OxSR: Soil Iron Oxides via Diffuse Reflectance
Calculate the ratio of iron oxides, hematite and goethite, in
soil using the diffuse reflectance technique. The Kubelka-Munk theory,
second derivative analysis, and spectral region amplitudes related to
hematite and goethite content are used for quantification (Torrent,
J., & Barron, V. (2008) <doi:10.2136/sssabookser5.5.c13>).
Additionally, the package calculates soil color in the visible
spectrum using Munsell and RGB color spaces, based on color theory
(Viscarra et al. (2006) <doi:10.1016/j.geoderma.2005.07.017>).
