Abstract: | The effect of forests clear felling and associated burning on the population of soil nitrogen transforming bacteria and actinomycetes
are reported at three pair sites of Chittagong University campus, Bangladesh in monsoon tropical climate. Clear felled area
or burnt site and 15–21 year mixed plantation of native and exotic species, situated side by side on low hill having Typic
Dystrochrepts soil was represented at each pair site. At all the three pair sites, clear felled area or burnt site showed
very significantly (p≤0.001) lower population of actinomycetes, Rhizobium, Nitrosomonas, Nitrobacter and ammonifying as well as denitrifying bacteria compared to their adjacent mixed plantation. From environmental consideration,
this finding has implication in managing natural ecosystem. |
