Abstract: Computer-implemented systems and methods predict behavior of sprays based on receiving a selection of one or more variables affecting spray. Relative amounts of the droplets forming the spray are grouped into various droplet size classes, where each droplet size class represents a range of droplet sizes. The relative amounts of the spray in the classes is visually depicted on a computer display according to a distribution of droplets, a volume of spray falling within the droplet size classes, a chart depicting relative amounts of the spray as a function of droplet size, or according to a spray quality based on environmental factors.

Abstract: A soil analysis device is configured to create a soil sample solution. The device includes a reservoir configured to store an extractant, a mixing chamber coupled to the reservoir and configured to receive extractant from the reservoir and to receive a raw soil sample, and a control system. The control system is configured to determine an amount of extractant needed to produce, from the raw soil sample, a soil sample solution with a particular soil-to-extractant ratio and configured to cause the determined amount of extractant to be transferred from the reservoir to the mixing chamber.

Abstract: An agricultural spray may be produced by admixing citric acid and glutamic acid with a metal salt and a pesticide or other agricultural chemical containing components capable of precipitating with the metal salt in the admixture. The citric acid and the glutamic acid chelate with the metal salt to provide a stability and compatibility-enhancing composition, thereby preventing the metal salt from forming an insoluble solid within the admixture. Such a composition may be produced by admixing citric acid and glutamic acid at a molar ratio of about 6.8:0.5 to about 1:0.29. The composition may include a metal sat, citric acid and glutamic acid in a molar ratio of about 1:6.8:0.5 to about 1:1:0.29 and a pesticide.

Abstract: A wind tunnel device defines a cyclical tunnel to receive continuous airflow. Airflow is delivered through the tunnel to a testing region that includes a first portion carrying an arm including a spray tip configured to spray particulates in the testing region at an angle, and a second portion including an enlarged cutout region configured to receive the angled sprayed particulates. As airflow carries the angled spray particulates into the second portion, the enlarged cutout region enables the spray particulates to pass through and exit the second portion of the testing region. Analysis in the second region may be conducted through transparent walls free of openings to minimize exposure of the spray particulates to the exterior of the device. A scrubber is adapted to extract spray mist from the airflow as the airflow exits the testing region and is re-circulated through the cyclical tunnel.

Abstract: The present application relates generally to a demonstration kit for various nozzles. The demonstration kit may include a spray assembly and a control assembly. The spray assembly may include a case having a base and a cover rotatably coupled to the base, a plurality of back wall panels configured to be secured to a sidewall of the base, a boom connected to an interior surface of the case, and one or more nozzles connected to the boom and repositionable along a length of the boom. The control assembly includes at least one pump that when in an operating orientation is fluidly connected to the one or more nozzles and a portable power supply in electrical communication with the at least one pump.

Abstract: The application is generally directed towards an airfoil for a fluid delivery tube. The airfoil includes a securing member operably connecting the airfoil to the tube, a fin extending downward and outward from the securing member and terminating in a tip, a shield extending inward and downward from the tip of the fin, and an air guide extending from a first end of the shield.

Abstract: A chelated zinc adjuvant composition includes water, an effective amount of a micronutrient consisting of zinc chelated with an organic acid and an organic amine, a mono-, di- or polysaccharide and an alkyl polysaccharide. The adjuvant has a pH of up to 6.5. When admixed with a pesticide capable of precipitating with the zinc, due to the zinc being chelated, the zinc is prevented from precipitating with the pesticide and is available for uptake. When the adjuvant composition is applied in seed, soil, foliage or fruit applications, zinc uptake is improved.

Abstract: A filtration system for a soil analysis device and methods of pressure filtration and automated cleaning are disclosed for generating filtrate used in measuring characteristics of a soil sample and preparing the filtration system for repeated measurements. A mixing chamber combines a soil sample and an extractant into a liquid mixture. The filtration system receives and pressure filters the liquid mixture to quickly generate filtrate used to measure characteristics of the sample. The filtrate is passed to a measurement cell for analysis. Once the analysis is complete, the filtration system performs a cleaning process in preparation to receive a subsequent liquid mixture from another soil sample.

Abstract: An agricultural sprayer assembly includes a wheeled carriage, a chassis, and a spray delivery system. The wheeled carriage has a number of adjustable support legs (e.g., four), each formed of hydraulically coupled and actuated upper and lower leg sections or members. The chassis is supported on the wheeled carriage, at an adjustable clearance height defined by the operational height of the support legs. The spray delivery system includes a spray boom coupled to a boom support, and an actuator coupled to the boom support and the chassis. The actuator is configured to adjust the height of the spray boom with respect to the clearance height of the chassis.

Abstract: The application is generally directed towards a drop nozzle for an agricultural sprayer. The drop nozzle can be used to reduce spray drift as liquids are deposited by the sprayer. The drop nozzle includes a valve assembly including a shutoff valve, a tube operably connected to the valve assembly, and an airfoil connected to the tube. The shutoff valve selectively prevents fluid flow from the valve assembly to the tube and the airfoil directs airflow around one or more portions of the drop nozzle.
