Sheep manure is a very good fertilizer, but it cannot be used directly. How should it be decomposed?

Sheep manure is a kind of high-quality organic fertilizer with high nitrogen content and low water content, and it is one of the common sources of commercial fertilizer in rural areas. Sheep are herbivores, with fine feces, continuous high-temperature chemical fiber lysis, rapid alcohol production, and high alcohol calorie when deposited, which belongs to sexual thermal fertilizer. Sheep dung cannot be used immediately because it contains a lot of grass seeds, germs, larvae and so on. When raising sheep, the principle of sealing ring is to pad thin soil frequently, wet one piece and clean up dung frequently, and dung will pile up, as shown in the following figure.

Sheep manure will not burn seedlings after composting. Because sheep manure is directly applied to the ground without composting, it will cause microbial fever, which will immediately damage crops and plants and kill crop seedlings. After sheep manure is fermented by alcohol, green plants will make better use of the nutrients in sheep manure. After sheep manure is fertilized, most weed seeds will be killed. Applying it to the field can reduce the germination rate of weeds and reduce the work pressure of weeding. Sheep manure, like every organic fertilizer, can only be used after composting.

Sheep manure is rich in pathogenic bacteria and pests such as salmonella and ciliates. If it is applied to the field immediately without composting, it will cause the spread of diseases, but in Shoji, it will cause a lot of heat, leading to the burning of roots and seedlings of crops. Stack the collected sheep manure, and the relative height of the pile shall not exceed one meter. When the tap water is wet, it needs a certain environmental humidity to produce alcohol. The fermentation process is aerobic exercise, and em bacteria or microbial fertilizer can be added. Conducive to stronger alcohol production.

Then use the old agricultural plastic film to block it up and gradually make alcohol. Pay attention to turning over the pile after alcohol is produced. Generally, after 7 days, it is necessary to turn over the pile for comprehensive mixing, and then send alcohol for 7 days. Usually turn over the pile at least twice. The fermentation time is about 20~25 days. Pure sheep manure can be smeared on the road immediately before farming, and then ploughed and raked into the field to realize the integration of grass and mustard. This advantage is that the utilization rate of fertility is high and the damage of base fertilizer is small.
