Fig. 2From: Soil erosion affects variations of soil organic carbon and soil respiration along a slope in Northeast ChinaSOC depth distribution (a) and stocks (b) as a function of the geomorphic position. Statistical tests for differences between the means of the geomorphic classes have been performed for the entire dataset and for top and subsoil samples separately. The same letter indicates no significant difference between the geomorphic positions (p < 0.1)Back to article page
