Weed Control Suitable weed control may be the most challenging facet of no-till systems. Because of the lack of tillage for chemical incorporating, herbicide choices are more limited than with conventional tillage. Lack of tillage also permits weed growth to begin before crop growth, sometimes making a chemical burndown treatment necessary. Preemergence and postemergence herbicides are available to control most weeds in corn and soybeans. Special weed control strategies, differing from conventional systems, must be applied.
Major benefits are increased soil conservation and potential for reduced input costs.
Yield potential depends greatly upon soil conditions and strict attention to appropriate management practices. In appropriate soil conditions, no-till can be an excellent choice for soil conservation in a row crop system.
