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 to produce a sample slurry. The system includes a chemical analysis sub-system which processes and analyzes the prepared slurry for quantifying multiple analytes and/or chemical properties of the sample. The chemical analysis sub-system may be embodied in a multi-layered microfluidic manifold processing substrate comprising microfluidic devices which extract and quantify the concentration of analytes or other chemical parameters associated with the sample.

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 first to produce a sample slurry. The system includes a multi-layered microfluidic manifold chemical analysis substrate configured to provide a temperature-compensated concentration of analytes or other chemical properties associated with the sample. The system utilizes a programmable controller, temperature sensor, and absorbance measurement device for that purpose. The system can be used to analyze various type of agricultural-related samples including soil, vegetation, manure, milk or other.

Abstract: Systems, methods, and apparatus for selection of crop-input varieties. Multiple varieties of seeds may be planted with a row unit seed hopper having a plurality of compartments for receiving seed, each compartment having a seed passage through which seeds pass under gravity. A seed transfer actuator is disposed within or below the row unit seed hopper and is in communication with each of the seed passages and is configured to selectively open the seed passage of one of the plurality of compartments to permit the seeds therein to pass into the seed pool of a seed meter while closing the seed passage of other of the plurality of compartments to prevent the seeds from the other plurality of compartments passing into the seed pool of the seed meter.

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 manure samples.
