The theoretical basis or aim of my research project is to determine the likely cause of the observed variance in soil texture along a slope gradient in a grassland ecosystem. The theory that I am exploring and forms the parameters for my field data collection include, slope gradient and vegetation type and cover as possible explanatory factors for the observed variance in soil texture. Ideas that underpin my research include the understanding the gravity & water transport finer soil particles further away from steep slope positions then coarser soil particles. Another idea is the role that vegetation plays in determining soil texture in a given site.
Keywords: Soil texture, slope gradient, grassland ecosystem.
