1. A soil analysis device comprising:
- one or more reservoirs configured to store an extractant and/or a cleaning fluid;
a mixing chamber coupled to the one or more reservoirs and configured to receive the extractant from the one or more reservoirs and to receive raw soil samples;
a mixing assembly coupled to the mixing chamber and configured to mix contents of the mixing chamber;
a measurement cell coupled to the mixing chamber and configured to analyze a soil sample solution;
a drain box coupled to the mixing chamber and configured to evacuate the contents of the mixing chamber; and
a control system configured to;
cause the mixing chamber to receive an amount of the extractant from the one or more reservoirs;
cause the mixing chamber to receive a raw soil sample;
cause the mixing assembly to mix contents of the mixing chamber to produce the soil sample solution;
cause the measurement cell to receive and analyze the soil sample solution;
cause the drain box to evacuate a substantial portion of the soil sample solution from the mixing chamber;
cause the mixing chamber to receive an amount of the cleaning fluid from the one or more reservoirs;
cause the mixing assembly to move the amount of the cleaning fluid within the mixing chamber to clean leftover particulates of the soil sample solution from the mixing chamber; and
cause the drain box to evacuate the amount of the cleaning fluid from the mixing chamber.

Abstract
A soil analysis device is configured to create a soil sample solution. The device includes a reservoir configured to store an extractant, a mixing chamber coupled to the reservoir and configured to receive extractant from the reservoir and to receive a raw soil sample, and a control system. The control system is configured to determine an amount of extractant needed to produce, from the raw soil sample, a soil sample solution with a particular soil-to-extractant ratio and configured to cause the determined amount of extractant to be transferred from the reservoir to the mixing chamber.
