At the 2021 International Agricultural Machinery Exhibition, we interviewed Mr. Qi Yubo, the general manager of Dalian Rainforest Irrigation Equipment Co. The exhibition brought several types of organic fertiliser application and return equipment, of which there are two main sections, one belonging to the solid organic fertiliser throwing operation return vehicle, and the other belonging to the liquid organic fertiliser methane application and return vehicle. How do these amazing equipment manage to convert livestock manure into organic fertiliser?
