Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system may determine a first real-world geo-spatial location of the treatment system. The system can receive captured images depicting real-world agricultural objects of a geographic scene. The system can associate captured images with the determined geo-spatial location of the treatment system. The treatment system can identify, from a group of mapped and indexed images, images having a second real-word geo-spatial location that is proximate with the first real-world geo-spatial location. The treatment system can compare at least a portion of the identified images with at least a portion of the captured images. The treatment system can determine a target object and emit a fluid projectile at the target object using a treatment device.

A method for the application of agricultural fluid to a field includes determining a location of each of a plurality of nozzles of an agricultural spraying machine. A flow rate for each of the nozzles is determined based on each respective nozzle's location in the field. A field map is used to determine a crop requirement and application restriction associated with a nozzle's location. The field map contains indications of crop requirements and application restrictions. The flow rate for a nozzle is determined by comparing the nozzle's location to the field map. A flow rate signal is transmitted to each of the nozzles based on its determined flow rate.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system uses a treatment unit for emitting a laser at agricultural objects. The treatment unit is configured with a treatment head assembly that includes a moveable treatment head with one or more laser emitting tips. A first and second motor assembly are operated by the treatment unit to control the movement of the treatment head. The first motor assembly includes a first motor rotatable in a first rotational axis. A first linkage assembly is connected to the first motor and the treatment head assembly. The first linkage assembly is rotatable by the first motor. The second linkage assembly is rotatable by the second motor.

Methods and systems for administering agrochemicals with an agricultural sprayer are provided. In a method a ground speed of the sprayer is measured. A current volumetric air flow produced by a fan of the sprayer is determined and compared with a required volumetric airflow. Settings of the fan (such as rotational speed and blade pitch settings) are adjusted if the current and required volumetric air flows differ The required volumetric air flow of the fan is determined using the measured ground speed, a configured plant height and width and sprayer air volume delivery curves at different fan settings.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The system uses a pump in combination with a fluid regulator to obtain and disperse fluid from the fluid tanks. The fluid regulator includes a fluid input port, a fluid output port and a fluid control valve. A first tube fluidly coupled from the fluid pump to the fluid input port. The system includes a moveable treatment head having one or more spraying tips, including a first spraying tip. A second tube is fluidly coupled from the fluid output port to the moveable treatment head. A system includes a controller configured to provide to the fluid regulator to open and close the fluid control valve to release an amount of the first fluid.

A method for classifying plants for agricultural purposes. The method includes: detecting a field section having plants using an optical detection unit inclined toward the field section to obtain image information having a rear image edge having an image width and a front image edge having a larger image width; classifying the plants in the image information into first and second plant classes using an algorithm to treat the plants of the second plant class with a liquid spray agent, in accordance with the classification. The step of classifying comprises a step of reclassifying, in which classified plants are reclassified from the second plant class to the first plant class using the algorithm if they extend in a rear image section of the image information defined by a defined image separation line from a lateral image edge of the image information maximally up to a defined reclassification boundary line.

A liquid distribution system for a crop sprayer includes a product tank configured to contain a liquid, a pump, and nozzles carried by a boom. The product tank has a fluid inlet, and at least one water quality sensor is configured to detect a water quality property of liquid entering the product tank through the fluid inlet. Methods of operating a crop sprayer include measuring a first water quality property of fresh water entering a product tank, measuring a second water quality property of rinsate formed from the fresh water within the product tank, removing the rinsate from the product tank, and if a difference between the second water quality property and the first water quality property is greater than a preselected threshold, forming a second rinsate in the product tank.

A fertigation apparatus that can be installed on a water supply line of an irrigation system. The fertigation apparatus includes a body that has an open top, an inlet near the open top, and an outlet near a bottom of the body, a cap configured to close the open top, and a mesh basket encased within the body, the mesh basket can receive one or more tablets of fertilizer and pest or weed control. A diverter can selectively switch the water between the direct water supply line or through the apparatus.

A spray apparatus for a vehicle includes a processing unit with at least one image of an environment. The processing unit analyzes the at least one image to activate at least one chemical spray unit mounted on the vehicle. Air is blown by at least one air blower mounted on the vehicle into a first downward directed air flow with respect to the vehicle.
