An agricultural method includes providing a positive air pressure chamber to prevent outside contaminants from entering the chamber; growing crops in a plurality of cells in the chamber, each cell having multi-grow benches or levels, each cell further having connectors to vertical hoists for vertical movements in the chamber; maintaining pre-set temperature, humidity, carbon dioxide, watering and lighting levels to achieve predetermined plant growth; using motorized transport rails to deliver benches for operations including seeding, harvesting, grow media recovery, and bench wash; dispensing seeds in the cell with a mechanical seeder coupled to the transport rails; growing the crops with computer controlled nutrients, light and air level; and harvesting the crops and delivering the harvested crop at a selected outlet of the chamber.

The invention relates to a device for moistening and/or fertilizing plants (1), comprising a movable spray lance (3) with at least one spray nozzle (4) arranged on the spray lance (3), wherein a preferably linear guide rail (2) is provided, wherein the spray lance (3) is movably guided in the guide rail (2) in a trajectory extending parallel to the guide rail (2) and extends substantially normal to this trajectory, and wherein a drive, preferably a linear drive (11), is arranged for moving the spray lance in the area of the guide rail (2). The invention further relates to a system for cultivating plants without a substrate, comprising the device according to the invention.

An agricultural sprayer system is provided herein that can include a boom assembly having a frame and a boom arm operably coupled with the frame at one end portion thereof. Outer and inner nozzle assemblies can each be supported by the boom arm. The inner nozzle assembly is inboard of the outer nozzle assembly. A sensor can be operably coupled with the boom assembly and configured to capture data associated with the boom arm. A computing system can be communicatively coupled to the sensor. The computing system can be configured to calculate a boom arm movement from a default axis based on the data from the sensor and regulate the outer and inner nozzle assemblies at differing flow rates when the movement exceeds a predefined range.

A method of automatically selecting a nozzle set from a plurality of nozzle sets on an agricultural spraying machine is provided. The method includes receiving an application rate setpoint, and for each nozzle set an upper pressure limit, a lower pressure limit, a nozzle reference flow, and a nozzle reference pressure. A speed range is calculated for each nozzle set, wherein each speed range comprises a lower speed limit and an upper speed limit. One of the nozzle sets is selected based upon a sensed forward speed and the calculated speed ranges.

Spraying boom support for agricultural sprayers, whether trailed, self-propelled and/or airborne, which includes identical articulated arms arranged on either side of the sprayer. Said arms are extended transversely to the direction of advance of the sprayer, and are coupled in an articulated manner to a central support section of the chassis of said sprayer. Each articulated arm is comprised of bar sections formed by a composite material consisting of a reinforcing agent selected from carbon fiber, fiberglass, aramid fiber, boron fiber or a combination thereof, and a matrix of epoxy, vinyl ester, phenolic, polyester resins or thermoplastic material. At its ends, the bar sections have metal nodes that make up the joints and links, also fulfilling the role of taking the concentrated loads of them and distribute them in the bar sections of composite material. In this way areas of great thickness of composite material are avoided and the advantages of each material are exploited resulting in an economical, efficient, lightweight, low maintenance and easily repairable design.

An agricultural applicator, that applies material to an agricultural field, includes an on-board, real-time image sensor that senses targets for the material to be applied. A controller controls applicators, such as nozzles or other applicators, to apply the material to the sensed targets

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.

An agricultural potassium-fertigation method for emitter-irrigation potassium fertigation feeds a potassium-nutrient feedstock comprised of potassium formate and water to an active emitter-irrigation system continuously, or substantially continuously, at low levels, during the entire time, or substantially the entire time, that irrigation water is sufficiently flowing through the irrigation system during a prolonged term.

The present invention relates to a method for producing water having a stable high nitrate content, an organic fertilizer comprising the water having a stable high nitrate content thus produced, and use of the water having a stable high nitrate content in a method for the organic cultivating of a plant in a substrate. The present invention further relates to a continuous flow system for supplying plants with the water having a stable high nitrate content.

Described herein are systems and devices for controlling and monitoring liquid applications of agricultural fields. In one embodiment, a flow device for controlling flow during an agricultural operation includes an offset ball valve having multiple openings that rotate in position to control flow of a liquid through the offset ball valve to an outlet passage. The flow device also includes a first passage that provides a first flow path from an inlet to at least one opening of the offset ball valve and second passage that provides a second flow path from the inlet to at least one opening of the offset ball valve.
