Description :
Water dispersible clay (WDC) is a good indicator of the risk of soil erosion by water and the consequent losses of nutrients and contaminants in overland flow. The AA. measured the content and studied the properties of WDC in 26 samples of calcareous Xeralfs, Xerepts and Xererts of southwestern Spain collected from fields under different crop and tillage management. Results and discussion on : soil properties; properties of the clay fractions; water dispersible clay; phosphorus in water dispersible clay.
