Abstract/Description: | A field experiment was conducted in clay loam of Wetlands of TNAU farm, Coimbatore to study the impact of nutrient management technologies on Soil Microbial Biomass-Carbon (SMB-C) and Dehydrogenase Activity (DHA) of soil under lowland rice ecosystem. In the present investigation, integration of inorganics, Sesbania aculeata and biofertilizers have intensively triggered the microbial activities, which would have resulted in higher dehydrogenase activity. The better nutrient management leads to better crop productivity which results in incorporation of larger organic matter through root biomass or leaf fall, root exudates, etc. thereby influencing the C dynamics in soil. The nutrient level and moisture play a dominant positive role towards the dehydrogenase activity. The dehydrogenase activity and biomass carbon content tended to increase with the advancement in crop growth. The results from the correlation analysis have revealed that the soil nutrient status has a direct and significant role in enhancing the soil microbial and enzyme activities. Integrated use of inorganic fertilizers, Sesbania aculeata and Azolla orchestrates soil nutrient availability, biomass production, biochemical activities and favorable soil physical environment that facilitate effective carbon sequestration in lowland rice ecosystem. |
