Title: Integrated soil, crop and water management system to abate herbicide and nitrate contamination of the Great Lakes: Nitrate
Author: Drury, C. F.; Tan, C. F.; Gaynor, J. D.; Welacky, T. W.
Abstract: In this study, the integrated management system incorporates water table control, reduced tillage and intercropping as sustainable soil management practices. Water table management regulates tile discharge to provide storage of rainfall water received after herbicide and fertilizer N application. Water and NO-3 can then be used by the crop during dry periods in the growing season which would otherwise have leached out of the root zone. Therefore, this system should reduce herbicide and NO-3 concentrations in drainage water. The water table control management can also be used for subirrigation during low rainfall periods.
