    Abstract: A downforce controller for an agricultural implement having a double-acting hydraulic cylinder. The cylinder is configured to be coupled to an agricultural row unit and an agricultural toolbar for transmitting a net downforce between the agricultural toolbar and the agricultural row unit. A first pressure in the first chamber of the cylinder and a second pressure in the second chamber of the cylinder having counteracting effects on the net downforce. A manifold coupled to the cylinder is in fluid communication with the first chamber. A pressure control valve supported by the manifold is in fluid communication with the manifold and the first chamber.

    Abstract: A rotary analysis apparatus and related methods are disclosed. The apparatus generally includes a rotary machine operable to rotate or spin a removable disk-type analytical cartridge. The cartridge includes a plurality of fluidly isolated processing trains for processing multiple samples simultaneously. Each process train includes an extractant mixing chamber, slurry filtration chamber, supernatant collection chamber, and reagent mixing chamber in fluid communication. In one use, soil sample slurry is prepared and added to the extractant mixing chamber. The slurry is mixed with an extractant by rotating the cartridge to separate out an analyte from the mixture. A sediment filter in the filtration chamber deliquifies and traps soil particles to produce clear supernatant. A color changing reagent or fluorescent agent may be mixed with the collected supernatant for subsequent colorimetric, fluorescent, turbidimetric, or other type of analysis.

    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. 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 (i.e. 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 sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or other samples. A soil collection system is disclosed which captures and directs
