9. The system of claim 1 , wherein the inefficiency associated with the application session includes an area of the field to be overlapped by the applicator during the application session, an area outside of the field to be covered by the applicator during the application session, or an area of the field associated with a reduced speed of the vehicle during the application session.
10. A method of controlling an agricultural application rate, the method comprising:
determining an area of a field to be covered during an application session;
determining an amount of product to be utilized during the application session based on an amount of product on a vehicle and a final product amount to be remaining on the vehicle after covering the field;
determining an inefficiency associated with the application session based on at least one of a path for the vehicle, a boundary of the field, the area of the field, elevation changes in the field, or application characteristics associated with an applicator operatively coupled to the vehicle; and
determining an initial application rate before starting to cover the field based on the amount of product to be utilized during the application session, the area of the field to be covered during the application session, and the inefficiency associated with the application session.
11. The method of claim 10 , further including determining a remaining area of the field to be covered in response to the area of the field being at least partially covered.
12. The method of claim 11 , further including:
determining a remaining amount of product to be utilized; and
determining whether the initial application rate over the remaining area of the field results in the amount of product to be utilized during the application session based on the remaining amount of product and the remaining area of the field.
13. The method of claim 12 , further including determining a second application rate for the remaining area of the field in response to the initial application rate over the remaining area of the field not resulting in the amount of product to be utilized during the application session.
14. The method of claim 10 , further including determining the boundary of the field to be covered, the area of the field to be covered during the application session based on the boundary of the field.
15. The method of claim 10 , further including determining the path for the vehicle to follow during the application session.
16. One or more non-transitory computer readable media comprising instructions which, when executed, cause one or more processors to at least:
determine an area of a field to be covered during an application session;
determine an amount of product to be utilized during the application session based on an amount of product on a vehicle and a final product amount to be remaining on the vehicle after covering the field;
determine an inefficiency associated with the application session based on at least one of a guidance path for the vehicle, a boundary of the field, the area of the field, elevation changes in the field, or application characteristics associated with an applicator operatively coupled to the vehicle; and
calculate an initial application rate in advance of starting to cover the field based on the amount of product to be utilized during the application session, the area of the field to be covered during the application session, and the inefficiency associated with the application session.
