Farmyard manure has the characteristics of high fertilizer efficiency, long fertilizer period and full fat. However, many farmers have neglected the protection of fertilizer efficiency during storage and storage, resulting in serious losses. Therefore, it is necessary to master the knowledge of fertilizer conservation of some farmyard manure.
First, the plant ash should be a single product. The plant ash contains 6% potassium and 2% phosphorus, which can maintain fertilizer efficiency in the soil for 3 years. Grass ash is a good potash. Potassium fertilizer in the soil can promote the early maturity of crops and enhance the ability to resist lodging and pests and diseases. Many farmers do not understand the knowledge of fat-preserving, put the vegetation and ash, and even pour into the toilet and mix with human waste. According to the research of the scientific research department, after mixing for 3 days, the ammonium nitrogen loss was 34.5%; after 15 days of mixing, the loss was 56.5%; after 90 days of mixing, the loss was 87.5%. Therefore, the storage of wood ash, must have a gray warehouse, stored separately, and to prevent moisture.
Second, the toilet should be covered. Many farmers' toilets just dig a pit. Without cover, the wind and sun exposure of nitrogen fertilizer is much and unsanitary. Therefore, in addition to bricks, stone building cement or replacing with large tanks, farmyard toilets should be covered to ensure fertilizer efficiency, and at the same time, it can also play a safe and sanitary role.
Third, the soil padding livestock circle. According to the test, the livestock in the livestock circle did not lose 81% of the nitrogen loss. Therefore, the livestock circle must use 3 to 4 times more soil potential than the manure. It is mated every 10 to 15 days in spring and autumn, once in summer for 5 to 7 days, and once in winter in January.
Fourth, the mixture of manure and soil. In order to reduce the effort, many farmers have shoveled soil in the fields. Then lay a layer of human and animal waste on the mound, so that the wind, rain, sun, fertilizer loss is serious. It should be changed to a layer of soil, a layer of grass, a layer of human and animal excrement, stacked in layers, and finally sealed with mud in the outer layer of the manure pile to ensure fertilizer efficiency.
5. Cover the soil after the dung. Many farmers use the manure from the pit and pile it in the open air without covering the soil. This will also cause a lot of loss of fertilizer efficiency. Therefore, people and livestock manure from the pit should be covered with soil in time to prevent loss of fertilizer efficiency.
Sixth, film and fertilizer effect. Under normal circumstances, livestock and poultry manure is not easy to ferment. It should be piled up into small piles after being taken out, and poured on warm water of 40 °C, covered with plastic film, which can promote fermentation and protect fertilizer.
