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.
Claims21
An agricultural system, comprising:
- a first material application system configured to apply a first material;
- a reference position identifier configured to identify a reference position on an agricultural surface corresponding to the first material;
- a second material application system configured to apply a second material based on the identified reference position, the second material of a different type than the first material;
- a material sensor configured to sense a characteristic of the second material and generate a material sensor signal indicative of the characteristic;
- a sensor signal processing system configured to identify a location of the second material based on the material sensor signal, identify a relationship between the location of the second material and the identified reference position, and generate a processing system output signal based on the identified relationship between the location of the second material and the identified reference position;
- an action identification system configured to identify an action based on the processing system output signal;
- and
- a control signal generation system configured to generate a control signal to perform the identified action.

An agricultural planting machine, comprising:
- a seed application system configured to apply seed;
- a reference position identifier configured to identify a reference position on an agricultural surface corresponding to the seed;
- a material application system configured to apply material based on the identified reference position, the material different than the seed;
- a material sensor configured to sense a characteristic of the material and generate a material sensor signal indicative of the characteristic;
- a sensor signal processing system configured to identify a location of the applied material based on the material sensor signal, identify a relationship between the location of the applied material and the identified reference position, and generate processing system output signal based on the identified relationship between the location of the applied material and the identified reference position;
- an action identification system configured to identify an action based on the processing system output signal;
- and
- a control signal generation system configured to generate a control signal to perform the identified action.
