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. 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. . Taylor Creek Park Rehabilitation.

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. Physical Weathering. Weathering. is the breakdown of rock or soil. . Physical . weathering occurs when natural forces, such as wind, running water, and moving ice, physically break up rock and soil into smaller particles. . Chapter 7. Section 7.1 Weathering. Weathering is the process by which rocks on or near Earth’s surface break down and change. . Erosion is the removal and transport of weathered material from one location to another.. Nancy . Rogel.
