Abstract

Conservation tillage (CT) has had more impact on weed control in row crop production than any other recent change in management practices. In conventional tillage systems, moldboard plowing and secondary tillage just before planting help crop seedlings get an equal start with weed seedlings. In CT systems, herbicides are used to substitute for some or all of this tillage.
