Although the decomposed cake fertilizer is organic fertilizer, its carbon-nitrogen ratio (C/N) is relatively small, and it is rapidly decomposed into the soil. It is a fast-acting organic fertilizer and can therefore be applied directly. Such as using river water, human urine soaked application. Such as using river water, human urine soaked after application, although the fertilizer effect is fast, but can cause 10% of nitrogen loss, 22.5% of the organic matter loss, disadvantages more than profits. For Fertilizer Some peasants like to use cake fat as a fertilizer and apply it around the seeds, which is more risky. The cake fertilizer is a hot fertilizer that produces high temperatures during the process of fermentation decomposition. If it comes into close contact with the crop, it often causes root burning and affects seed germination and seedling emergence. The correct application method for cake fat is: 1. The cake fat can be mixed with compost and manure and used as base fertilizer, or it can be used as top dressing alone. As top dressing, the cake can be fully crushed and directly applied in open trenches, and attention should be paid to keeping a proper distance from the seedlings of the crop so as to prevent the seedlings from burning heat generated during the fermentation of the cake. According to the experiment, the use of cake fat as top dressing has a smooth and long-lasting fertilizer effect, and the effect is better than that of chemical fertilizer, and there is an aftereffect. 2. When the cake fat is directly applied, because of its own fragrance, it is easy to attract underground pests. Therefore, it should be mixed with appropriate amount of pesticides for prevention. 3, when the amount of cake fat is limited, priority should be given to vegetable and cash crops for top dressing.
