How do plant roots overcome physical barriers
WebInfluence of Vegetation and the Impact of Rain on Soil. Vegetation intercepts rain, reducing its energy and preventing splash erosion. It also slows runoff, reduces sheet erosion, and anchors and reinforces the soil with its root system. Figure 2 shows how erosion rate decreases as the soil is covered by vegetation.
