This study evaluates the impact of land use change on the soil carbon stock in the Karasu region of Turkey which in the last two decades has undergone substantial deforestation to expand hazelnut plantations. Analysis of seasonal soil data indicated that the carbon content decreased rapidly with depth for both land uses. Statistical analyses indicated that the difference between the surface carbon stock (defined over 0-5cm depth) in agricultural and forested areas is statistically significant (Agricultural=1.74kg/m2, Forested=2.09kg/m2, p=0.014). On the other hand, the average carbon stocks estimated over the 0-1m depth were 12.36 and 12.12kg/m2 in forested and agricultural soils, respectively. The carbon stock (defined over 1m depth) in the two land uses were not significantly different which is attributed in part to the negative correlation between carbon stock and bulk density (-0.353, p<0.01). The soil carbon stock over the entire study area was mapped using a conditional kriging approach which jointly uses the collected soil carbon data and satellite-based land use images. Based on the kriging map, the spatially soil carbon stock (0-1m dept) ranged about 2kg/m2 in highly developed areas to more than 23kg/m2 in intensively cultivated areas as well as the averaged soil carbon stock (0-1m depth) was estimated as 10.4kg/m2.en1095-86302015227235ElsevierDeforestationGeographic information system (GIS)Geostatistical analysisLand use changeSoil carbon stockGeowissenschaftenBiowissenschaften, BiologieTechnikIngenieurwissenschaftenJournal Article10.1016/j.jenvman.2014.08.01725226862Other
