Compost is a mixture of various organic substances and can be used as fertilizer. Although organic matter is any once living substance, the materials used for composting come from the vegetable garden/garden and kitchen (kitchen waste) when parking.
Compost is produced by the final decomposition and decay of various components. Compost may take 2- 18 months from production to use. The length of time depends on the method, composition, season and frequency of composting.

Precautions:
1, the fertilizer pile should be large but not small: the climate is cold in severe cold season. In order to promote the decomposition of fertilizer piles, the amount of fertilizer piles accumulated in winter should be increased appropriately. Generally, it is better to have a diameter of 3 ~ 4 meters and a height of about 2 meters. Rectangular compost piles with a height of 2m, a width of 1.50 ~ 2m and a length of 4m can also be used.
2. The fertilizer pile is too low and narrow, cold air invades, heat dissipates quickly, fertilizer decomposes slowly, and the quality is poor. In addition, some farmers transport small piles of fertilizer to farmland or scatter them on the ground in winter and spring. These practices are very unfavorable to nitrogen conservation.
3. In winter, in addition to storing fertilizers in large piles, soil covering measures should be taken to seal mud around the fertilizer piles and at the top of the piles, that is, covering 1 layer of soil or 1 layer of wheat straw mud to prevent cold air from entering the piles and hot air from being emitted. At the same time, cover the soil and seal the mud, block the channel of nitrogen volatilization loss and reduce nitrogen loss.
