“…Carbon storage in forest soil refers to the process of sequestering or storing carbon in the soil of forest ecosystems. Forest soils contain plant roots, foliar litter, and other dissolved organic material, which can store carbon (Menyailo, 2022). The amount of carbon soil can sequester is dependent on many local factors like local geology, soil type, vegetation and moisture regime.…”

The scope of the study is to evaluate soil greenhouse gas (GHG) fluxes from drained and naturally wet (pristine) nutrient rich mineral forest soils representing Mercurialosa mel. (drained) and Myrtillosoi-polytrichosa and Drypteriosa (wet soil) forest stand types with dominant species (aspen, birch and black alder). GHG were monitored during 12 months period using opaque chamber method. Gas samples were collected once per month and carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) concentration was determined using gas chromatography. The calculated GHG fluxes were evaluated in conjunction with temperature, soil moisture and groundwater level measurement results. We did not found difference of the soil GHG fluxes in drained and pristine wet mineral soils. The N2O and CH4 emissions from soil are negligible; however, periodic extreme increase of CH4 is characteristic for pristine wet soils, pointing out that wet mineral soils can be significant source of GHG emissions, just like organic soils. CO2 emissions are correlating with air and soil temperature, while CH4 and N2O emissions are not correlating with any of the monitored environmental variables.

Lower Sensitivity of Soil Carbon and Nitrogen to Regional Temperature Change in Karst Forests Than in Non-Karst Forests

Lithology has such an important effect on the sustainability of soil carbon (C) pools. Forests are an important part of terrestrial C sinks; yet, it is unclear whether their soil carbon sensitivity to temperature changes is regulated by lithology, especially in karst ecosystems, which are widely distributed globally. Along a climate gradient in the subtropical region of southwest China, we compared the contents of soil organic C (SOC) and total N (TN) in karst and non-karst forests. The data were analyzed and processed using ANOVA, regression analysis, and random forest. The results showed that the karst forests had significantly higher SOC and TN contents but lower ratio of SOC to TN (C:N) than non-karst forests, mainly because of the higher soil calcium (Ca) content and microbial biomass. With rising mean annual temperature (MAT), SOC and TN contents in non-karst forests significantly decreased, whereas in karst forests they were not correlated with MAT; while, the opposite was true for C:N. In karst forests, soil Ca constrain warming induced decomposition of SOC and TN by forming stable complexes with SOM through exchangeable Ca, and by promoting aggregate stability through the role of calcium carbonate. The correlation between δ13C and the logarithm of SOC concentration also supported that conclusion. In karst forests compared to non-karst forests, soil C pools are larger and less sensitive to regional temperature change. Nevertheless, climate warming may still accelerate soil C loss in karst forests by increasing microbial C limitation. Thus, soil C sequestration potential and loss risk coexist in karst areas. The ratio of SOC to TN (C:N) is regulated through appropriate management measures in the process of karst vegetation restoration, thus promoting long-term stable sequestration of soil carbon pools.
