Abstract: A spraying system that includes at least one camera to determine for at least one nozzle spray angle, average of spray angle, standard deviation of spray angle, relative pressure, absolute pressure, relative flow rate, absolute flow rate, percent plugged, and/or spray pattern uniformity/variability of the spray from the at least one nozzle.

Abstract: A system having: a boom; at least one nozzle assembly attached to the boom; and a nozzle or a second nozzle assembly; wherein the at least one nozzle assembly and the second nozzle assembly each comprise a nozzle and at least one light; wherein the at least one light is disposed to illuminate a spray from an adjacent nozzle assembly or nozzle.

Abstract: A system having a boom; a plurality of cameras attached to the boom; and a plurality of lenses on each camera; wherein not all lenses have a same field of view.

Abstract: A system comprising a boom, a plurality of nozzles disposed along the boom, a light disposed on the boom to illuminate a spray pattern from at least one nozzle, a camera disposed on the boom to capture a first image of a spray from the at least one nozzle at a first time and a second image of no spray from the at least one nozzle at a second time, and a processor to calculate a difference between the first time and second time to determine a pulse width modulation of the at least one nozzle.

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.
