Ephemeral gullies sometimes are described as silent erosion because they can be easily smoothed over, hidden and planted to crops. Discing an ephemeral gully leaves nutrient rich topsoil vulnerable to erosion. Gully erosion is not a process limited to badlands, mountainous and hilly regions but a global and serious cause of land degradation affecting a wide variety of soils prone to crusting and/or piping.
