Terrestrial ecosystems consist of above- and below-ground components that interact to influence community- and ecosystem-level processes and properties. Soils act as the most important medium for linking the above and below ground community which are of very sensitive to any external disturbances. To study the effect of disturbances and also the influence of crop to soil microbial community which are an indicators of biological soil processes a short cycle of jhum practices from Mizoram was selected and study in a microcosm experiment. The experiment was carried out in four (4) set where there was burnt soil which consist of rice crop and without rice crop and unburnt soil where there was rice crop and without rice crop. The study reveals that the soil bacterial community composition altered significantly due to burning of slashed biomass on soil surface. The introduction of rice crop also altered the bacterial community composition in burnt/unburnt which shows a distinct cluster within the soil type. The Alpha proteobacterial communities of burnt and unburnt without rice crop clustered together and distinctly separated from the clusters of burnt and unburnt soil with rice crop at 45 days of rice growth and at 90 days of rice growth the impact of rice crop.
