According to crop varieties, for the field crops, NPK ternary compound fertilizer should generally be used. It is not appropriate to apply compound fertilizer with high chloride ion content which is produced by using potassium chloride or ammonium chloride as raw materials. According to the fertilization method, in order to improve the fertilizer efficiency of the compound fertilizer, different compound fertilizers should be selected for different fertilization methods. For example, when making base fertilizer, it is necessary to purchase granular compound fertilizer, or to purchase compound fertilizer containing slow-release fertilizer, which has long fertilizer effect and is beneficial to increase the utilization rate of nitrogen. According to the principle of fertilization, according to the reasonable formula of soil testing results, the balanced supply of nutrients in crops can be realized. It should be noted that the nutrient of the compound fertilizer is relatively fixed, and must not be blindly selected and applied, nor can it be applied as a single fertilizer to avoid unnecessary loss and waste.
