Title: Reduced chemical input systems for improved water quality
Author: McGovern, M. A.; Culley, J. L. B.; Hamil, A. S.
Abstract: Many farmers are using or experimenting with combined chemical and mechanical means of weed control. This study was established to determine whether such combined management practices can reduce the use of herbicides while maintaining the current level of corn yields.The following management practices were evaluated: 1)broadcast vs banded-over-the-row placement of nitrogen2)broadcast vs band vs slot placement of nitrogen to assess potential for improved plant uptake efficiencies3) herbicide persistence and movement as affected by soils and climates in the lower Great Lakes Basin (Windsor to Ottawa)4) agronomic benefits of reduced herbicide application by over the row banding with cultivation vs. broadcast herbicide only weed controland 5) whether there are any agronomic benefits due to mixing herbicide with 28% UAN solutions (weed and feed effect).
