How to choose a suitable compound fertilizer?

How to choose a suitable compound fertilizer? Please introduce the method to choose the appropriate compound fertilizer can refer to the following methods: first, select the compound fertilizer suitable for the soil. When choosing compound fertilizer, we must have some understanding of the soil conditions, and choose the fertilizer with suitable nutrient content and nutrient distribution ratio according to the soil fertility. Secondly, choose the compound fertilizer suitable for crop growth. Potassium plays a special role in improving the quality of crops. In the case of little use of potassium fertilizer, potassium-containing compound fertilizer should be given priority to cash crops. Thirdly, suitable compound fertilizer is selected for different soils and different crops. Nitrophosphate fertilizer system is suitable for acid soil and upland soil, chlorophosphate iridium system is suitable for neutral and calcareous soil, and urea phosphorus hinge system is suitable for all kinds of soil and crops. It is not suitable to use compound fertilizer containing potassium sulfate for crops containing chlorine, while compound fertilizer containing potassium chloride can be used for grain crops. Finally, it was applied in combination with unit fertilizer. Because the nutrients of compound fertilizer are relatively fixed, properly combined with unit fertilizer, the ratio of nitrogen, phosphorus and potassium can be adjusted to meet the requirements of different soils and different crops.
