Effect of Salix cupularis shrubs on soil nitrogen in the alpine sandy land of Northwest Sichuan

doi:10.11686/cyxb2016343

Abstract

Abstract: In this study, we evaluated the effect of Salix cupularis shrubs on the spatial heterogeneity of soil nitrogen, soil water content, and soil pH in the alpine sandy land of Northwest Sichuan, China. The soil water content was higher inside shrub canopies than outside. However, the soil pH was higher outside of shrub canopies than inside. Soil total nitrogen, available nitrogen, ammonium nitrogen, and nitrate nitrogen contents were significantly higher inside the shrub canopies than outside (P<0.05). Soil nitrite nitrogen was higher outside of shrub canopies than inside. These results indicate that the presence and distribution of S. cupularis shrubs can affect the nutrient patterns in soil.
