An irrigation system is provided for irrigating a field divided into irrigation zones. The irrigation zones are arranged in columns extending alongside each other. The system has irrigation strips and a control head at an upstream end of each irrigation strip. Each irrigation strip provides irrigation substances to a column of zones. All control heads are located alongside a boundary of the field outside of the irrigation zones.

A fluid dispersion nozzle and system for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the fluid dispersion nozzle receives pressurized and fluid from fluid dispersion machinery, aerosolizes the fluid into near-monodispersed droplets, and distributes the aerosolized, near-monodispersed droplets evenly over long distances. The nozzle is an adjustable, dual-contour, supersonic nozzle that includes a main adjustable contour, an auxiliary contour, an axial fluid injector, a resonator, and a plunger.

A soil conditioner spreader and an operation method thereof are provided. The soil conditioner spreader includes a spreader body, a ridger, a solid tank, two spiral drills, a rotary tillage wheel and a mulching device, where the spreader body is provided with a hopper in a front part. The hopper stores a conditioner. The solid tank is arranged above the spiral drills. The spreader body is connected to the solid tank through a feeding track. The ridger, the spiral rills, the rotary tillage wheel and the mulching device are successively arranged at the bottom of the spreader body from the rear to the front. The ridger ridges first, and then the spiral drills perform deep plowing, rotary tillage and scarification and apply the conditioner to a ridge. The rotary tillage wheel performs rotary tillage, and a nozzle sprays a nutrient solution or an herbicide/insecticide. Finally, the mulching device mulches.

The present invention provides a molluscicide application apparatus and process that disperses the molluscicide below the water's surface in a manner that minimizes air entrainment and ensures that the molluscicide solution settles at the targeted floor of the body of water, such as a river or lake bed where driessenid mussels are concentrated, and do not rise to the water's surface or disperse. The present invention also maintains a desired viscosity level, for example, 180 centistokes, at typical freshwater temperatures varying from 15 C. to 25 C. by adjusting the flow rate and/or nozzle orifice area of the molluscicide application.

A spray nozzle system includes a nozzle body and an adaptor coupled to the nozzle body. The adaptor has a first region and a second region angled at a non-zero angle relative to the first region. The spray nozzle system also includes a nozzle cap coupled to the second region of the adaptor. The nozzle cap includes a nozzle outlet to spray a liquid.

A system for dispensing multiple low rate agricultural products that includes a multiple low rate agricultural (MLRA) product application device configured to cooperate with a planting equipment monitor assembly positioned to sense a seed being discharged from high speed planting equipment. Each MLRA product application device comprises a common housing for a number of low rate agricultural product input assemblies.

The invention provides a system for equalizing airflow in lines delivering product-conveying air to boom sections of an agricultural machine by controlling valves, such as electronically, in each air distribution line to induce additional pressure drops in lines which would cause imbalance in the system. Such valves can include, but are not limited to: ball valves, butterfly valves, gate valves, globe valves, diaphragm valves, pinch valves and/or plug valves. With the proposed system, the lines of least pressure drop can be induced with additional pressure drop by particular valves in order to bring the lines back to a balanced state.

A computing system is providing for managing a fleet of spraying vehicles by selecting one or more field zones to be sprayed by a fleet of spraying vehicles. The system reviews spraying requirements including material and quantity to be sprayed and reviews spraying vehicle parameters for each spraying vehicle in of the fleet. The system then calculates a travel plan for each spraying vehicle such that the selected field zones can be sprayed accordingly without spraying areas outside the selected field zones. Once in operation, the system verifies travel plan execution of each spraying vehicle and adjusts one or more travel plans in case of vehicle malfunctions, unexpected weather conditions, and unexpected field obstacles.

Various embodiments of methods, systems, and computer program products described herein are directed to a treatment system. An example method includes identifying a type of a first target agricultural object, based on the identified type of the first target agricultural object, determining a first spray profile for treating the first target agricultural object, sending instructions of a first treatment parameter to a treatment unit, and based on the first spray profile, activating the treatment unit to emit a first fluid at the first target agricultural object, wherein the first fluid regulator is moved to an opened position for an amount of time such that the first fluid is emitted, via the first spraying tip, as a first fluid projectile at the first target agricultural object for a first spray duration.
