A trough is cut in the ground surface by a rotating member. The rotating member displaces soil upward with respect to the ground surface and rearwardly with respect to a direction of travel of the rotating member. While the soil is in the air, slurry is deposited into the trough. The soil is then redirected downward to the trough to cover the slurry with the soil.

A modular system includes a hub and a set of modules removably coupled to the hub. The modules are physically coupled to the frame relative to each other so that each module can operate with respect to a different row of a field. An individual module includes a sensor for capturing field measurement data of individual plants along a row as the modular system moves through the geographic region. An individual module further includes a treatment mechanism for applying a treatment to the individual plants of the row based on the field measurement data before the modular system passes by the individual plants. An individual module further includes a computing device that determines the treatment based on the field measurement data and communicates data to the hub. The hub is communicatively coupled to the modules, so that it may exchange data between the modules and with a remote computing system.

A seeding apparatus includes a frame supported on ground-engaging wheels, an opening device for creating a trench, a seed reservoir, and seed dispensing apparatus configured to deposit seed in the trench. The opening device is mounted to the frame by a four-bar linkage having first and second link arms. Each of the first and second link arms is pivotably connected to the frame by respective first and second pivot joints, and to the opening device by respective third and fourth pivot joints disposed forwardly of the first and second pivot joints. The opening device is ‘pushed’ through the soil via the four-bar linkage.

A method for plantation treatment of a plantation field, the method comprising: determining (S10) an application rate decision logic (10) based on offline field data (Doff) relating to expected conditions on the plantation field (300); taking (S20) an image (20) of a plantation of a plantation field (300); recognizing (S30) objects (30) on the taken image (20); determining (S40) an application rate based on the determined application rate decision logic (10) and the recognized objects (30); and determining (S50) a control signal (S) for controlling a treatment arrangement (50) of a treatment device (200) based on the determined application rate.

Provided is a method and device for adjusting a broadcast dosage, an unmanned aerial vehicle and a storage medium. Applied to the unmanned aerial vehicle for broadcast through a material taking device driven by an electric motor, the method particularly includes: receiving a calibration instruction including a calibration rotation speed and calibration duration, controlling the electric motor to run at the calibration rotation speed within the calibration duration to discharge a material to be broadcast; acquiring a flight parameter and an actual discharge amount of the material to be broadcast discharged by the material taking device within the calibration duration; determining an adjustment coefficient between a flight speed and a rotation speed of the electric motor according to the flight parameter and the actual discharge amount; and adjusting the rotation speed of the electric motor to adjust the broadcast dosage according to the adjustment coefficient.

An apparatus for clearing trash from a soil surface, the apparatus being configured to be mounted on a towable frame support and driven across the soil surface in a direction of travel (“D”), the apparatus comprising: a bearing housing; and a soil-engaging member rotatably mounted to the support, wherein the soil-engaging member is oriented to rotate about an axis (“A”) tilted from a perpendicular to the soil surface (“B”) by an acute angle (Φ1) towards one lateral side relative to the direction of travel (“D”), whereby contact between the soil-engaging member and the soil surface induces rotation of the soil-engaging member around the axis (“A”).

Device for shaping the profile of a furrow, sensing soil properties and dosing fluids in the soil of an agricultural field, includes a body comprising an upper portion and lower portion defining a right lateral face and a left lateral face that are laterally opposite, a front face and a rear face that are longitudinally opposite, and an upper face and lower face that are vertically opposite, wherein the laterally opposite faces at the lower portion of the body are angled relative to a vertical direction forming a V-shaped profile cross section for V-shaping furrows; damping and biasing means linked to the upper face of the body; a fluid dosing conduit including an inlet and an outlet, and being longitudinally arranged within the body; sensing means on a face of the body for measuring soil properties; and a sensing unit for commanding the sensing means and receiving information thereof.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. 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.

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.
