ABSTRACT:
One externality of soil loss from cropland is sedimentation of drainage ditches. Such sediment deposits in six Ohio counties related significantly to gross soil erosion estimates calculated with the universal soil loss equation. Removal of the sediment cost an average of 45 cents per cropland acre served by the drainage ditches. This cost could be reduced nearly 25 percent with the use of common soil conservation practices.
