    摘要： In one embodiment a first light plane is generated across the passageway by a first LED emitter array. A corresponding photodiode receiver array detects particles passing through a first number of light channels comprising the first light plane. In a second embodiment a second light plane is generated across the passageway at 90 degrees from the first light plane and longitudinally offset from the first light plane by a second LED emitter array. A corresponding photodiode receiver array detects particles passing through a second number of light channels comprising the second light plane. The second light plane is capable of identifying particles in a third dimension that may go undetected when passing through the first light plane. The raw output signals generated by respective photodiodes is normalized, analyzed and characterized to differentiate between particles passing through light planes as individual particles or groups of overlapping particles to be separately counted.

    摘要： Described herein are systems and methods for determining state data for agricultural parameters during agricultural applications and providing spatial state maps. In one embodiment, a computer implemented method comprises obtaining as applied data of an agricultural implement as the agricultural implement passes through a field for an agricultural application. The computer implement method also includes processing the as applied data to calculate data for a parameter of the agricultural application and determining state data (e.g., quality indicator state) for each row unit based on the data for the parameter and at least one of default configuration settings or user configuration settings for the quality indicator state.

    摘要： A liquid distribution system for a crop sprayer includes a product tank configured to contain a liquid, a pump in fluid communication with the product tank, a plurality of nozzles carried by a boom and configured to receive the liquid from the pump, a recirculation line connecting the plurality of nozzles to the product tank, and a bypass line connecting the pump to the product tank. The recirculation line includes an on/off valve configured to alternatively block or permit flow through the recirculation line. The bypass line includes a second on/off valve configured to alternatively block or permit flow through the bypass line. Related crop sprayers and methods are also disclosed.

    摘要： An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (e.g., mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The preparation sub-system may comprise a slurry recirculation flow loop configured with devices to stir, measure, and adjust a water to solids ratio of the slurry.
