How to compost pig manure in organic fertilizer production lines?

1. Proportion: 1.5 tons of pig manure (about 2.5 tons of fresh manure) need 1 kg of fertilizer starter. And the starter needs to be mixed with rice bran (or bran, corn flour and other substitutes) in a ratio of 1:5. Then sprinkle evenly into the pig manure pile and mix.
2.Temperature requirements: The start up temperature should be above 15℃, and try to ferment indoors or in a greenhouse in winter.
3. Making material pile: When making piles, it cannot be made too small or too short. Too small will affect fermentation. The fermentation effect of piles with a height of 1.5 meters to 2 meters, a width of 2 meters and a length of 2 to 4 meters is better.

4.Aeration: During the fermentation process, pay attention to proper oxygen supply and turn the pile. You should turn over several times by crawler type compost turner when the temperature rises to 75°C or above and control the temperature rise to about 65°C. Too high temperature has an impact on nutrients.
Generally, the fermentation can be completed within a week. The material becomes dark brown, and the temperature begins to drop to room temperature, indicating that the fermentation is complete. If there are too many auxiliary materials such as sawdust, wood chips, and rice husks, the fermentation time should be prolonged until fully decomposed. Welcome to contact us for more details.
