Wided Batita Ing PhD Geomatics Laval University Québec Canada 28 th April 2017 Outline Statement of the Problem Methodology amp Theoretical Orientation Findings. Soil erosion and sediment control is not a new technology The USDA Soil Conservation Service and a number of State and local agencies have been developing and promoting the use of erosion and sediment control devices for years This chapter provides Methods of soil conservation (ch3). The key aspects discussed in this chapter are:. Windbreaks. Contour ploughing. Stubble planting. Terraces. Stone walls. Reduce farming in dry weather. Windbreaks. Reforestation.
