The conversion of forest to pastoral and agricultural management has important implications for carbon storage in soils. The stationary conditions of Neamtu catchment is characterized by an altitudinal difference between 270 - 1523 meters, 418 sq. km surface area, with notable differences of morpho-lithological, climatic, hydrological and biogeographical conditions reflected in both soil diversity and carbon content differences. This study aimed at calculating and comparing the estimated soil carbon stocks in different types of land use. The soil carbon stock (SCS) depends on forestry stations type, forest physio-climatic units, forests history and management. Moreover, the soil organic carbon stocks (SOC) were estimated using a mean value of 80 t C/ha for temperate forest and pastoral ecosystems while for agricultural the assigned mean was 50 t C/ha. The SCS trend expressed by the sequence of grassland soil>forest soil>cropland soil is a cause of the decreasing with 20% of SOC after grassland shifted to forest. The statistical analysis indicated a positively correlation of soil organic content with total nitrogen content.
