Abstract
In one aspect, the present subject matter is directed to a method for maintaining a desired amount of residue coverage in a field during a tillage operation. The method includes generating, with a computing device, an available residue map that includes an amount of available residue at each location of the field using a yield map and/or crop biomass. The method also includes generating, with the computing device, a desired residue coverage map that includes a desired amount of residue coverage for each location within the field. Further, the method includes determining, with the computing device, an amount of residue that needs to be incorporated into the surface of the field based on the available residue map and the desired residue coverage map. Moreover, the method includes generating, with the computing device, a prescription map for the field based on a correlation between a tillage parameter of one or more ground-engaging tools of the implement and the amount of residue that needs to be incorporated into the surface of the field. In addition, the method includes controlling the tillage parameter based on the prescription map during the tillage operation to maintain the desir…
