In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

A method includes obtaining, by the treatment system configured to implement a machine learning (ML) algorithm, one or more images of a region of an agricultural environment near the treatment system, wherein the one or more images are captured from the region of a real-world where agricultural target objects are expected to be present, determining one or more parameters for use with the ML algorithm, wherein at least one of the one or more parameters is based on one or more ML models related to identification of an agricultural object, determining a real-world target in the one or more images using the ML algorithm, wherein the ML algorithm is at least partly implemented using the one or more processors of the treatment system, and applying a treatment to the target by selectively activating the treatment mechanism based on a result of the determining the target.

Application units provide placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

A boom for an agricultural crop sprayer has an elongate triangular box arrangement that is load bearing and serves to carry liquid dispensing devices for the application of crop protection products. The box arrangement includes three elongate plates each formed preferably from a carbon fiber material. The plates may be secured together by bolts or rivets by three connecting members that each present elongate edges of the box arrangement.

An agricultural vehicle is moveable across a surface. The agricultural vehicle includes a chassis, a traction member coupled to the chassis with the traction member configured to engage the surface and move the chassis relative to the surface, a holding tank coupled to the chassis with the holding tank configured to support agricultural matter, a support boom coupled to the chassis, and a plurality of applicator assemblies. Each applicator assembly of the plurality of applicator assemblies includes a resilient body coupled to the support boom, a foot coupled to the body with the foot configured to be biased into engagement with the surface via the resiliency of the body, and a nozzle. The nozzle is in communication with the holding tank and configured to dispense the agricultural matter.

A system for actuating a boom assembly of an agricultural sprayer, the system having a frame, a boom assembly supported relative to the frame, and a linkage assembly configured to couple the boom assembly to the frame. The linkage assembly includes a support arm pivotably coupled between the frame and the boom assembly, a lift actuator pivotably coupled between the frame and the support arm and configured to raise and lower the boom assembly in a vertical direction, and a nit actuator pivotably coupled between the frame and the boom assembly and configured to adjust a tilt angle of the boom assembly relative to the vertical direction. The system further includes a controller configured to selectively actuate the tilt actuator to adjust the tilt angle of the boom assembly to an operational tilt angle.

A treatment mechanism for dispensing treatment fluid onto one or more plants in a field is described. The treatment mechanism includes a valve for regulating the dispensing of treatment fluid and a nozzle holder comprising a plurality of nozzles. Each nozzle is configured to dispense treatment fluid and to couple to the valve. The treatment mechanism further includes a control system configured to receive a plant treatment instruction for treating the plants. The plant treatment instruction includes a treatment position for the nozzle holder. The control system is further configured to determine a current position of the nozzle holder and adjust the current position of the nozzle holder to the treatment position for the nozzle holder. The control system is further configured to actuate the treatment mechanism such that the plants are treated via a nozzle of the plurality of nozzles.

A method for performing spraying operations includes controlling a speed system to move an agricultural sprayer across a field at a speed equal to or below a ground speed limit of the agricultural sprayer, receiving data from a field condition sensor indicative of one or more field conditions within the field, and controlling the operation of a plurality of nozzle assemblies provided in association with a boom of the agricultural sprayer to perform a spraying operation based at least in part on the data received from the field condition sensor. The method additionally includes monitoring an operating parameter indicative of a travel speed of each of the plurality of nozzle assemblies, and automatically adjusting an operation of the agricultural sprayer in response to the determination that the travel speed of at least one of the plurality of nozzle assemblies exceeds or is likely to exceed the ground speed limit.
