The following points should be paid attention to during the process of sheep manure fermentation

Particle size of raw material: the particle size of sheep manure and auxiliary raw material should be less than 10mm, otherwise it should be crushed. Suitable material moisture: the optimum humidity of composting microorganism is 50~60%, the limit humidity is 60~65%, the material moisture is adjusted to 55~60%. When the water reaches more than 65%, the “dead pot” is impossible to ferment.

 Sheep manure and material control: according to the local agricultural situation, straw, corn stalks, peanut straw and other organic material can be used as auxiliary materials. According to the water requirement during the fermentation process, you can adjust the proportion of dung and accessories. Generally speaking, it is 3:1, and composting material can choose from 20 to 80:1 carbon nitrogen ratio between material. Therefore, the rural common dry straw, corn stalks, leaves, soybean stalk, peanut stalk, etc. all can be used as the auxiliary materials in the process of composting fermentation.

 Fermentation period: mix sheep manure, accessories and vaccination materials and place in the fermentation tank, mark the start time of fermentation period, generally the winter heating period is 3 ~ 4 days, and then the coming 5 ~ 7 days, is the high temperature fermentation stages. According to the temperature, when the temperature of the pile body is more than 60-70 degrees and keep 24 hours, it can double pile, pile number changes with the change of seasons. Summer fermentation period is 15 days commonly, winter fermentation period is 25 days.

If the fermenter temperature is not more than 40 degrees after 10 days, the tank can be judged dead and the fermentation startup fails. At this time, the water in the tank should be measured.When the moisture content is more than 60%, supplementary materials and inoculation materials should be added. If the moisture content is less than 60%, the inoculation quantity should be considered.
