Drainage water quality impacts of current and future agricultural management practicesLeopold Center Completed Grant Reports
AbstractResearchers examined how crop tillage, rotation or crop residue removal can affect the chemical composition of water draining from farm fields.
Key QuestionHow do nutrient management practices influence nitrate-N loss in subsurface drainage?
FindingsA multi-year, replicated plot subsurface drainage study monitored drainage water and crop yield. Cover crops have the potential to reduce nitrate loss and increased application of nitrogen in a corn-soybean or continuous corn system has the potential to increase nitrate loss.
