Abstract
This on-farm experiment tested five different cropping systems with the potential to improve nitrate N management in the capture zones of community water supplies in the upper Midwest. Residual soil nitrate N concentrations were determined for each system in order to estimate the likelihood of nitrate N leaching from the system. An economic analysis also was conducted.
