Abstract
Locations of seeds in a field can be identified. A material is applied to the field by an agricultural machine, based upon the seed locations. The placement of the material is detected and the agricultural machine is controlled.
Claims20
A method of controlling an agricultural work machine, the method comprising:
- identifying a reference location on an agricultural surface;
- identifying a target location on the agricultural surface based on the reference location;
- controlling, based on the target location, a material application system of the agricultural work machine to apply material to the agricultural surface;
- sensing a characteristic of the material;
- generating a material sensor signal indicative of the characteristic;
- identifying a location of the applied material based on the material sensor signal;
- generating a processing system output signal based on the location of the applied material and based on the reference location, the processing system output signal representing a relative location of the applied material to the reference location;
- identifying an action based on the relative location of the applied material to the reference location;
- and
- generating a control signal to perform the identified action.

A method of controlling an agricultural planting machine, the method comprising:
- identifying a reference position, indicative of a seed location, in an agricultural field;
- applying material based on the reference position;
- sensing a characteristic of the material;
- generating a material sensor signal indicative of the characteristic;
- identifying a location of the applied material on the agricultural field based on the material sensor signal;
- comparing the location of the applied material on the agricultural field to the reference position to identify a relative position of the applied material relative to the reference position;
- generating an output signal based on the relative position of the applied material relative to the reference position;
- identifying an action based on the output signal;
- and
- generating a control signal to perform the identified action.

A method of controlling an agricultural system, the method comprising:
- identifying a target location on an agricultural surface;
- applying material to the agricultural surface based on the target location and a detected location of a material applicator of the agricultural system relative to the agricultural surface;
- sensing a characteristic of the applied material;
- generating a material sensor signal indicative of the characteristic;
- identifying a material location of the applied material on the agricultural surface based on the material sensor signal;
- comparing the material location of the applied material on the agricultural surface to the target location on the agricultural surface to identify a relative location of the applied material on the agricultural surface relative to the target location on the agricultural surface;
- generating an output signal indicative of the relative location;
- and
- generating a control signal to control the agricultural system based on the output signal.
