Abstract
A soil analysis device and a method are disclosed for measuring characteristics of a soil sample. A mixing chamber combines a soil sample and an extractant into a liquid mixture. A filtration system receives and filters the liquid mixture. The filtered liquid mixture is transmitted to a measurement cell. The measurement cell is coupled to a light source so that light propagating from the light source is attenuated and/or reflected by the liquid mixture and is measured by one or more optical detectors that are also coupled to the measurement cell. The optical detector generates an attenuation spectrum and/or a reflection spectrum indicating light received by the one or more detectors at different wavelengths. The attenuation and/or reflection spectrum is used to determine the characteristics of the soil sample.
