The simplest and practical treatment method of pig manure

The simplest and practical treatment methods of pig manure include making chemical fertilizer, composting, making biogas, cultivating aquatic plants, and cultivating fish and shrimp.

1, making fertilizer

Making pig manure into chemical fertilizer is the most commonly used treatment method in our traditional agriculture, which can not only solve pig manure, but also increase soil fertility. Generally, pig manure is soaked in water, fermented and mixed with soil, weeds, dead leaves and fallen leaves. And then pour it into the ground, which can improve the fertility of the soil.

2. Compost is decomposed

Make pig manure into fertilizer, but use soil instead of water. After the pig manure is piled up and covered with soil, the internal temperature naturally rises, reaching above 50-70℃. This temperature can kill most germs, and then it can be used to fertilize vegetable fields.

Step 3 make biogas

Biogas is a kind of natural gas energy, which is mainly made of biomass rich in nutrients. Pig manure is rich in nutrition. After pouring into the biogas digester, it is easy to raise the heat to the critical point, and then it will decompose itself, producing a large amount of biogas and generating energy.

Step 4 Cultivate aquatic plants

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

Step 5 Cultivate fish and shrimp

Pig manure is fine in texture and contains more nitrogen, which is easily decomposed by microorganisms, releasing effective nutrients that can be absorbed and utilized by fish and shrimp, and can be used as good feed for fish and shrimp.
