What should we pay attention to when applying organic fertilizer?

Need to avoid mixed use of organic fertilizer? What kind of organic fertilizer is suitable for base fertilizer? Which organic fertilizers are suitable for topdressing? The following land network is briefly introduced for netizens' reference. The nutrient content and properties of different organic fertilizers are very different, so the following matters must be paid attention to when applying. 1. In addition to the crop straw directly returned to the field, organic fertilizer generally needs to be treated by composting to make it fully mature before it can be applied to the soil, especially high-calorie organic fertilizers such as cake fertilizer and chicken manure should pay special attention to this to prevent burning seedlings. 2. Human feces and urine is an available organic fertilizer with high nitrogen content, which is suitable for topdressing. It is necessary to go through harmless treatment before application, and it depends on crop application, such as excessive application on taboo crops, which will lead to a decline in quality. Long-term single application of human feces and urine in the soil must be combined with a certain amount of manure, compost, retting fertilizer and other organic matter-rich fertilizers to ensure a balanced supply of soil nutrients. 3. Compost, retting manure and biogas residue compost contain a lot of humus, which is suitable to fertilize the soil. However, because there are a lot of organic matter that has not yet completely decomposed, these fertilizers should be used as base fertilizer, not as topdressing fertilizer. 4. Plant ash contains 5% to 10% potassium oxide, which is alkaline and cannot be mixed with rotten human feces, urine and stable manure, so as not to reduce fertilizer efficiency.
