ZONE TILLAGE - A restricted tillage system that estab- lishes a narrow (4-6-inch) band of loosened soil with surface residues removed. This is accomplished using multiple coulters and row cleaners as attachments on a planter. It may include a separate "zone-building" practice that provides deep, narrow ripping without significant surface disturbance. It is a modification of no tillage, generally better adapted to cold and wet soils.
