Potassium Schoenite is a premium water-soluble, chloride-free fertilizer that provides two essential nutrients—Potassium (K) and Magnesium (Mg)—in readily available forms. It plays a crucial role in plant metabolism, improving yield quality, crop strength, and resistance to environmental stress. This naturally occurring mineral is ideal for use in crops that are sensitive to chloride and sodium, offering a balanced nutrient profile for effective plant nutrition.
In addition to Potassium and Magnesium, Potassium Schoenite also supplies Sulphur (S), which aids in protein synthesis and enzyme activation. With a low level of water-insoluble matter (0.5% max), high solubility (≥30% at 30°C), and minimal chloride content, it ensures efficient nutrient uptake and compatibility with all fertigation and foliar application systems. This makes it highly suitable for use in modern agriculture and horticulture.
