Abstract Estimated critical limits of selected soil parameters for evaluating tillage requirements for corn in the water management (interrow) zone and seedling environment (row) zone are presented. Suggested parameters for corn in the western Cornbelt for the row zone include soil temperature, secondary aggregate size, bulk density and volume of the zone. For the interrow zone, the parameters include depression storage, plow layer storage, and/or surface mulch or surface microrelief. The research basis for the selection of the critical limits and soil parameters is discussed. This approach can be used to evaluate tillage needs for other crops.
