Raw material particle size: The particle size of sheep manure and auxiliary raw materials should be below 10mm, otherwise it should be crushed. Suitable material moisture: The optimal humidity of composting microorganisms is 50~60%, the limit humidity is 60~65%, and the material moisture is adjusted to about 55~60%. When the water reaches more than 65%, it is impossible to ferment the dead tank.

Control of sheep manure and auxiliary materials: According to local agricultural conditions, organic materials such as straw, corn straw, and peanut straw can be used as auxiliary materials. According to the requirements of fermentation water, the ratio of chicken manure to auxiliary materials can be adjusted. Generally speaking, it is 3:1, and the compost material can choose 20~ 80:1. Therefore, organic matter such as dry straw, corn straw, leaves, soybean stems, peanut stalks, etc. commonly found in rural areas can be used as auxiliary raw materials for compost fermentation.

Fermentation period: Mix sheep manure, auxiliary materials and inoculation materials into the tank, turn it over for the first time, and record the start time of the fermentation cycle. Generally, the heating period in winter is 5 to 7 days after 3 to 4 days, and enters the high-temperature fermentation stage. According to the temperature, when the temperature of the pile exceeds 60-70 degrees and is maintained for 24 hours, double piles can be used, and the number of piles varies with the seasons. The fermentation cycle in summer is generally 15 days, and the fermentation cycle in winter is 25 days.

If the tank body is found to be no more than 40 degrees after 10 days, the tank can be judged as dead and the fermentation startup fails. At this time, the water in the water tank should be measured. When the water content is greater than 60%, supplementary materials and inoculation materials should be added. If the water content is less than 60%, consider whether the inoculation amount is insufficient.
