Abstract

Controlled drainage has been shown to be an effective technique for reducing nitrate-nitrogen losses from artificially drained agricultural fields, in several regions of the U.S. Previous research on watertable management in Minnesota is limited to one study performed in the 1920's, aimed at reducing frost damage in the crop rootzone. This paper describes the concept and progress of a new research project for investigating the feasibility of controlled drainage in southern Minnesota for reducing nitrate losses. Modeling and field experimentation are employed to examine the hydrologic, water quality and economic effects of this practice for the region. Results of a preliminary simulation, conducted to ultimately derive a watertable management scenario for field experiments, are used to illustrate the effects of climatic variability on the impacts of controlled drainage in southern Minnesota.
