    Abstract: 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 are disclosed. 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. The object of the claimed invention is a slurry stirring device (8030) comprising an elongated housing (8094) defining a vertical centerline and a stirring chamber, a slurry inlet (8032) configured to receive the slurry, a slurry recirculation inlet (8033a) configured for fluid coupling to a closed slurry recirculation flow loop, and a slurry recirculation outlet (8033b) configured for fluid coupling to the slurry recirculation flow loop; and a rotatable blade mechanism configured to maintain the slurry in an agitated mixed condition in the stirring chamber.

    Abstract: A coulter assembly for collecting soil samples from an agricultural field in one embodiment comprises an annular collection blade configured for penetrating soil to capture a sample, an annular cam ring configured for stationary mounting to a frame of an agricultural vehicle and comprising a cam track, a blade hub coupled to the blade for rotatably supporting the annular collection blade from the annular cam ring, and a movable sample collector mounted to the annular collection blade. The moveable sample collector is configured and operable for extracting a soil sample as the annular collection blade is rotated through the soil. The moveable sample collector in one embodiment comprises a piston mechanism including a cylinder and rod movably disposed therein which actuated by the annular cam ring to alternatingly open and close a collection end of the cylinder as the annular collection blade rotates through the soil.

    Abstract: A double diaphragm slurry pump (7080) comprises: a pump body (8200) defining a vertical longitudinal axis (LA) and first (8201) and second (8202) pumping chambers; an inlet flow manifold (8203) and an outlet flow manifold (8204) coupled to the pump body; a first pump head (8230a) coupled to the body adjacent the first pumping chamber, the first pump head comprising a longitudinal flow bore (8231) separate from the first pumping chamber and fluidly coupled to the inlet and outlet flow manifolds, an upper air vent bore (8232), and a lower slurry exchange bore (8233), the upper air vent bore and lower slurry exchange bore each fluidly coupling the longitudinal flow bore in turn to the first pumping chamber; and an operating shaft (8240) coupled to a resiliently deformable diaphragm (8241) disposed in the first pumping chamber; wherein the shaft is moveable in a pump stroke to pump a fluid through the longitudinal bore of the first pump head and the first pumping chamber from the inlet flow manifold to the outlet flow manifold; and wherein the upper air vent bore (8232) is smaller in diameter than the lower slurry exchange bore (8233) such that air is preferentially ejected from the first pumping chamber rather than slurry during the pump stroke.
