Spatial variability of soil organic matter content in an arid desert area
干旱荒漠区土壤有机质空间变异特征

Alxa Left Banner in the west of the Inner Mongolia Autonomous Region, China, is a typical arid desert area in the middle temperate zone between the northern border of China and the eastern Alxa Plateau. Due to overgrazing and human activities, soil degradation (or desertification) in the area is becoming increasingly severe due to loss of soil organic matter (SOM). Low SOM content impacts soil quality directly in this arid desert area. Understanding the spatial variation and distribution pattern of SOM cont...
