First of all, commercial organic fertilizer is "harmless" than manure: First, organic fertilizer contains more salt, which is easy to make the soil salinized. The second is that the feces contain a large number of germs and insect eggs, which are most likely to cause greenhouse diseases and insect pests. The third is that the nutrient content of manure is unstable and cannot be supplemented reasonably. Fourth, if the feces contain harmful substances and heavy metals, they cannot be removed by high-temperature fermentation alone.
Secondly, the effect of commercial organic fertilizer on soil improvement is faster. If the soil is in poor condition, it is faster to use a commercial organic fertilizer than organic fertilizer.
Finally, the nutrient distribution ratio of commercial organic fertilizers is more reasonable. Various nutrients in commercial organic fertilizers are adjustable, and products with different nutrient contents can be used in different soil conditions.
After the pretreated livestock and poultry manure is fermented in the organic fertilizer stirring and fermentation device, an appropriate amount of nitrogen, phosphorus, potassium and other elements are added in a certain proportion to make the contained trace elements meet the organic fertilizer production standard, and then it is stirred, crushed and formed , granulation, drying, packaging and other processing techniques to process livestock and poultry manure into organic fertilizers with high fertilizer efficiency, convenient transportation, safe use and affordable prices.
