Abstract
Apparatus is disclosed which is adapted to form a series of angled depressions with raised sides in the row space between adjacent row lines of a row crop. The depressions and raised mounds between them are oriented at an acute angle relate to the row line, to present a generally uniform surface for subsequent farming operation which minimizes machine and operator jostling, while effectively retaining water where it falls, and nutrients, herbicides and the like where they are applied.
