What factors affect erosion rate? What is the relationship between climate and crop yield? How do plants and types of farming affect soil quality? This model is divided into two zones that allow you to compare different slopes and/or land management plans. The erosion rate graph shows the amount the soil in each zone moves in each measurement period. The topsoil graph shows you the amount of topsoil in each zone over time.
