  • Method for soil content prediction based on a limited number of mid-infrared absorbances
    Patent number: 7671336
    Abstract: A single absorbance value was found in the mid infrared (mid-IR) region that correlated directly to soil nitrate content while not being influenced by other components in the soil, such as carbonate and organic matter. Using one or two absorbance values, at which interference from other ions is a minimum, to predict a component's concentration as opposed to the conventional method of using a continuous spectrum allows for an in-situ real-time soil nitrate content sensor.
    Type: Grant
    Filed: September 14, 2006
    Date of Patent: March 2, 2010
    Assignee: The Regents of the University of California
