| description | Abstract Forest fire is one of the prominent factors for soil organic carbon (SOC) stock variation across forest types as well as within the same habitat. Assessing the impacts of current fire frequency will provide useful insight into the extent of potential changes in SOC associated with increasing fire frequency as projected for the near future. The present study was carried out to assess the impacts of fire frequency on the soil organic carbon stock by preparing a fire frequency map using Landsat satellite image and collecting data by field sampling and laboratory analysis for each fire frequency class. Results showed that total SOC stock varied from 11.98 ± 2.7 to 26.15 ± 6.4 Mg C ha− 1, being highest in unburned areas and lowest in areas with very high recurrent fires. Further, a strong monotonic decline in total SOC stock with increasing fire frequency was observed, with a significant variation of 54.19% in between unburned and highly burned fire frequency classes, indicating a gradual negative effect of recurrent fires on SOC stock. Structural equation model clearly indicated a fire frequency induced decrease in SOC stock both directly and indirectly and the indirect impact was through taxonomic diversity. In the present study, the loss of SOC stock with increasing fire frequency was more for the 0–10 cm layer of soil rather than 20–30 cm of soil layer. No impact of fire frequency on bulk density was observed in all fire frequency classes. Data generated in the present study would add more to the existing knowledge. It would be helpful for development of more sustainable frameworks and effective management of forests in tropical moist deciduous forests to mitigate the present-day crisis of climate change. |
