摘要：

Previous studies have focused on carbon (C) and nitrogen (N) stocks of soils because of increases in atmospheric carbon dioxide (CO2) and terrestrial ecosystems with wide N storages. The goal of this study was to determine C amounts and stocks that are important for global warming, N amounts and stocks and C:N ratios. To this end, 16 series were opened on the Harran Plain and soil samples were taken from 100 cm depth and each horizon. The results showed that total carbon amounts varied between 0.80 and 1.85 kg C m(-2). N amounts were between 0.16 and 0.34 kg N m(-2), C:N ratios were between 4.32:1 and 6.04:1 and bulk density (BD) was 1.23-1.34 Mg m(-3). Carbon and N stocks were determined as 10.53 Tg C and 1.96 Tg N, respectively.
