- W4322020110 abstract "​ Better knowledge of the amount and spatial distribution of soil organic carbon (SOC) stock at national level is a key element for monitoring, planning and decision-making regarding soil quality management, agriculture or carbon storage options. The present study proposed a new digital soil mapping (DSM) initiative to map SOC stocks in Tunisian topsoils (0-30 cm) at 100 m resolution, using a Quantile Regression Forest algorithm and a national database of 1540 SOC stock profiles. Our results showed that the new prediction of SOC stocks outperformed global DSM products such as SoilGrids2.0 in both R² (0.44 vs 0.15) and RMSE (1.94 vs 2.52 kg m-2). It provided an updated assessment of the SOC stock on the Tunisian territory at 391Tg C in the first 30 cm of soil profile, i.e. an average of 2.53 kg m-2. The importance of the environmental covariates tested indicates the major role of bioclimatic data and, to a lesser extent, remote sensing images and topography-related variables. Our study did not show a significant added value of using additional covariates in relation to nationally available variables or the SOC map predicted by SoilGrids2.0. Future improvements should focus on additional field surveys and exploration of new covariates through sub-national approaches, starting with the northern region of Tunisia, which has the highest SOC stock predictions and uncertainties in the country." @default.
