Winter storage of farmyard manure to improve fertilizer efficiency

Cao Lijun, from the Agricultural Bureau of Lujiang City, Hunan Province, said that winter is a season with relatively little fertilizer. In some rural areas, manure is used to pile up manure on the edge of the village, allowing it to wind, rain, sun and volatilize, which not only reduces fertilizer efficiency, but also pollution. The environment, after being applied to the field, is also likely to cause pests and diseases. He suggested that human excrement can be mixed with soil, generally 4 to 5 times the soil is added, and the manure and urine stored in the pool should be added with charcoal (peat), fine dry soil, straw and other nitrogen retention agents. The loss of nitrogen can also be deodorant. After the pig manure is discharged, it must be sealed with mud to prevent nitrogen loss. In the winter, the farmer's fertilizer is stored. If the manure is covered with plastic film and the temperature of the manure is high, some pest eggs and germs will be killed, which can effectively inhibit the occurrence of pests and diseases.
