Write a short note on agricultural uses of Microorganisms.

  • Microorganisms play a very significant role in agriculture.They can break down organic matter and decompose it completely. It helps in mineralization in which nutrients are returned into the soil in their mineral forms.
  • The components left after complete decomposition are known as humus which remain unchanged in the soil for potentially millennia. This humus helps to retain soil moisture.
  • The microorganisms secrete polysaccharides, gums, and glycoproteins which binds the soil molecules together and improve soil structure. Soil microbes can fix atmospheric nitrogen.
  • For example, the association of Rhizobium bacteria with the root nodules of legumes.
