Desertification is one of the most serious types of land degradation. A field experiment was conducted during 2002 and 2003 in Horqin Sand Land, China to investigate changes in soil C and N contents in relation to land desertification. Four primary results were derived from this work. First, land desertification characterized by wind erosion resulted in a significant decrease in soil fine particles...
A field experiment was conducted in the Horqin sandy grassland, where desertification intensity gradients could be utilized to evaluate C and N concentration and storage in plants, litter and soil relative to the degree of desertification. The results showed that (1) grassland desertification could result in significant decreases in soil carbon and nitrogen storage, but the decrease of carbon and...
To understand the status and roles of shrubs in recovery processes of desertified land in the semi-arid areas of China, we investigated the effects of shrub canopy on soil properties, organic litter, seed bank and understory herbaceous community properties in the Horqin Sand Land, Mongolia. The results showed that in shifting sand dunes, content of very fine sand, silt and clay, organic matter, total...
Wind erosion and accumulated sand are recognized as the primary forms of cropland desertification in the arid and semiarid region, Inner Mongolia. However, there is a lack of knowledge on the effects of wind erosion and accumulated sand on soil properties and crop growth properties in this region. A field experiment was conducted from 2001 to 2002 on desertified cropland with gradients of wind erosion...
