258 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2006.Double mass curve analysis indicated that the increase of nutrient and herbicide loading began when high amounts of rainfall occurred following chemical application. The primary factor that was found to affect nutrient and herbicide loading was subsurface flow, especially during the growing seasons.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
