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.
