Sažetak
Soils are the largest carbon reservoir of the terrestrial carbon cycle. The quantity of C stored in soils is highly significant ; soils contain about three times more C than vegetation and twice as much as that which is present in the atmosphere. Proper management of soil carbon requires an understanding of the cycling and balance of carbon. Soils vary greatly in their organic matter content. Soil organic matter consists of two groups of compounds, nonhumic and humic substances, both play important roles in the environment affecting the biochemical, physical and chemical properties of soil. Within Bilateral Project between Hungarian and Croatian scientists “Impact of tillage and fertilization on probable climate threats in Hungary and Croatia, soil vulnerability and protection” carbon storage were determined in different soil types in agroecological conditions of Pannonian plain and in Mediterranean. Total carbon content, pH and CN ratio in different natural (grasslands, meadows, forests) and agro ecosystems (vineyards, gardens and crop fields) were determined. Soil samples were taken during the spring and summer 2010 at different locations. Sampling depths varied from 0-3 cm, 3-10 cm, 0-30 cm, 30-60 cm and 60-90 cm depending on the location, region, soil type and type of ecosystem. At 15 different locations, 5 in Pannonian plain and 10 in Mediterranean following results are recorded: soil pH (in 1 M KCl, 1:2.5 (w/v)) varied between 5.0 measured at Mediterranean pasuture and 7.6 recorded in a crop field of Pannonian plain on Chernozem ; CN ratio varied from 11 up to 39 noted in Mediterranean vineyard on Cambisol calcaric ; carbon content observed in this study varied from 3.3 g C/kg measured in Szentgal at agricultural crop field on Eutric Cambisol in deeper layers (< 60 cm) up to 107.2 g C/kg measured at Mediterranean grassland in surface layer (0-3 cm).
