Fermentation of pig manure organic fertilizer technology

1. Directly transport the pig manure to the biogas digester for fermentation, after the fermentation is completed, the biogas liquid and residue is high-quality organic fertilizer;

2. Combine the pig manure with 20-40% of the crushed straw (sun-dried), so that the moisture content is in a suitable range, and then the fermentation bacterium is fully mixed with it and closed for 7-15 days to check whether it is completely fermented, and if it has been completely fermented, then you can directly apply it or pelletize it and package it. If it has been fully fermented, it can be applied directly or packaged after granulation. If the fermentation is not complete, then you need to continue to closed fermentation, high temperature is conducive to accelerate the fermentation.

3. Pitch the pig manure into the fermenter, add appropriate amount of water, then add the fermentation bacteria or natural fermentation, and then apply liquid fertilizer after the fermentation is completed.
