How Do You Control Gully Erosion In Clay Soil?
Gullies are typically caused by increased rates and intensity of surface runoff. Unchecked rill erosion may evolve into this more substantial form, which can result from poor land-use management and is exacerbated by natural processes. Clay soils are generally less resilient than sand- and loam-based ones, and because clay minerals bind to water molecules, their loss can reduce the moisture-holding capacity of the soil and perpetuate the erosive cycle. Prevent gullies before they arise. This is much easier than attempting to control them once they’ve formed, when climatic, geological and fluvial processes sometimes collude in perfect conditions for their enlargement. For example, where gullies start in areas of fragile clay subsoil atop decomposed granite, great U-shaped channels over a hundred feet deep may eventually develop. Such mammoth scours can be subject to landslides, especially in the face of storms and weather-related phenomena. Proper land use—maintaining stabilizing vege
