The traditional way of treating livestock and poultry manure is often to pile it up randomly or simply return it to the field, which not only easily breeds bacteria and pollutes the environment, but also causes nutrient loss and soil compaction. With the increasing emphasis on green agriculture, the market demand for organic fertilizers from livestock and poultry manure is growing day by day. However, traditional processing methods have low efficiency and unstable product quality, making it difficult to meet market demand. Therefore, it is urgent to choose efficient and intelligent processing equipment and build a modern livestock and poultry manure organic fertilizer production line.
