Seasonal variations in microbial biomass carbon and its relationship with some soil parameters were studied in Ri-Bhoi District of Meghalaya. Soil samples were drawn from the soil horizons of three land uses (Table A) in pre-monsoon, monsoon and post-monsoon seasons. The SMBC in all the land uses decreased significantly with depth however SMBC is found to be different from one land use to another. SMBC differs from one season to another and seasonal variation was significant as SMBC attained its peak in monsoon season. In case of soil physico-chemical parameters, organic carbon, available N, P, K showed significant depth-variation. | Seasonal dynamics of soil microbial biomass carbon (SMBC) in different land uses in Ri-Bhoi district of Meghalaya, India
