Abstract: The effects of systematic compost addition or cover cropping throughout the agricultural land of the Foggia province (Southern Italy) on the soil organic carbon (SOC) stocks and the CO2-C emissions were predicted over a period of 20 years (1994-2013). Therefore, the bio-physical model RothC10N was used in combination with spatially explicit input data including soil types, soil textures, land use and climate. Actual crop successions and crop types on a grid with a resolution of 30-arc sec (1 km at the equator) were included in the input data. Compost application and cover cropping were not adopted as a general input to all soils and land use classes, but according to applicability in the particular cropping systems, therefore representing a realistic input scenario under given soil use practices in the area. The results of the modelling process were spatialized with regression kriging, using soil maps, land use maps and satellite images as co-variates. While the control scenario led to a SOC depletion of 0.81 Tg and a total CO2-C emission of 21.1 Tg over 20 years in the Foggia province, systematic compost addition could reduce the loss of SOC to 0.56 Tg C while slightly increasing CO2-C emissions to 21.6 of Tg C. Cover cropping led to an overall SOC accumulation of 0.61 Tg and cumulated CO2-C emissions of 24.6 of Tg. Cover cropping therefore represents the most promising tool for carbon sequestration in the Foggia province.
