Interrill erosion is the process of soil erosion that occurs on small. un-vegetated areas between ridges or furrows caused by raindrops falling on sloped land. The impact of raindrops can cause the soil to detach and be carried away by runoff. Interrill erosion can be a significant contributor to overall soil erosion and is considered a problem in agricultural areas. https://www.spidertattooz.com/USC-Trojans-9FIFTY-Snapback-Hat/
