How to treat pig manure?

To deal with pig manure produced by pig rearing, you can use to make fertilizer, compost, make biogas, cultivate aquatic plants and other methods. It is feasible to wash pig manure with water, ferment it, pile it in the soil to ferment and produce heat, pour it into the digester to decompose and ferment it to produce biogas, and cultivate water hyacinth to decompose pig manure.

How to deal with pig manure produced by raising pigs

1, make fertilizer

Making pig manure into fertilizer is one of the most common treatment methods in our traditional agriculture, which can solve the problem of pig manure, but also increase soil fertility. Soak hog manure in water, ferment it, and mix it with soil, weeds, dead and fallen leaves. Watering it in the ground will increase soil fertility.

2, compost rot

Another method is also to make pig manure into fertilizer, but instead of using water, use soil. When pig manure is piled up and covered with soil, the internal temperature naturally rises above 50-70 degrees Celsius. This temperature kills most germs and can then be used to fertilize vegetable plots.

3, making biogas

Biogas is a natural gas energy source, mainly made from nutrient-rich biomass, and pig manure is rich in nutrients. After pouring into the digester, it is easy to raise the heat to the critical point, and then it will decompose by itself to produce a large amount of biogas, reduce the secondary infection and produce energy.

4, breeding aquatic plants

Similarly, nutrient-rich pig manure can be used to cultivate fertilizer-tolerant aquatic plants. We can prepare or dig a pond in which we can grow some aquatic plants such as water hyacinth and manchurian. These fertilizer-tolerant plants can decompose and purify pig manure in a week or so.
