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. Further, the apparatus helps farmers to increase crop yields, optimize input costs, and protect the environment by supporting fertilizer efficiency.
