A coulter assembly for collecting soil samples from an agricultural field in one embodiment comprises an annular collection blade configured for penetrating soil to capture a sample, an annular cam ring configured for stationary mounting to a frame of an agricultural vehicle and comprising a cam track, a blade hub coupled to the blade for rotatably supporting the annular collection blade from the annular cam ring, and a movable sample collector mounted to the annular collection blade. The moveable sample collector is configured and operable for extracting a soil sample as the annular collection blade is rotated through the soil. The moveable sample collector in one embodiment comprises a piston mechanism including a cylinder and rod movably disposed therein which actuated by the annular cam ring to alternatingly open and close a collection end of the cylinder as the annular collection blade rotates through the soil.

A system having a boom; a plurality of cameras attached to the boom; and a plurality of lenses on each camera; wherein not all lenses have a same field of view.

An agricultural method for preventing roll-back of an agricultural vehicle may include receiving a roll-back prevention input from a speed setting device indicative of a command to increase the transmission speed of the hydrostatic transmission while a service brake of the agricultural vehicle is engaged. Further, the method may include adjusting a speed mapping for the speed setting device from a predetermined speed mapping to a roll-back speed mapping in response to the roll-back prevention input, with the roll-back speed mapping being associated with a reduced speed range. Additionally, the method may include determining a transmission control command associated with a current position of the speed setting device based on the roll-back speed mapping and controlling an operation of the hydrostatic transmission to adjust the transmission speed based at least in part on the transmission control command.

An automatic fertilizing apparatus connected in series with a sprinkle watering system. The apparatus includes a liquid fertilizer container having an inlet and an outlet, and a venturi tube configured to sealably fit into the inlet and outlet of the container. The fertilizing apparatus includes a venturi tube that can sealably fit into the inlet port and the outlet port. Water pumped into the venturi tube can produce a partial vacuum that allows the liquid fertilizer in the container to be drawn into the venturi tube through a slot in the venturi tube. The liquid fertilizer can mix with the water stream in the venturi tube and the mixture of water and liquid fertilizer can be dispensed through a sprinkler head of the sprinkle watering system.

On a user interface presented on a display screen, an alteration point marker is rendered on a circular shape representing a center pivot irrigation system. The alteration point marker is aligned with an input point specified by user input. A fine position control may also be rendered on the display screen. The fine position control may comprise a first icon and a second icon, wherein the first icon is for repositioning the alteration point marker in a first circular direction, and wherein the second icon is for rotating the alteration point marker in the second circular direction.

A farming machine includes one or more image sensors for capturing an image as the farming machine moves through the field. A control system accesses an image captured by the one or more sensors and identifies a distance value associated with each pixel of the image. The distance value corresponds to a distance between a point and an object that the pixel represents. The control system classifies pixels in the image as crop, plant, ground, etc. based on depth information in in the pixels. The control system generates a labelled point cloud using the labels and depth information, and identifies features about the crops, plants, ground, etc. in the point cloud. The control system generates treatment actions based on any of the depth information, visual information, point cloud, and feature values. The control system actuates a treatment mechanism based on the classified pixels.

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.

Systems, devices, and methods for detecting agrochemicals in environments associated with agricultural equipment are described. Certain agrochemicals that are formulated for being detected using the systems, devices, and methods disclosed herein are also described. The devices, systems, and methods disclosed herein are generally configured to use spectral characteristics to detect agrochemicals in an environment associated with agricultural equipment. The spectral characteristics can be analyzed in various ways to provide different types of information about the agrochemicals and/or the environment.

The present invention provides a variable rate precision fertilizer applicator, comprising a connecting plate, a fertilizer bin and a fertilization mechanism. A plurality of connecting belts are fixed on the connecting plate; the connecting plate is connected with a fertilization unmanned aerial vehicle (UAV) through the connecting belts; a connecting column is fixed on a bottom surface of the connecting plate, and the connecting plate is fixedly connected with the fertilizer bin through the connecting column; a storage bin is separated into a solid bin and a liquid bin through a partition plate; a release bin is arranged on one side of the storage bin; the spiral feeding cylinder is installed in the solid bin; a liquid pump is installed in the liquid bin; the discharge port is installed in the release bin; the fertilization mechanism is installed at the bottom side of the fertilizer bin.

A system for applying an agricultural product includes at least one control valve. For instance, the control valve has a moveable valve operator. One or more sensors monitor one or more control valve characteristics. A valve controller is configured to determine the control valve is in one or more of a primed state or an unprimed state based on a comparison of the one or more control valve characteristics to a primed valve characteristic threshold.
