Resource Description

Objectives for this study were to quantify growing season subsurface drainage water flow, nitrate nitrogen concentrations, and nitrate nitrogen loads for conventional and organic grain cropping systems from 2012-2014. Results of this study suggest that organic farming practices, such as the application of composted animal manure and the use of forage legumes and green manures within extended cropping rotations, can improve water quality in Midwestern subsurface-drained landscapes.
