After about 1 week, the temperature of the reactor will rise to about 60-70°C (a relatively long time in winter). After 10 days, the reactor will be piled up once and then added with water.

At this time, the compost can be compacted and tightly sealed with soil to keep the nutrients in reserve. Compost is generally used as a basal fertilizer, applied in combination with the ground and fully mixed with the soil. Compost is suitable for a variety of soils and crops. Generally sandy soils can use semi-mature compost, and viscous soils must use completely decomposed compost. The application of compost can increase soil fertility and supplement a large number of microbial communities in the soil, and it can bring long-lasting and stable nitrogen, phosphorus, potassium and organic-type fertilizers such as calcium, magnesium and sulphur to the crops, which is conducive to the growth of crops.
