Description

Subsurface drainage systems have been intensively installed in the Midwest to enhance agricultural production by removing excess water from naturally poorly drained and somewhat poorly drained agricultural soils. However, despite positive aspects, numerous studies have reported artificial subsurface drainage as one of the primary pathways for nitrate-nitrogen (nitrate-N) loss from agricultural fields to surface water.
