Abstract: Disclosed is a soil sampling device designed to enhance efficiency and accuracy in soil analysis processes. The soil sampling device includes a computer system for data storage and processing, along with a display screen for visualizing collected scan data. Equipped with a GPS sensor, the device precisely identifies soil sampling locations. A sampling chamber ensures sample integrity by blocking ambient light during spectroscopy readings and facilitates sample disposal post-testing. Operating with a core rod column and an auger, the device efficiently extracts soil samples while homogenizing materials. A driver mechanism propels the auger, supported by a homogenization cylinder for mixing soil samples. Additional features include a stomp pad for depth control during sampling, a calibration standard mechanism for sensor calibration, and an sampling element/auger cover for sample containment.

Abstract: Disclosed are improved soil mapping methods and apparatus that enable a user to efficiently analyze soil and create accurate soil maps to enable the user to determine soil content. The apparatus includes a probe cylinder, an extractor cylinder, a collector assembly, a first stepper motor, a roller assembly, a mixing motor, a contact probe, a cleaning brush motor, a bracket assembly for a mix motor, brush motor, and probe, an extruded aluminum bracing, a gear track, a second stepper motor, a scraper assembly, a third stepper motor, a probe, and one or more hyperspectral sensors. The apparatus relies on less expensive, faster, and more accurate data points that provide actionable real-time information by automating the current labor-intensive soil testing process. The apparatus serves the agricultural industry by advancing precision soil mapping technology to support proactive and efficient fertilizer use.
