How can fertilizer be applied for the best effect? Master scientific fertilization methods
Many fertilizers are used in crop cultivation, and each has its own characteristics. For example, organic fertilizers and inorganic fertilizers, solid fertilizers and liquid fertilizers, macronutrients and micronutrients, single fertilizers and compound fertilizers, etc. Different fertilizers should be applied using different fertilization techniques. Generally, slow-release fertilizers such as organic fertilizers and compound fertilizers should be used as base fertilizer,...
Many fertilizers are used in crop cultivation, and each has its own characteristics. For example, organic fertilizers and inorganic fertilizers, solid fertilizers and liquid fertilizers, macronutrients and micronutrients, single fertilizers and compound fertilizers, etc. Different fertilizers should be applied using different fertilization techniques. Generally, slow-release fertilizers such as organic fertilizers and compound fertilizers should be used as base fertilizer, while quick-acting fertilizers should be used as topdressing, and inorganic fertilizers should be applied in combination with organic fertilizers. The application methods should differ for each type. For easily volatile fertilizers such as ammonium sulfate, ammonium nitrate, and ammonium bicarbonate, it is best to apply them deep in the soil. This helps improve fertilizer efficiency, avoids fertilizer coming into contact with seeds and seedlings due to overly shallow application, and prevents seedling burn. For phosphorus and potassium fertilizers such as superphosphate, potassium chloride, and three-element compound fertilizer, surface application has little effect, so they should be evenly mixed into the soil layer. For water-soluble chemical fertilizers such as urea and high-nitrogen compound fertilizers, topdressing works well. In addition, fertilizers such as phosphorus, potassium, boron, zinc, manganese, and molybdenum can also be used for foliar topdressing.
