Not AConversion of mangrove vegetation into rice cultivation is considerably enhanced
nowadays which adversely affects ecological sustainability. Soil microbial community is
one of the key indicators to monitor soil health in mangroves. Studies on the variations in
the microbial community within mangroves are plenty, whereas reports in mangroveconverted
paddy soils are scarce. Therefore, Biolog® eco-plate-based technique was
used in this study to assess soil microbial community in the Bhitarkanika (MB) and
Sundarban (MS) sub-humid tropical mangroves-converted paddy soil. The results
showed that significantly lower soil microbial biomass carbon and enzyme activities
were recorded in MB and MS compared to the NRRI (National Rice Research Institute)
paddy soil where continuous rice cultivation is being practiced conventionally since 1946
under the sub-humid tropical region. Biolog®-based average well color development
(AWCD) was found significantly lower in MS and MB compared to NRRI. Shannon–Weaver
and McIntosh indices followed the similar trends of AWCD. A biplot analysis indicated the
positive correlation of pH, available phosphorus, actinomycetes population, and phenolic
compound utilization under MS, whereas EC and phosphate-solubilizing bacteria were
positively correlated under MB. Compared to MS and MB, NRRI paddy soil harbored more
carbohydrate-utilizing microbes and showed a positive correlation with fluorescindiacetate,
dehydrogenase, and acid phosphatase. Overall, the present study
suggested that the conversion of the Sundarban and Bhitarkanika mangroves into rice
cultivation adversely affected the microbial diversity, thereby altering natural sustainability.vailable
