Subsurface Drainage

A properly designed subsurface drainage system removes the excess water from the root zone in a timely manner to prevent the crop from being under stress.

This requires the drainage lines in the field to be properly spaced. The spacing of the drainage lines is dependent on the permeability of the soil. The lower the permeability, the closer the drainage lines are spaced. It is also necessary for the drainage lines to be installed with grade (slope). This is critical to the operation of the system. Subsurface drainage systems typically don't require the level of maintenance that a surface drainage system requires.
