Effect of environmental factors on regional soil organic carbon stocks across the Loess Plateau region, China

► An intensive sampling of soils across the entire Loess Plateau region in China was conducted to determine soil organic carbon levels in upper (0–40 cm) and deeper (0–200 cm) soil layers. ► Geostatistical analysis and kriging was used to create a continuous surface across the region for soil organi...

Zusammenfassung:	► An intensive sampling of soils across the entire Loess Plateau region in China was conducted to determine soil organic carbon levels in upper (0–40 cm) and deeper (0–200 cm) soil layers. ► Geostatistical analysis and kriging was used to create a continuous surface across the region for soil organic carbon density for the upper soil layers. ► Relationships between environmental factors (i.e., precipitation, temperature, elevation, slope gradient, clay and silt contents (
