Climate change is the most important factor for global agriculture as well as for Indian agriculture. The climate change in the form of increasing the temperature as well as increased rate of the precipitation. The change in the climate over the continent create the change in the agro- ecosystem by changing in the biogeochemical cycling of the natural resource. Because of change in the climatic conditions it will change by altering the forest productivity, plant physiology and the soil physical, chemical and biological processes. Indirectly affect the natural environment of the living organisms. These changes were affected the biodiversity of plant, animal and the soil biological properties, like reducing in the population of the soil bacteria, fungi, and many others. The effect of climate change on the composition and structure of soil microbes and it reducing the number of keystone species and their community structure. The importance of climate change phenomena in agro-ecosystem is well recognised and discussed, about the actual mechanism of change in the soil system and their response to the changing climate is vast and it is still beyond away from the understanding of research scientists. It is already argued that to understand impacts of climate change on the agro-ecosystem and the mechanisms coming under them and requirement of explicit consideration of linkages between the above and below ground biota. The overall effect of climate change mechanism on the function and structure of terrestrial agro-ecosystem is indirectly related to their effects on the soil biota and the processes. Here we are discussing about the impact of climate change on the agro-ecosystem i.e., soil biota and their activities and how these changes are affect nutrient dynamics and their effects on the productivity and structure of agro-ecosystem
