10 Major Roles of Soil Microorganisms for Fertility Enhancement

Soil Microorganisms Roles in Increasing Fertility

    Soil Microbiologist says that soil fertility is directly associated with soil biological health.There are hundreds of millions to billions of microorganisms in a single gram of soil. There are many key roles in fertility enhancement by microorganisms are given below:

1. Soil microbes plays an important role in nutrients cycling like carbon, nitrogen and oxygen etc.
2. Microorganisms decompose the organic matter maintain the soil structure.
3. Microorganisms maintain soil quality and health by improving soil aeration and penetratibility.
4. It is reported fact that microbes can maintain pH for optimum plant growth. Microbes shows maximum growth in acidic soils.
5. Microbes are also responsible for the decomposition of organic matter as well as pesticide residues. 
6. Soil microbes not only contribute the better crop as well as improve the soil ecosystem.
7. Fungi make symbiotic relationship with the legume crops for nitrogen fixation and improve soil health.
8. Promote plant growth by provision of  growth hormones and growth regulators.
9. It is reported that almost 60% nitrogen is fixed by microbes.
10. Some microbes are used for the control of soil borne and seed borne disease.
