Abstract

ABSTRACT: Spatiotemporal assessment of the mangrove soil of Indian Sundarban revealed that decomposition rate of the organic matter was significantly lower in the anoxic condition than that of the oxic condition. Higher degree of enzyme activity in the oxic soil than the anoxic condition suggested that slower biomineralization in anoxic condition would facilitate long-term storage of organic matter in that particular ecosystem. Microbial population of nitrifying bacteria, phosphate solubilizing bacteria, cellulose degrading bacteria and fungi showed significant reduction in anoxic incubation than that in oxic incubation. In contrary, sulfate reducing bacteria and free living N2 fixing bacteria showed higher population in anoxic incubation indicating their preference for anaerobic condition. Soil CO2 emission rate decreased with the increase in anoxicity and was largely dependent on the soil redox potential, organic carbon and microbial population of the mangrove soil.
