Carbon-complexed with Micro Carbon Technology®, OMRI-Listed Fertilgold® K-6 is an organic potassium product derived from potassium sulphate (6.0% KO and 2.0% sulfur, with 4.0% organic matter) that effectively maximizes potassium uptake by plants. Potassium promotes internal cellular strength for fruit development and maturity, and it helps to regulate the movement of water and nutrients within the plant.
