The Causes and Effects of Soil Erosion, and How to Prevent It

Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding. Once soil erosion occurs, it is more likely to happen again.A Ground Stone Implement Quarry on the Lower Colorado River bracing rocks, and punches.
