Soil Organic Carbon Stock (SOCS) in Eutrophic and Saline Ramsar Wetlands in Serbia

Popis výsledku v původním jazyce

Wetlands store large amounts of soil organic carbon stock (SOCS), making them crucial for global climate regulation. However, climate change, poor management, and weak protection policies threaten these stocks. To assess the contribution of different wetland types for national and international climate targets and to monitor the effectiveness of protection measures, additional research is required. Therefore, we assessed SOCS and disturbances from climate change, land use/land cover (LULC), and soil chemical composition in saline and eutrophic Ramsar sites in Serbia. Analyzing a total of 96 samples, we accounted for soil depth, reference soil group (RSG), and habitat/vegetation type. Mean SOCS in the saline site ranged from approximately 36 t&lt;middle dot&gt;ha-1 at 0-30 cm to 26 t&lt;middle dot&gt;ha-1 at 30-60 cm, whereas values were much higher for the eutrophic sites, ranging from 81 to 82 t&lt;middle dot&gt;ha-1 at 0-30 cm and 47-63 t&lt;middle dot&gt;ha-1 at 30-60 cm. Differences between groups for the whole soil columns (0-60 cm) were significant at the 0.1% level. While SOCS generally decreases with depth, it showed notable local variability, including occasional instances at deeper layers, indicating complex environmental and anthropogenic influences. Spatial mapping of soil chemistry parameters (pH, humus, P2O5, and K2O) along with land use/land cover (LULC) data revealed nutrient dynamics influenced by agricultural activities. An analysis of regional climate data revealed temperature increases relative to the reference period of 1971-2000 by 0.5 degrees C for the decade 2001-2010 and of 1.5 degrees C for 2011-2020. Climate projections under the RCP4.5 and 8.5 scenarios predict further warming trends, as well as increased rainfall variability and drought risks. The results of our study contribute to quantifying the important, though variable, contribution of wetland sites to global climate regulation and show the influence of geogenic, pedogenic, and anthropogenic factors on SOCS. National policies should be adapted to safeguard these stocks and to limit negative effects from surrounding agricultural areas, as well as to develop strategies to cope with expected regional climate change effects.
