Before using a fermentation compost turning machine to dispose of cattle manure, we need to treat the manure first.
First, we dry or dry the recycled cow dung to control its moisture below 85%, and then mix it with straw, sawdust, mushroom residue, etc., in appropriate proportions (manure accounted for 80-90%, others accounted for 10-20%). Add 1 ton of material (about 2.5 tons of fresh material) with 1 kg of organic fertilizer starter, dilute 1 kg of organic fertilizer starter with 5 kg of rice bran (or bran, corn flour and other substitutes), and then evenly sprinkle into the material pile. When the fermentation compost turning machine is used to turn the raw materials, the temperature is controlled at 55-65℃.
The moisture control method of fermented materials: The moisture content of fermented cattle manure and other livestock and poultry manure should be controlled at 40 ~ 65%.

Moisture is suitable or not to judge the method: hand grasp a handful of cow dung, finger seams see watermark but not dripping, landing that scattered is appropriate. Less water fermentation is slow, more water ventilation is poor, therefore, we must grasp the moisture content. If the moisture is too high, straw, sawdust, mushroom residue, dry soil powder can be added.
In the whole process of fermented compost, we need to use the fermentation compost turning machine to frequently turn them, so that it is ventilated. The fermentation of cow manure to produce organic fertilizer requires oxygen consumption fermentation, so it is appropriate to increase oxygen supply measures in the operation process, so as to mix well, turn frequently and ventilate. Otherwise, it will lead to anaerobic fermentation and produce odor, affecting the fertilizer effect.
