Agriculture Deputy Secretary Kathleen Merrigan today announced that soil erosion on cropland declined by more than 40 percent during the past 25 years, while more than one-third of all development of ...
Hilly-Land Soil Loss Equation (HSLE) for Evaluation of Soil Erosion Caused by the Abandonment of Agricultural Practices
potential soil erosion shallow groundwater
2009/9/9
Soil erosion from fields located in the hilly lands of Shikoku was investigated. These are the areas where agricultural practices are quite limited and fields are often left idle and unutilized. Based...
Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion chan...
Effectiveness of exclosures to control soil erosion and local community perception on soil erosion in Tigray, Ethiopia
Ethiopia exclosures local experts perception rural community soil erosion
2010/9/10
The study investigated how effective exclosures are in the fight against soil erosion and how they are perceived as a means to control soil erosion by the local community (farmers and local experts). ...
