Most of it happens in virtual space on design software and lately online. Subsurface tile drainage systems can convey soluble nitrate nitrogen n from the crop root zone. The drainage coefficient is the water draining capacity of the drainage system and is typically expressed as a depth of water removed from soil in 24 hours inches day.

To design the tile drainage system for the field. Checks the capacity of drain tile on existing drainage systems. Adding perennial crops to the rotation may also reduce n losses to surface waters in addition to decreasing water drainage.
