(4) Spectral Reflectance of Soil. Soil reflectance (Figure 2-22) typically increases

with wavelength in the visible portion of the spectrum and then stays relatively constant

in the near-IR and shortwave IR, with some local dips due to water absorption at 1.4 and

1.9 m and due to clay absorption at 1.4 and 2.2 m (Lillesand and Kiefer, 1994).
