Therefore, it is very important to correctly grasp the precautions of fertilizer use.
Fertilizer type and selection
1. Organic fertilizer: including farm manure, green manure, rich in organic matter and trace elements, can improve soil fertility. However, attention should be paid to the degree of maturity to avoid root burning caused by the application of raw fertilizer.
2. inorganic fertilizer: nitrogen, phosphorus, potassium and other nutrients, such as urea, diammonium phosphate, etc. The application should be reasonably matched according to the needs of crops to avoid nutritional imbalance caused by single application.
3. Compound fertilizer: contains a variety of nutrients, easy to apply. However, attention should be paid to the proportion of nutrients to avoid waste or soil pollution caused by excessive application of a certain element.
