摘要： A wind tunnel device is provided herein that enables the wind tunnel to transform between two modes of operation and/or to refresh/recondition air within the tunnel. The wind tunnel device may provide selective diversion of airflow within the wind tunnel. The diversion of airflow may enable the wind tunnel device to include a multi-configurable wind tunnel that can be operated as either an open-return wind tunnel or a closed-return wind tunnel. Additionally, or alternatively, the diversion of airflow may enable the wind tunnel device to recondition air within a closed-return wind tunnel.

摘要： 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.

摘要： A wind tunnel device may include a waste disposal unit configured to collect fluid from a droplet extractor positioned in a wind tunnel. The waste disposal unit may include a drain line and a liquid trap integrated in the drain line. The liquid trap may be adjustable during operation of the wind tunnel to accommodate different tunnel operating conditions (e.g., wind speeds) such that liquid waste does not backflow into the wind tunnel.

摘要： 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.

摘要： 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.

摘要： 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.
