Wing-Chisel Plow for In-Row Conservation Tillage
1988
Heilman, M. D. | Valco, T. D.
Conservation tillage in the semiarid subtropical region of South Texas should both maintain soil moisture and reduce wind erosion. Farming in the area historically uses seven to 10 tillage operations to prepare land for planting. The newly developed wing-chisel has been effective in the once-over desiccation of stubble from recently harvested crops. Additional benefits have included deep tillage to break any existing hardpan, controlled tractor traffic by using the chisel as an in-row implement for a ridge-till planting configuration, increased infilatration rates, and maintaining plant residue on soil surface. The plow, which is simple in design, when added to either disc or lister bedders becomes a once-over tillage implement that accomplishes all necessary soil preparation between harvest and planting. Winter weed control between grain harvest and planting is accomplished by the use of contact herbicides. Contribution from the USDA-ARS, Conservation and Production Systems Res.
