Fermentation process of cow dung fertilizer production line
The fertilizer production machine uses cow dung to process organic fertilizer. The cow dung must be aired or drained to keep its moisture content below 85%. Then, straw powder is added. The ratio of cow dung to straw powder is 7:3 to make raw materials and auxiliary materials. The carbon ratio is controlled at 23%-28%, and the water content is controlled at 52%-68%
