How to apply the cake fertilizer reasonably
1. What problems still exist in the use of cake fertilizer?
Cake fertilizer is a good source of organic fertilizer, and it has many applications in production. According to the author's investigation in rural areas, due to the insufficient understanding of the characteristics of cake fertilizer by farmers, there are still some problems in the use of cake fertilizer, mainly in the following two aspects.
1.1 is applied after decomposing. Although the cake fertilizer is an organic fertilizer, its carbon to nitrogen ratio ((C/N) is small, it is faster to decompose after being applied to the soil, and it is a quick-acting organic fertilizer, so it can be directly applied. If it is soaked with river water, human waste, etc. Application after decomposing, although the fertilizer effect is fast, it will cause about 10% of nitrogen loss and about 20% of organic matter loss.
1.2 is for seed fertilizer application. Some people like to use cake fertilizer as a fertilizer and apply it around the seeds. This is a more risky approach. The cake fertilizer is a hot fertilizer. It produces high temperature during the fermentation decomposition process. If it is in close contact with the crop, it will often cause root burning and affect the seed germination and emergence.
2. What should I pay attention to when using the correct method?
2.1 Cake fertilizer can be used as base fertilizer after mixing with compost and manure, or it can be used as top dressing alone. For top dressing, the cake fertilizer can be fully pulverized and then directly ditched, and attention should be paid to keep the proper distance from the crop seedlings to prevent the heat generated by the cake fertilizer from decomposing and fermenting to burn the seedlings. According to the test, using the cake fertilizer as top dressing, the fertilizer effect is stable and lasting, the effect is better than the fertilizer, and the effect is longer.
2.2 When the cake fertilizer is directly applied, it is easy to attract underground pests because of its own flavor, so it is necessary to mix with appropriate amount of pesticides for prevention.
2. 3 When the amount of cake fertilizer is limited, priority should be given to topdressing on melon crops and cash crops.
