A spray device for deploying liquids, in particular for agricultural purposes. The spray device includes at least one spray nozzle for spraying the liquid and includes at least one mixing unit, which encompasses at least one mixing chamber. The mixing chamber includes at least one first inlet for a carrier liquid, at least one second inlet for an active agent liquid, and at least one outlet. The mixing unit encompasses at least one control member for setting a mixing ratio of carrier liquid and active agent liquid. The control member is rotatably mounted in the mixing chamber, a through-flow cross-section of at least the first inlet and/or the second inlet being set depending on the rotation position of the control member.

A method for monitoring and/or modifying an active agent concentration in a spray liquid of a spray device including a plurality of spray nozzle units for deploying the spray liquid for agricultural purposes. The method includes receiving one property signal each including a piece of property information of the spray liquid detected with the aid of a sensor unit of the spray device in a through-flow area of one each of the spray nozzle units, an active agent concentration in the spray liquid being ascertainable using the piece of property information; and outputting an information signal to a display unit and/or a control signal to an intermixing unit and/or a delivery unit of the spray device as a function of the received piece of property information of the spray liquid and/or of an active agent concentration in the spray liquid ascertained using the piece of property information.

A device for dispensing a spraying agent, e.g., a plant protection agent, includes a mixing unit for mixing two active agents to form a spraying agent, at least one of the active agents being suppliable to the mixing unit under pressure via a throttle unit, the throttle unit including a feed channel and a discharge channel that are fluidically connectable to each other via at least one throttle channel depending on a position of a throttle element of the throttle unit that is movably situated relative to the feed channel the discharge channel for setting a flow rate of the at least one active agent to be supplied to the mixing unit, the at least one throttle channel being situated at the throttle element and having a fixed channel cross section for keeping the through-flowing flow rate of the at least one active agent constant.

A system and method that automatically monitors product use, such as the type and amount of agricultural and/or horticultural product stored in and dispensed from a cartridge over time and/or by geographic location. Monitored data are stored in memory such as a tag on the cartridge and may be transmitted to a server for storage, aggregation, and analysis. The cartridge may be authenticated before being authorized for use for the benefit of a current user in dispensing the product. The cartridge may be refilled after confirmation of authorization codes on the cartridge and refilling equipment tags. The cartridge may be calibrated automatically based on the bulk density or other parameter of the product in the cartridge. Data may be aggregated from a plurality of cartridges automatically. As-applied data from individual cartridges may be used to verify, independent of operator input, treated area coverage and product application rate.

The present invention provides an agricultural product delivery system in which a support structure or skid well is configured to rigidly support a primary product storage tank that is manufactured from a non-metallic material such as polyethylene or plastic. The product storage tank can have a capacity of at least 500 gallons, and preferably 1000 gallons, and the support structure can include multiple support ribs spaced along sides of the tank for providing rigid support for the tank and preventing deformation when filled with liquid. In addition, the product storage tank can include one or more contours or cavities for accommodating smaller chemical injection tanks positioned therein. Such chemical injection tanks can also be rigidly supported by the support structure. A spray system can mix liquid from the product storage tank and chemical from a chemical injection tank for spraying a field.

The inventive subject matter provides a method for the incorporation of colored photoluminescent materials to be sprayed on to plants and soils. The incorporation of colored photoluminescent materials assists the spray operator through the use of black lights allowing for more precise low right or nighttime spray and seeding operations. More specifically, this invention relates to a colored photoluminescent adjuvant to be applied to targeted crops, plants and seeds to assist in the low light or nighttime application of bioactive agents, such as chemicals and pesticides. The colored photoluminescent adjuvant can be applied as a solution or a foam.

A method for applying a spray agent is described, in particular, a plant protection product, onto an agricultural area to be treated with the aid of a spraying device, including a spray agent tank and at least one fluidic connecting line from the spray agent tank to a nozzle. The method includes the following steps: selectively applying the spray agent onto an initial section of the agricultural area, and subsequently extensively applying a residual amount of spray agent onto a residual section of the agricultural area using a predefined application amount in such a way that, upon completion of the treatment of the agricultural area, essentially the entire residual amount of spray agent has been applied.

Methods and apparatus for adjusting a delivery, distribution, emission, or spray of an adaptable material include contacting the adaptable material with a compatibly-selected kinetic energy fluid. The contact provides a motive force to move the adaptable material to or from an outlet of a spray fixture. The spray fixture is adjustable to emit various forms of drops, mists, extrusions, emulsions, or fibers. The adjusting is based on characteristics of a feedstock material, the adaptable material, the compatibly-selected kinetic energy fluid, or combinations thereof.

A system for dispensing crop input products from multiple meters per crop row, including: a) a georeferencing module configured to receive and process georeferenced location information; b) a prescriptive control module configured to receive the processed georeferenced location information from the georeferencing module and utilize the georeferenced location information to generate specific prescriptive rate information for individual meters in the field; and, c) a meter controller module operatively connected to the prescriptive control module. The meter controller module is configured to utilize the specific prescriptive rate information to individually control multiple meters per crop row, to simultaneously dispense crop input products at specific prescriptive rates at georeferenced locations throughout the field.

An irrigation system broadly comprising a number of irrigation spans and a control system configured to operate single speed drive motors of the irrigation spans in a start-up mode, full speed mode, and wind-down mode. In the start-up mode, the motor controller gradually increases the drive motor speed from 0 rpms to a full speed by ramping a voltage applied to the drive motor from a starting voltage to a full speed voltage according to a start-up voltage profile over a start-up time interval. In the full speed mode, the motor controller operates the drive motor at a full speed voltage. In the wind-down mode, the motor controller gradually decreases the drive motor speed from full speed to 0 rpms by ramping the voltage applied to the drive motor from the full speed voltage to an ending voltage according to a wind-down voltage profile over a wind-down time interval.
