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. Anticipated Problem: . What is soil erosion?. I. . Soil erosion . is the process by which soil is moved. When soil is eroded, it may become pollution in the water or air. The land where it came from, loses fertility. Vegetation and other coverings help prevent soil erosion. . Chad Lentz. Why Care?. Removes valuable topsoil. Carries away expensive nutrients. Increase tillage costs to fix. Creates algae blooms and dead zones due to excess nutrients in waterways. Types of Erosion. Chapter 7. Section 7.1 Weathering.
