At present, the application rate of chemical fertilizers is increasing year by year, while many farmers have neglected the accumulation and application of farmyard manure, resulting in a serious loss of nutrients in a large number of farmyards. According to estimates, if the livestock urine is not in time, the nitrogen loss can be as high as 96% after half a month. Therefore, to prevent the loss of nutrients in farmyard fertilizers, it should be highly valued by farmers' friends.
First, reduce the loss of livestock manure and urine nutrients. Improve the rims, so that it does not leak water, does not leak the fertilizer, and it is easy to use the gasket; the floor of the sill is properly padded, and the ratio of excrement to soil is 1:3-4, so that you can work hard, daily or every other day. Once the circle is taken out; if it is not used temporarily, it should be piled up immediately, and the outer part should be sealed with mud to ensure fertilizer efficiency.
Second, reduce the loss of manure and urine nutrients. Human urine is rich in nitrogen, phosphorus and potassium. According to the measurement, if the human urine is not treated, it will be stored in the tank for 60 days, and the nitrogen loss will be about 90%. The method of reducing the loss of human urine nutrients is: the urine is stored in the tank or the pool, and it must be covered in the tank or the pool to prevent evaporation. It is best to use it for 7-10 days to reduce the accumulation time to save nutrients.
The method for reducing the loss of manure nutrient is: (1) Fix the toilet and the septic tank to prevent seepage, leakage, rain, and cover. (2) Change the method of use, that is, to dry the application as a dilute application, and to dilute the matured manure into the soil. Its maturity time is generally 6-7 days in summer and 15-20 days in other seasons. (3) Human feces and urine should be strongly promoted.
Third, reduce the loss of nutrients in the plant ash. Because the plant ash contains a large amount of potassium carbonate, it is the only alkaline potassium fertilizer in the farmyard manure. The human excrement and the manure are all acidic organic fertilizers, so the two will be mixed and the nutrients will be lost a lot. It was determined that the plant ash was mixed with human excrement in a ratio of 1:1.5 and stored for ten days. The nitrogen loss was about 27.4%, and the nitrogen loss during storage for three months was about 85.9%. Therefore, we should vigorously promote the monoculture, single storage, and single use of grass ash, and avoid dumping the ash into the organic fertilizer, and at the same time prevent the ash from being wet by the rain, resulting in nutrient loss.
