Soils diffuse reflectance infrared Fourier

Direct NIR or MIR measurements of whole soil can be made using attenuated total reflectance (ATR) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) samplers. This type of measurement detects only components on the surface and so has severe limitations when information about the bulk soil is needed [4],... [Pg.179]

Figure 1.4 Comparison of diffuse reflectance infrared Fourier transform spectral (DRIFTS) patterns between the yellow-brown soil on the shoe (red) and the < 50 pm fraction in the stony soil from the riverbank (blue). Shoe and riverbank samples were both ground using an agate mortar and pestle. (From Fitzpatrick, R. W., Raven, M. D., and Forrester, S. T., CSIRO Land and Water Client Report CAFSS 027, 2007.
