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.

20. A soil analysis device comprising:
-
a mixing chamber including an inlet configured to receive a cleaning fluid and a waste outlet, the mixing chamber configured to receive an extractant and raw soil samples, wherein the extractant and the raw soil samples form a soil sample solution; a mixing assembly coupled to the mixing chamber and configured to mix contents of the mixing chamber; at least one measurement device coupled to and/or disposed in the mixing chamber, the at least one measurement device configured to analyze the soil sample solution; and a control system configured to cause the mixing assembly to move an amount of the cleaning fluid within the mixing chamber to clean leftover particulates of the soil sample from the mixing chamber responsive to analyzing the soil sample solution and removing at least some of the soil sample solution from the reservoir via the waste outlet. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A soil analysis device comprising:
-
one or more reservoirs configured to store at least one of an extractant or a cleaning fluid; a mixing chamber including an inlet coupled to the one or more reservoirs and a waste outlet, the mixing chamber configured to receive the extractant and raw soil samples, the mixing chamber configured to take one or more measurement from a soil solution sample that includes the extractant and the raw soil samples; a control system configured to cause the mixing assembly to move an amount of the cleaning fluid within the mixing chamber to clean leftover particulates of the soil sample from the mixing chamber responsive to analyzing the soil sample solution and removing at least some of the soil sample solution from the reservoir via the waste outlet.

39. A soil analysis device comprising:
-
one or more reservoirs configured to store at least one of an extractant or a cleaning fluid; a mixing chamber including an inlet coupled to the one or more reservoirs and a waste outlet, the mixing chamber configured to receive the extractant and raw soil samples, the mixing chamber configured to take one or more measurement from a soil solution sample that includes the extractant and the raw soil samples; at least one flow meter configured to measure an amount of at least one of the extractant or the cleaning fluid transferred from the one or more reservoirs into the mixing chamber; and a control system configured to cause the mixing assembly to move an amount of a cleaning fluid within the mixing chamber to clean leftover particulates of the soil sample from the mixing chamber responsive to analyzing the soil sample solution and removing at least some of the soil sample solution from the reservoir via the waste outlet.
