PEDO-ECOLOGICAL SIGNIFICANCE OF SOIL ORGANIC CARBON STOCK IN SOUTH-EASTERN PANNONIAN BASIN


Full text

The aim of this research is to examine soil organic carbon (SOC) stock in the South-eastern Panonnian Basin. For estimating the SOC stock 10 different soil types were accessed with 400 soilprofiles representing different locations in Vojvodina at 0-30, 30-60 and 60-100 cm depths. Three factorswere taken into  consideration, soil type being the one with the largest influence on the SOC content. Datacollected were plotted on a map by using the Ordinary Kriging method. The results showed differencesbetween soil types and soil depths. At 0-100 cm soil depth, the highest SOC levels were found inRegosols, Vertisols, Gleysols and Chernozems and the lowest in Solonchaks, Fluvisols and Arenosols. Onthe total of 1,807,073 ha examined, the SOC reserves at 0-30 cm depth were estimated to 122 Мt,whereas total stock in 0-100 cm soil layer was 270 Мt. The results obtained could be valuable formonitoring SOC change and to recommend measures for the conservation of SOC.
