Magnesium fertilizer has the function of increasing crop yield and improving crop quality. Magnesium sulfate is the main variety of magnesium fertilizer. Magnesium sulfate contains both magnesium and sulfur nutrients, which can significantly improve the yield and quality of crops. Magnesium sulfate is suitable for all crops and all kinds of soil conditions. It has excellent application performance, wide application and large demand.
Magnesium is an essential medium nutrient for plants. Magnesium is a constituent element of chlorophyll, and many enzymes activator participate in protein synthesis. The symptoms of magnesium deficiency in crops first appeared on the lower old leaves, with chlorosis between veins, dark green spots on the base of leaves, yellow or white leaves from light green, and brown or purple-red spots or stripes. Grass, soybean, peanut, vegetable, rice, wheat, rye, potato, grape, tobacco, sugarcane, sugar beet, citrus and other crops have a better response to magnesium fertilizer.
Magnesium fertilizer can be used as base fertilizer or topdressing fertilizer. Generally, 13-15 kg of magnesium sulfate is applied per mu. 1-2% magnesium sulfate solution was the best for topdressing (foliar spraying) at the early stage of crop growth. Sulphur is an essential medium nutrient for plants. Sulphur is a component of amino acids. Many enzymes are involved in the redox process of crops. Sulphur is a component of many substances.
