    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: An agricultural trench depth sensing system having a trench implement adapted to be disposed in a soil trench opened in a soil surface. In one embodiment an ultrasonic sensor detects a distance to an upper surface of said trench implement or a target disposed thereon. In another embodiment, said trench implement includes one or more fingers which rotate with respect to said trench implement to detect the soil surface relative to said trench implement. In another embodiment, said trench implement includes side sensors for detecting the sidewall of the soil trench.

    Abstract: Systems, methods and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar, for controlling operative height of a toolbar and sections of a toolbar and for folding a toolbar between a work position and a transport position. A ground engaging wheel and an actuator are coupled to the toolbar. In one embodiment, a fluid control system is responsive to a command signal to modify the actuator pressure such that the actuator pressure corresponds to a desired pressure.
