Before planting vegetables, you must choose suitable fertilizers, generally slow-acting fertilizers, such as organic fertilizer, farmyard manure, cake fertilizer and so on. Be careful not to use immature farmyard manure, otherwise it will easily breed pests and diseases and burn plants.
2. Deeply cultivate and use it freely.
Before applying base fertilizer, we need to deeply turn the vegetable field to make it loose and breathable, and then spread the fertilizer evenly into the soil. When applying slow-release fertilizer, it is best to apply it in the upper, middle and lower layers of soil respectively, so that the nutrients in the soil can be more comprehensive and sufficient.
3. Concentrate fertilization.
If you want to apply some compound fertilizer, in order to avoid the volatilization of fertilizer nutrients, you can dig a ditch after deeply ploughing the soil, then sprinkle the base fertilizer into the ditch, and finally cover it with a thin layer of soil to avoid the contact between the fertilizer and the air and the loss of nutrients.
