The objective was to examine and compare the ability of near- and mid-infrared diffuse reflectance spectroscopy to determine the composition of dried dairy manures. Samples (n=99) were dried at 60 degrees C, ground and scanned in the near-infrared in a rotating sample cup on a Foss-NIRSystems model 6500 scanning monochromator, and in the mid-infrared on a Digilab FTS60 Fourier transform spectrometer using a custom-made sample transport device.
