Fermentation of Animal Manure to Produce Organic Fertilizer

Fermented chicken manure, duck manure, goose dung, pig manure, cow dung, sheep dung, pigeon dung, rabbit dung and other animal manure to make organic fertilizer. For example, adding 10-20% of plant straw is more effective. Common animal manure can be fermented to produce organic fertilizer. After a bag of biological fertilizer starter is formulated into a stock solution (10 kg), two tons of organic fertilizer can be fermented.

The following is an example of making two tons of pig manure organic fertilizer. The operation method is as follows:

Required materials: two tons of pig manure, 200 kg of straw, biological fertilizer starter liquid 10 kg.

The first step: the straw is crushed and cut, preferably 2-3 cm.

The second step: 10 kg of  biological fertilizer starter solution, added to 500 kg of water to dilute (how much water is added according to the dry and wet degree of pig manure).

The third step: mixing the straw with the diluted  biological fertilizer starter liquid and pig manure and stirring evenly.

The fourth step: the mixed pig manure humidity is 65%, the judging method is: hand kneading into a group without dripping water, loosening is appropriate.

Step 5: Stack the mixed pig manure and cover it with straw mat. Note that the organic fertilizer fermentation process is aerobic fermentation and cannot be completely sealed. When the amount is large, it is not necessary to cover it. Just spread 2-5 cm above. Thick straw can be used.

Step 6: Turning the cockroaches, the general fermentation needs to be turned over once in the third and fourth days. If you find that there is no fermented pig manure, you can continue to sprinkle the  biological fertilizer starter solution to help the fermentation; the same operation until fermentation Complete, generally fermented organic fertilizer for 10-15 days.

Pig manure contains not only a large amount of organic matter, NPK and other trace elements necessary for plants, but also various biological enzymes and microbial enzymes. It is a good raw material for organic fertilizer. However, directly applying the decomposed pig manure to the ground will cause the roots of the plants to burn, and a large number of germs will be directly brought into the soil, causing the spread of pests and diseases and animal diseases. In addition, wet manure is extremely inconvenient to transport. Fresh pig manure must be completely decomposed by aerobic fermentation before it can be safely used in the soil.
