Abstract
A method of shaping furrows in soil includes the steps of: determining existing elevation profiles for a plurality of existing furrows in a geographic unit; establishing a target elevation profile for each of the existing furrows; and moving soil laterally either toward or away from one or both side walls along a length of each furrow to achieve the target elevation profiles within the geographic unit.
