1. A soil analysis device comprising:
- a reservoir configured to store a cleaning fluid;
a mixing chamber coupled to the reservoir and configured to take one or more measurements from a soil solution sample stored within the mixing chamber;
a mixing assembly coupled to the mixing chamber and configured to mix contents of the mixing chamber;
a drain box coupled to the mixing chamber and configured to evacuate the contents of the mixing chamber;
an air source configured to move the cleaning fluid from the reservoir to the mixing chamber;
a control system configured to, in response to determining that the one or more measurements have been completed;
cause the drain box to evacuate a substantial portion of the soil solution sample from the mixing chamber,cause the air source to move at least a portion of the cleaning fluid from the reservoir to the mixing chamber,cause the mixing chamber to move the portion of the cleaning fluid within the mixing chamber to clean leftover particulates of the soil solution sample from the mixing chamber,cause the drain box to evacuate the portion 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.
