Weeds compete with corn plants for water, nutrients and light. Historically, the soil has been extensively tilled to prepare a seedbed and to lessen or remove weed competition. This tillage centered around moldboard plowing.
Results of a recent survey indicate that most Nebraska farmers now use some form of reduced tillage, with the moldboard plow being used on only 11 percent of Nebraska's corn acreage. Reduced tillage is used in many forms.
This NebGuide discusses how to control weeds using the different types of tillage systems.
