What are the common varieties of medium-quantity elements? Currently, the medium-sized element fertilizers that are commonly referred to are silicon, calcium, magnesium, and sulfur fertilizers. These elements are stored in soil in large amounts and can be supplemented when large amounts of elemental fertilizer (nitrogen, phosphorus, and potassium fertilizers) are applied. It can meet the needs of crops. However, with the development of agricultural production, the phenomenon of high concentration of nitrogen, phosphorus and potassium without the lack of intermediate elements has gradually increased. The application of medium-element element fertilizers differs depending on the crop type, soil conditions, and environment. The common varieties of silicon fertilizer are silicon-silicon fertilizer, silicon-manganese fertilizer, silicon-magnesium-potassium fertilizer, sodium silicate, etc.; common types of calcium fertilizer include lime, gypsum, calcium phosphate, calcium superphosphate, calcium magnesium phosphate, etc.; magnesium fertilizer The varieties are calcium magnesium phosphate fertilizer, magnesium sulfate, magnesium chloride, dolomite powder, etc. The main varieties of sulfur fertilizer are calcium phosphate, ammonium sulfate, magnesium sulfate and potassium sulfate. Therefore, some chemical fertilizers contain a variety of elements needed for crops, called multi-element fertilizers. Applying a fertilizer can meet the needs of various elements of crops to some extent. Source:Nongbo.com
