Abstract
An agricultural harvesting machine includes crop processing functionality configured to engage crop in a field, perform a crop processing operation on the crop, and move the processed crop to a harvested crop repository, and a control system configured to identify a weed seed area indicating presence of weed seeds, and generate a control signal associated with a pre-emergence weed seed treatment operation based on the identified weed seed area.
Claims20
An agricultural harvesting machine comprising:
- crop processing functionality configured to engage crop in a field, perform a crop processing operation on the crop to obtain processed crop, and move the processed crop to a harvested crop repository;
- and
- a control system configured to:
- identify a weed seed area indicating presence of weed seeds based on a weed seed movement model that projects likely locations of the weed seeds given a location of one or more weed plants in the field that produced the weed seeds, wherein the weed seed movement model represents machine delay compensation and models a distance, relative to a surface of the field, between:
- when a weed plant that carried the weed seeds is cut by the agricultural harvesting machine, and
- the weed seeds are discharged on to the surface of the field by the agricultural harvesting machine;
- and
- generate a control signal associated with a pre-emergence weed seed treatment operation on the weed seeds, prior to emergence of the weed seeds, based on the weed seed area.
A method performed by an agricultural harvesting machine, the method comprising:
- operating crop processing functionality of the agricultural harvesting machine to engage crop in a field, perform a crop processing operation on the crop to obtain processed crop, and move the processed crop to a harvested crop repository;
- identifying a weed seed area indicating presence of weed seeds based on a weed seed movement model that projects likely locations of the weed seeds given a location of one or more weed plants in the field that produced the weed seeds, wherein the weed seed movement model represents machine delay compensation and models a distance, relative to a surface of the field, between:
- when a weed plant that carried the weed seeds is cut by the agricultural harvesting machine, and
- the weed seeds are discharged on to the surface of the field by the agricultural harvesting machine;
- and
- generating a control signal associated with a pre-emergence weed seed treatment operation based on the weed seed area.
An agricultural harvesting machine comprising:
- crop processing functionality configured to engage crop in a field, perform a crop processing operation on the crop to obtain processed crop, and move the processed crop to a harvested crop repository;
- and
- a control system configured to:
- identify a weed seed area indicating presence of weed seeds based on a weed seed movement model that projects likely locations of the weed seeds given a location of one or more weed plants in the field that produced the weed seeds, wherein the weed seed area is identified based on chaff spreader data received from a chaff spreader sensor on the agricultural harvesting machine, wherein the chaff spreader data represents chaff ejected from the agricultural harvesting machine during the crop processing operation;
- and
- generate a control signal associated with a pre-emergence weed seed treatment operation on the weed seeds, prior to emergence of the weed seeds, based on the weed seed area.
