The main components of peanut shell are lignin and cellulose. It contains a small amount of trace elements such as NPK and a small amount of protein. It may be the most productive fertilizer for plants. However, if pure peanut shell is used as organic fertilizer, its nitrogen, phosphorus and potassium content is very low, and the nitrogen content is only 0.65%, so it can be said that the nitrogen content is very low, which leads to the slow fermentation process of pure peanut shell and is not easy to rot; However, these trace elements and protein can't provide enough nutrition for crops, so if only pure peanut shells are used to fertilize farmland, it will not only loosen the soil, but also have an unsatisfactory impact on crops.
Peanut shells are mainly composed of lignin and cellulose. Even after high-temperature fermentation and fermentation, these peanut shells are difficult to completely decompose, which affects the absorption and utilization of nutrients by crops and weakens the water-holding capacity of soil. Crushing peanut shells, destroying peanut shell fibers and decomposing them, reducing the air content between peanut shells, which is beneficial to microbial reproduction, accelerating heat transfer and shortening fermentation time.
In the fermentation process of fermented peanut shells, other livestock manure with high nitrogen content can be added for composting and fermentation decomposition to speed up the fermentation process and make compound organic fertilizer, so that the decomposed organic compound fertilizer can not only improve soil fertility and soil aggregate structure, but also enrich nutrient elements, increase crop yield and enhance disease resistance.
