Abstract:

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. The soil texture varied from sandy to clayey. The soils varied widely in OC (0.39-1.20 percent), bulk density (0.97-1.67 gm/cc), pH (4.5-5.4), base saturation (18.1-50.9 percent) and available N (501.8-715.0 kg ha-1), P2O5 (9.8-32.1 kg ha-1), K2O (241.9-392.3 kg ha-1). The bacterial and fungal population ranged from 44-236 cfu x 106 and 2.90-25.55 cfu x 102 per gram soil, respectively. The SMBC was observed to be the highest under forest vegetation and was the lowest in agricultural cropland. In the present study, wide variations were observed in SMBC which were related to seasonal variation and varied land uses.
