Described herein are implements and application units for 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.

Apparatus, system, and method are provided herein for causing and controlling the injection of fertilizer into an irrigation of an irrigation system. The fertigation system comprises a fertigation supply unit including at least one storage container containing at least one of a fertilizer component, a herbicide, and an insecticide coupled to a irrigation of the irrigation system. A fertigation control unit is coupled to the fertigation supply unit. The fertigation control unit is configured to cause the fertigation supply unit to inject at least some of the fertilizer component, herbicide, and/or insecticide into the irrigation. The fertigation control unit can cause the fertigation supply unit to inject the fertilizer component, herbicide, and/or insecticide in response to at least air temperature data and/or soil temperature data received from a sensor unit, or in response to user input at the fertigation control unit.

An apparatus for use in establishing or re-establishing plant growth over a land area. The apparatus includes a supply of a growing medium and an arrangement including at least one delivery outlet for delivering the growing medium at spaced intervals from a height onto a soil surface of the land area. The growing medium contains seeds or is delivered in tandem with and on top of seeds deposited on the soil surface or deposited onto or adjacent to seeds or seedlings already deposited on the soil surface.

An amphibious pumping vehicle has a floatable vehicle body, a ground engaging propulsion structure, a fluid pump, a plurality of fluid nozzles comprising a first fluid nozzle connected by a fluid conduit to the fluid pump and at least one second fluid nozzle connected to the fluid conduit, a valve structure in the fluid conduit, the plurality of fluid nozzles and the valve structure co-operating to provide directional control and motive power for the vehicle when floating, and a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump.

A treatment system for spraying treatment fluid onto plants in a field is described. The treatment system includes a highly configurable treatment mechanism including an array of nozzles and valve assemblies coupled into manifolds, and manifold assemblies. The manifolds of the manifold assemblies can be oriented in an open state or a nested state, the open state with no overlap between nozzles of adjacent manifolds and the nested state with overlap between nozzles of adjacent manifolds. The manifolds can have multiple configurations, examples of which include a tube manifold and an offset manifold. The nozzles of the system can have multiple configurations, examples of which include a tri-spray nozzle, a bar nozzle, a fan nozzle, and a deflected fan nozzle. The system can be controlled by a system controller which detects plant material and instructs a nozzle or combination of nozzles to spray treatment fluid.

An agricultural implement includes a storage tank, a pump positioned below a bottom portion of the storage tank, and a control system disposed above the bottom portion of the storage tank. The storage tank is configured to hold a flowable agricultural product. The pump is configured to direct the flowable agricultural product out of the storage tank. The one or more controls are configured to control application of the flowable agricultural product.

Land cultivating systems and methods utilizing high-pressure fluid jet cutting techniques are disclosed. An example system includes a mobile unit, a traveler arrangement operably coupled to the mobile unit to ride on the surface of stubble residues as the mobile unit moves across land to be cultivated, and a fluid jet cutting head supported by the traveler arrangement. The cutting head is configured to selectively discharge a high-pressure fluid jet to make a cut through the stubble residues and underlying soil as the mobile unit moves across the land. A soil opening device is provided to form a furrow in the ground in line with the cut made by the high-pressure fluid jet, and a liquid injector nozzle is provided to discharge fertilizer or other chemical(s) into the soil.

A system for changing pressure in one or more tires of a self-propelled agricultural machine according to a load differential determined using load sensors on opposing locations of the machine. A load differential may be caused by a disproportionate distribution of forces and/or weight on the machine. Load sensors proximal to the tires may allow determining corresponding loads on the tires and, in turn, the load differential. As a result, tires experiencing greater loads may be inflated, whereas tires experiencing lesser loads may be deflated. In addition, a Human Machine Interface (HMI) may be provided in the operator cab to allow an operator to have further control over tire inflation on the fly while operating the machine.
