Question

Quizplus · Accepted Answer

When rainfall hits a naturally vegetated field, the plants absorb and retain some of the water, which reduces the amount of runoff and the sediment content. However, in a farm field, much of the rainwater runs off the bare soil and carries sediment and nutrients with it, resulting in more sediment-laden water. Therefore, runoff from farm fields is likely to be greater and more sediment-laden than that from naturally vegetated fields.
