Microbes can be used to decrease the use of chemical fertilizers and pesticides.Explain how this can be accomplished.

Explanation

The use of chemical fertilizers and pesticides can be reduced by the use of biofertilizers and biological pest control methods. Biofertilizers are organisms that enrich the nutrient quality of the soil. The main sources of biofertilizers are bacteria, fungi and cyanobacteria. Many bacteria and cyanobacteria fix the atomospheric nitrogen into organic forms, thus enriching the nitrogen content of the soil. In paddy fields, cyanobacteria serve as an important biofertilizer. Similarly, some microbes (fungi, bacteria and viruses) can be used to control a number of crop pests.
