content (less than 1.0–3.0% Cl depending on grade) and a neutral pH, Sul-Po-Mag is safe for chloride-sensitive crops and compatible with organic production systems.

OMRI Listed and approved for organic farming. Produced by Intrepid Potash from naturally occurring langbeinite deposits in New Mexico.
