Autonomous soil sampling and herbicide application

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

• detect a weed at a first location of an autonomous applicator system within a field at a first time;
• identify one or more characteristics of the weed and/or environment;
• determine an herbicide application strategy for the weed based on the one or more characteristics;
• activate a solenoid within the applicator system to enable a flow of herbicide via an applicator nozzle to treat the weed in accordance with the herbicide application strategy;
• navigate the autonomous applicator system back to the first location from another location at a second time after treating the weed in accordance with the herbicide application strategy;
• detect a condition of the weed at the first location at the second time;
• and
• update the herbicide application strategy for the one or more characteristics in response to the condition of the weed at the first location at the second time, wherein the updating causes the autonomous applicator system to change how herbicide is subsequently applied to weeds having the one or more characteristics.

An autonomous herbicide applicator system comprising:

• an applicator nozzle;
• a solenoid within the applicator system to enable a flow of herbicide via the applicator nozzle;
• a memory device;
• and
• a processing device, operatively coupled with the memory device, to:
• detect a weed at a first location of an autonomous applicator system within a field at a first time;
• identify one or more characteristics of the weed and/or environment;
• determine an herbicide application strategy for the weed based on the one or more characteristics;
• activate the solenoid within the applicator system to enable a flow of herbicide via the applicator nozzle to treat the weed in accordance with the herbicide application strategy;
• navigate the autonomous applicator system back to the first location from another location at a second time after treating the weed in accordance with the herbicide application strategy;
• detect a condition of the weed at the first location at the second time;
• and
• update the herbicide application strategy for the one or more characteristics in response to the condition of the weed at the first location at the second time, wherein the updating causes the autonomous applicator system to change how herbicide is subsequently applied to weeds having the one or more characteristics.
