A liquid applicator implement includes a vehicle supporting a boom which is vertically adjustable with respect to the vehicle. The boom supports a plurality of drop assemblies laterally spaced along the boom, each of the plurality of drop assemblies is in communication with a liquid product source. At least one height sensor assembly is attached to one of the plurality of drop assemblies. The at least one height sensor generates signals indicative of a distance between the one drop assembly and a ground surface as the vehicle advances in a direction of travel. At least one adjustment mechanism coupled to the boom is responsive to the signals generated by the at least one height sensor assembly for vertically adjusting the boom as said vehicle advances in the direction of travel.

A liquid dispensing apparatus for applying liquid products to row crops. The liquid dispensing apparatus includes a plurality of drop assemblies supported by and laterally spaced along a boom structure. Each of the drop assemblies includes dribble hoses for dribbling a liquid product onto the soil in a rhizosphere of adjacent crop rows. The drop assemblies may include a spray assembly for spraying the row crops. The dribble hoses may be supported by a base unit with positionable support brackets.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a nozzle includes a fluid inlet, a fluid outlet, and a rotatable member to rotate over the fluid outlet to selectively expose the fluid outlet to at least one opening to provide fluid flow from the fluid outlet through the opening. Upon the rotatable member rotating over the fluid outlet, a different number of openings is in fluid communication with the fluid outlet.

Disclosed is an agricultural air injection apparatus including: a compressor for compressing air; an air tank which has a pressure gauge and a safety valve for presenting overpressure and stores compressed air of high pressure in a set pressure condition; a decompression valve for decompressing air pressure discharged from the air tank; a sprayer for spraying water in a particle state in order to make vapor contained in the supplied air; a distributor which uniformly distributes the decompressed air to a plurality of flow paths and has a control valve to open and close the flow paths; an air supply pipe which is buried in the soil where crops to be cultivated will be planted and has pores for supplying air passing through the distributor; and a controller which is connected to the compressor, the pressure gauge of the tank and the control valve of the distributor to control supply of the compressed air.

A fluid application system includes a manifold defining an internal passageway, a plurality of nozzles connected in fluid communication with the internal passageway, a plurality of electrically actuated valves for controlling fluid flow through the plurality of nozzles, where each valve of the plurality of electrically actuated valves is connected in fluid communication between the internal passageway and a corresponding one of the plurality of nozzles, and a pressure dampener connected to the manifold and configured to dampen fluctuations in fluid pressure within the internal passageway.

An autonomous vehicle platform system and method configured to perform various in-season management tasks, including selectively applying fertilizer, mapping growth zones and seeding cover crop within an agricultural field, while self-navigating between rows of planted crops and beneath the canopy of the planted crops on the uneven terrain of an agricultural field, allowing for an ideal in-season application of fertilizer to occur once the planted crop is well established and growing rapidly, in an effort to limit the loss of fertilizer.

A spraying system for spraying a fluid includes a nozzle assembly configured to spray the fluid in response to receiving a control signal, a sensor configured to transmit a detection signal upon detection of a target, and a user interface configured to receive input from an operator. The spraying system further includes a control system communicatively coupled to the sensor to receive the detection signal from the sensor, the control system configured to transmit the control signal to the nozzle assembly at least in part in response to reception of the detection signal, the control system further configured to determine a fluid band length and an offset distance of the fluid band length from the target based at least in part on information input by the operator to the user interface. The user interface displays a graphic representation of the fluid band length and the offset distance relative to the target.

An opener attachment for an agricultural row unit including a frame, an arm pivotally coupled to the frame, an opener disc coupled to the arm and configured to excavate a trench into soil, and a gauge wheel coupled to the arm and configured to block movement of the opener disc into the soil to control a depth of the trench. The opener attachment also includes a mechanical stop coupled to the frame and configured to block the gauge wheel and the opener disc moving toward the soil. In addition, the opener attachment includes an air bag configured to urge the gauge wheel and the opener disc toward the soil.

Locations of seeds in a field can be identified using event-based processing or frequency-based processing. A material is applied to the field, based upon the seed locations.

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 fluid to plants in rows in a field includes at least one applicator arm that is actuated by an actuator to move the applicator arm from a position in the row between plants to a position adjacent to the plant.
