Title: Effects of Land Use Types on Soil Fertility in Xizhuang Watershed
Abstract: Soil physical and chemical properties under the four main types of land use (forest land, farmland, tea garden and bush land) in the Xizhuang watershed, Baoshan, Yunnan province, has been studied through field soil sampling and laboratory analysis. Effects of different land use types on soil fertility have been discussed in this paper. The results show that the different land uses will have obvious effects on soil fertility. Both soil organic matter and total nitrogen content decline in a sequences from bush land, forest land and tea garden to farm land; phosphorus and potassium content decline in a sequences from farmland, tea garden and forest land to bush land; cation exchange capacity (CEC) from farmland, tea garden and bush land to forest land; and base saturation percentage (BSP) from farm land, bush land and forest land to tea garden. Farming practices have significant impacts on the physical and chemical properties of topsoil.
