Product characteristics of compound fertilizers

The production of compound fertilizers often uses soil testing formulas to measure the nutrient status of the soil. Soil testing formula fertilization is based on soil testing and fertilizer field experiments, and proposes the application quantity, fertilization period, and application method of nitrogen, phosphorus, potassium, and medium and trace elements based on the crop fertilizer demand law, soil fertilizer supply performance, and fertilizer effect, on the basis of reasonable application of organic fertilizers. Simply put, it means applying formula fertilizer scientifically under the guidance of agricultural technology personnel. 

The core of soil testing formula fertilization technology is to regulate and solve the contradiction between crop fertilizer demand and soil fertilizer supply. At the same time, targeted supplementation of nutrients required by crops, supplementing whatever elements are lacking and as much as needed, to achieve a balanced supply of various nutrients and meet the needs of crops; To achieve the goal of improving fertilizer utilization efficiency and reducing dosage, increasing crop yield, improving agricultural product quality, saving labor, and increasing income.
