This product is widely used in all kinds of fruits and vegetables, cash crops and field crops, suitable for all kinds of soil, save labor and dissolve quickly, easy to absorb, quick effect, high utilization rate, can be sprinkler irrigation, flushing, spreading and so on.

According to the different growth periods of crops and soil conditions, and combined with the local fertilization situation, the method and amount of fertilizer should be properly mastered.

In the production of compound fertilizer, soil testing formula is used to measure the nutrient situation of the soil. Soil testing formula fertilization is based on soil testing and fertilizer field experiments. According to the law of crop fertilizer demand, soil fertilizer supply performance and fertilizer effect, on the basis of reasonable application of organic fertilizer, the application amount, fertilization period and application method of nitrogen, phosphorus, potassium and medium and trace elements are proposed. Generally speaking, it is the scientific application of formula fertilizer under the guidance of agricultural science and technology personnel. The core of soil testing and formula fertilization technology is to adjust and solve the contradiction between crop fertilizer and soil fertilizer. At the same time, we should supplement the nutrient elements needed by crops in a targeted way. We should supplement whatever elements the crops lack and supplement as much as needed, so as to realize the balanced supply of various nutrients and meet the needs of crops. To improve the utilization rate of fertilizer and reduce the amount of fertilizer, increase crop yield, improve the quality of agricultural products, save labor, save expenditure and increase income.
