[0002] The production process of bio-organic fertilizer mainly refers to the production process of organic fertilizer from raw materials to semi-finished products. There are two main production processes used in production, one is the flat windrow composting process, the other is the trough aerobic fermentation process. In the existing market, the flat windrow composting process is more widely used due to its small investment and relatively simple process. The process steps include: raw material processing, adding bacteria, mixing, composting, and turning the compost. Turning the compost is to turn the raw materials in the composting and fermentation process so that it can ferment more evenly.
