Describe fertilizers and compare them with biofertilizers and composts.

Fertilizers is any material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants.

First, the presence or absence of microorganisms. Bio-organic fertilizer contains a variety of beneficial microorganisms inside, but all microorganisms in organic fertilizer after high temperature treatment substantially are killed, which is difficult to provide beneficial soil microbes.

Second, different nutrients. Organic fertilizer through high-temperature treatment, nutrient losses during treatment of high temperature.

Third, different odors. Organic fertilizer by drying, deodorizing effect of organic fertilizer is not ideal because of drying treatment. once organic fertilizer is damp, stench is issued. Bio-organic fertilizer fundamentally eliminate the odor, because it can turn uric acid into the urine bacterial protein.
