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 desired amount of residue coverage at each of the locations in the field.

First claim

What is claimed is:

1. A method for maintaining a desired amount of residue coverage in a field during a tillage operation, the method comprising:
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;
generating, with the computing device, a desired residue coverage map that includes a desired amount of residue coverage for each location within the field;
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;
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; and
controlling the tillage parameter based on the prescription map during the tillage operation to maintain the desired amount of residue coverage at each of the locations in the field.

2. The method of claim 1 , further comprising generating the yield map for the field or determining the crop biomass based on a relationship between crop yield of the field and the amount of residue on the surface of the field, the yield map or the crop biomass indicating crop yield at each of the locations within the field.

3. The method of claim 1 , wherein the tillage parameter comprises at least one of a penetration depth or a down pressure associated with the one or more ground-engaging tools.

4. The method of claim 3 , wherein the correlation comprises increased penetration depths corresponding to more residue being incorporated into the surface of the field and lesser penetration depths corresponding to less residue being incorporated into the surface of the field.

5. The method of claim 1 , further comprising determining the desired residue coverage map based on at least one of a digital elevation map, elevation data of the field, soil type and/or texture, or soil compaction levels.

6. The method of claim 1 , wherein the one or more ground-engaging tools comprise, at least, one or more front disk gangs.

7. The method of claim 6 , further comprising separately controlling one or more of the penetration depths of the one or more front disk gangs from other ground-engaging tools.

8. The method of claim 1 , further comprising generating the prescription map for the field based on the correlation between the tillage parameter of one or more ground-engaging tools of the implement, the amount of residue that needs to be incorporated into the surface at each of the locations within the field, and at least one additional parameter, the at least one additional parameter comprising at least one of clod size, soil type and/or texture, or moisture content.

9. The method of claim 1 , wherein controlling the tillage parameter based on the prescription map during the tillage operation to maintain the desired amount of residue coverage at each of the locations in the field further comprises actively adjusting, with the computing device, the tillage parameter of the one or more ground-engaging tools of the implement according to the prescription map to ensure that the desired amount of residue coverage is maintained at each of the locations in the field.

10. A method for generating a prescription map for maintaining a desired amount of residue coverage in a field during a tillage operation, the method comprising:
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;
generating, with the computing device, a desired residue coverage map that includes a desired amount of residue coverage for each location within the field;
generating, with the computing device, a residue incorporation map that includes an amount of residue that needs to be incorporated into each location of the field based on the available residue map and the desired residue coverage map;
generating, with the computing device, a prescription map for the field based on a correlation between a penetration depth of one or more ground-engaging tools of the implement and the residue incorporation map; and
storing the prescription map into at least one of a vehicle controller of a work vehicle or an implement controller of an implement for use during the tillage operation to maintain the desired amount of residue coverage at each of the locations in the field.

11. The method of claim 10 , further comprising generating the yield map for the field or determining the crop biomass based on a relationship between crop yield of the field and the amount of residue on the surface of the field, the yield map or the crop biomass indicating crop yield at each of the locations within the field.

12. A system for maintaining a desired amount of residue coverage in a field during a tillage operation, the system comprising:
at least one controller for controlling a work vehicle and an implement during the tillage operation, the controller comprising at least one processor and associated memory, the memory storing instructions that, when implemented by the processor, configure the controller to perform one or more operations, the one or more operations comprising:
generating 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;
generating a desired residue coverage map that includes a desired amount of residue coverage for each location within the field;
determining 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;
generating 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 amount of residue that needs to be incorporated into the surface of the field; and
storing the prescription map in the memory for use during the tillage operation to maintain the desired amount of residue coverage at each of the locations in the field.

13. The system of claim 12 , wherein the one or more operations further comprise generating the yield map for the field or determining the crop biomass based on a relationship between crop yield of the field and the amount of residue on the surface of the field, the yield map or the crop biomass indicating crop yield at each of the locations within the field.

14. The system of claim 12 , wherein the one or more operations further comprise determining the desired residue coverage map based on at least one of a digital elevation map, elevation data of the field, soil type and/or texture, or soil compaction levels.
