1.Ensure that the bottom of the material is ventilated and oxygenated during composting.

2.Composting depth in fermentation tank should be 0.8-1.5m. Too small compost depth is not conducive to temperature rising and ripening; too deep compost depth is easy to cause insufficient ventilation oxygen.

3. If the material is stored too long or the straw contained too much, the fermentation needs to add fresh manure to adjust.

4. The first fermentation is generally 10 days to half a month, and this process is mainly to achieve ripening; materials usually need to be aged and fermented twice after passing through the compost machine, and the time needed is from three days to a week.
