Medium-element water-soluble fertilizers are water-soluble fertilizers with calcium, magnesium, sulfur, and other essential medium-element elements (0.2%-1.0% dry weight) as their core components. They need to be used in conjunction with macro-elements such as nitrogen, phosphorus, and potassium to supplement crop nutrition and improve physiological disorders. Their characteristics include a full nitrate nitrogen formula and 100% water solubility, which can improve soil nutrient utilization efficiency, promote root development and plant growth, and improve soil physicochemical properties. They are hormone-free and residue-free environmentally friendly fertilizers.
Calcium fertilizers were widely used in agriculture early on. With the increasing intensive farming, calcium deficiency in soils has become more common, leading to increased demand for calcium fertilizers. In southern regions, due to changes in soil characteristics and crop types, magnesium deficiency is becoming increasingly prominent, while the demand for sulfur in some crops exceeds that for phosphorus. This fertilizer is designed for acidic and sandy soils prone to nutrient deficiencies, alleviating nutrient imbalances by supplementing medium-element elements and improving crop yield and quality. The product's application scope covers more than 30 kinds of crops, including fruit trees, vegetables, and field crops, and standardized application methods such as drip irrigation and fertigation have been formed.
