  • Publication number: 20100283994
    Abstract: The nitrate-nitrogen concentration in soil is estimated based on the nitrate-nitrogen 200 nm absorption peak. In one embodiment, a device measures the attenuation spectrum of a soil-extractant mixture over a wavelength range that includes wavelengths in the vicinity of the 200 nm absorption peak (the spectral operating range) and then determines the nitrate-nitrogen concentration based on the attenuation spectrum.

  • Publication number: 20100283993
    Abstract: A system and a method are disclosed for combining a soil sample and extractant in a mixing chamber to produce a liquid extractant-soil mixture. A portion of the liquid extractant-soil mixture is directed from the mixing chamber through a sample measurement chamber coupled to the mixing chamber. The sample measurement chamber is coupled to a light source so that light propagates from the light source through the portion of the liquid extractant-soil mixture to an optical detector which generates an attenuation spectrum indicating light received by the detector at different wavelengths. The sample measurement chamber may include an attenuation cell having a specified optical path between a first measurement window and a second measurement window and angular surface directing particulates in the liquid extractant-soil mixture away from the attenuation cell.
