First, the fermentation in the soil will produce heat to affect the root growth of the crop; second, it contains a large number of germs and eggs, and the crop is vulnerable to pests and diseases; third, the nitrogen fertilizer in the unfertilized manure is mainly uric acid or urate. Crops can not only absorb, but also harmful crop roots.
