Resumen
While the perceived magnitude of ephemeral gully
erosion may be masked after gullies are repaired, the action
of plowing in these channels reduces topsoil thickness and
crop productivity over a much wider area than the channel
itself. This study demonstrates that filling ephemeral gullies
on an annual basis during tillage operations may be more
destructive than realized. These results shoul ...

While the perceived magnitude of ephemeral gully
erosion may be masked after gullies are repaired, the action
of plowing in these channels reduces topsoil thickness and
crop productivity over a much wider area than the channel

destructive than realized. These results should provide land
managers an additional incentive for adopting soil
conservation practices such as no-till. [--]
