A system for detecting and identifying plant species in an agricultural field that allows to act on them, which comprises at least one camera that includes a lens, a bandpass filter and an image sensor; a GPS unit; and at least one data processing unit comprising data storage means and in data communication with the at least one camera and with the GPS unit, wherein each data processing unit comprises a system for calibrating the cameras, where the cameras capture and send images to the data processing unit, where each data processing unit is configured to autonomously detect and identify plant species, discriminating between crops, weeds and soil, based on the images that it receives and make decisions as detected and identified, and where each data processing unit geolocates the detected plant species. A method that uses the plant species detection and identification system of the present invention to detect and identify plant species in an agricultural field.

The invention relates to a spray unit comprising an axle (10), a disc (20), a liquid applicator (40) and a spray direction assembly (50). The disc is configured to spin about the axle centred on the centre of the disc. The liquid applicator is configured to apply liquid to a surface of the disc. The spray direction assembly partially surrounds the disc. The inner surface of the spray direction assembly is configured to modify the trajectory of all liquid that leaves the outer edge of the disc.

A method includes receiving, by the treatment system, during operation in an agricultural environment, one or more images comprising one or more agricultural objects in the agricultural environment, identifying, in real-time, one or more objects of interest from the one or more agricultural objects by analyzing the one or more images, wherein the analyzing results in a first object being identified as belonging to one or more target objects and a second object being identified as not belonging to the one or more target objects, logging one or more results of the identification of each of the one or more objects of interest and a corresponding treatment decision; and activating the treatment mechanism to treat the one or more target objects.

The invention relates to an agricultural apparatus (1) for spreading material, such as fertilizers, plant protection products, or seed, comprising a distributor linkage (10) which can be folded on both sides, comprising a central part (11), where the central part (11 ) is connected in a rotationally fixed manner to the agricultural apparatus (2 ), two intermediate frames (12a,b) connected to the central part (11) in particular by joints, two lateral booms (13a,b) connected to the respective intermediate frames (12a,b), and a damping assembly (19) for damping motions of the first boom (13a) and the second boom (13b) in the direction of travel of the agricultural apparatus (1), where the damping assembly connects the intermediate frames (12a,b) to one another in particular independently of the central part (11), or where the damping assembly (19) connects the respective intermediate frames (13a,b) to the central part (11).

A system for an agricultural operation includes a first vehicle equipped with an imaging sensor configured to capture image data associated within a field. A computing system is communicatively coupled with the imaging sensor. The computing system is configured to receive the image data associated with the field, identify one or more objects within the image data as a target, identify one or more objects within the image data as a landmark, determine a location of the target relative to the landmark, and generate a control command for a second vehicle. The control command includes the location of the target relative to the landmark within the field.

A system for an agricultural vehicle can include a nozzle assembly positioned along a boom assembly. A position sensor can be associated with the boom assembly. A field sensor can be associated with the nozzle assembly. A computing system can be operably coupled with the nozzle assembly, the position sensor, and the field sensor. The computing system can be configured to detect a target within a field based on data from the field sensor, determine a boom deflection model based on data from the position sensor, and activate the nozzle assembly to apply an agricultural product to the target at a first flow rate based on the boom deflection model. The first flow rate is varied from a nominal flow rate when the boom assembly is deflected.
