Each year tons of soil erode from cropland, pastures, forests, and other places. The amount of erosion varies dramatically among various land-use types. The figure above shows the effects of different agricultural practices and slopes on annual erosion rates. (a) Refer to the graph above for the following. (1) Identify the scientific question that resulted in the data presented in the graph. (H) Identify the agricultural practice that could be used on a 15% slope without leading to a higher than tolerable loss of soil CID Ressribe the effect of adding a cover crop compared to using the no-till method.
