Soil is a living biological system in which millions of microorganisms play a silent but dynamic role that leads to agricultural productivity. Prior to the 1940s, research into these soil microbes was limited to specific groups and genera, and was considered important from the agricultural point of view because it directly contributed to soil fertility. The most important members of the soil bacteria were Azotobacter. Thiaoblum and autotrophic nitrifiers, while phytopathogens such as Agrobacterium. In India, soil microbiology is a neglected science. Our knowledge of these microorganisms is based primarily on working in other countries, because we view our country as very large and the climatic and agronomic conditions are in contrast to other countries. There is still much work to be done to understand the microbiology of soil types from India.
