Carbon variability in some Hungarian and Croatian Soils

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 region. Total carbon content 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 16 different locations, 6 in Pannonian plain and 10 in Mediterranean region following results are recorded: CN ratio varied from 11 up to 39 determined 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).
