%description
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>).
