How to treat pig manure into organic fertilizer

The methods of treating pig manure into organic fertilizer include mixing, stacking, moisture requirement, temperature requirement and turning over and ventilation.

1. Material ratio: pig manure 1.5 tons, fertilizer starter 1 kg. The starter should be evenly mixed with rice bran according to the ratio of 1: 5, then evenly sprinkled into the pig manure pile and stirred evenly.

2. Material stacking: stacking should not be too small or too short. Too small will affect fermentation.

3. Moisture requirement: The moisture content of fermented materials should be controlled at about 65%.

4. Temperature requirements: the initial temperature should be above 65438 05℃, and the fermentation should be carried out indoors or in the greenhouse in winter.

5. Stacking ventilation: Pay attention to proper oxygen supply during fermentation, and turn over the stack once every two days on average.

6. Fermentation is completed: generally, fermentation can be completed within one week, and the substance is dark brown. When the temperature begins to drop to normal temperature, it indicates that the fermentation is complete.
