The difference between decomposed and unfertilized fertilizer: fermentation

After the fermented fertilizer is fermented before use, the microorganism decomposes the organic animal and plant residues and feces into components that the plant can absorb; the unfermented fertilizer is not fermented before use, and if it is directly applied, the fermentation is completed in the soil.

The difference between decomposed and unfertilized fertilizer: oxygen

The decomposed fertilizer requires a large amount of oxygen during the fermentation, which will generate a large amount of heat and toxic gas, but will not compete with the plant for oxygen when applied; while the unfertilized fertilizer will be fermented in the soil when applied, and will compete with the plant for oxygen, the heat generated. Will burn the roots.

The difference between decomposed and unfertilized fertilizers: impurity

The composted fertilizer has less impurities, and the unfermented fertilizer contains a large number of germs and eggs, and the plants are vulnerable to pests and diseases.

Distinguish between decomposed and unfertilized fertilizers: gas

蚯蚓 can survive in the soil where the fertilized fertilizer is applied, which can loosen the soil and promote the development of the roots of the plants; while the unfertilized fertilizer has residual phenol or ammonia, which is not suitable for survival.

Distinguish between decomposed and unfertilized fertilizers: utilization

Some of the nutrients of the decomposed fertilizer are converted into quick-acting nutrients, which can be quickly absorbed by the plants; while the nitrogen fertilizer in the unfertilized fertilizers exists in the form of uric acid or urate, the crops are not only absorbed, but also harmful to the root growth of the crops.
