Water erosion causes losses of soil that far exceed the rates of soil development and the on-site consequences affect agriculture by:
decreasing soil volume available for the plant root to exploit
selectively removing nutrients and organic matter
breaking up paddocks into physically smaller units.
Off-site effects relate to the sedimentation of creeks, rivers, estuaries and reservoirs, increased flooding, eutrophication, and the general (more)...
