Gaia Green Langbeinite (22%-K 18%-Mg 22%-S), also known as Sul-Po-Mag or K-Mag, occurs as a natural mineral. This soluble mineral fertilizer will not alter soil pH. It is a natural source of potassium, sulphur, and magnesium in a fast acting form. Potassium aids in the formation of carbohydrates (sugars and starches), improves quality of fruits and vegetables, and stiffens plant tissue by balancing resistance to disease and cold weather. Magnesium is the key element in chlorophyll formation. Sulphur is vital to plant life, it is a component of amino acids which form proteins when hooked together. The combination of potassium, magnesium, and sulphur make Langbeinite an important fertilizer.
