Tillage destroys soil structure and reduces the residue cover, leaving the soil surface more prone to erosion and runoff. While the tillage does fill in the gully, each time the gully washes out again, the soil is lost from the gully and from along the sides of the gully as that soil was used to repair the gully. 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.
