Effect of Agricultural Drainage on Water Quality in the Great Lakes and Cornbelt Statesby Norman R. Fausey, Soil Drainage Research Unit, Columbus, United States,
Abstract: The soils and the climate of the Great Lakes and Cornbelt states dictate that drainage is required to carry out economically viable farming activities. When drained, the soils are very productive and this region accounts for nearly 80 percent of the agricultural production of the United States. Drainage played an important role in the development of these areas and a historical perspective for the region is included to indicate the amount of drainage, the magnitude of the need and the amount of application. Specific research results related to the effects of agricultural drainage on water quality are summarized. Future needs and institutional and societal restraints and opportunities will be addressed.
