Fermentation-Derived Liquid Potassium for Organic Production

Sigma K-Ferm uses proprietary fermentation technology to produce low molecular weight organic acids, ensuring rapid potassium uptake and enhanced plant vitality. Unlike conventional potassium sources, the fermentation process breaks potassium into highly bioavailable forms that move quickly into the plant — improving nutrient assimilation, supporting healthier yields, and building stronger, more resilient turfgrass.

Approved for organic production. Compatible with liquid fertilizers and soil amendments. Use on a wide range of crops including turfgrass, vegetables, and specialty crop.
