Effects of Polyvalent Cations on FTIR Spectra of Organic Matter–Cation Associations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The composition of soil organic matter (SOM) can be characterized by functional groups in the organic matter (OM). The carboxylic acid and carboxylate groups of OM show specific absorption bands in Fourier‐transform infrared (FTIR) spectra. However, cation–OM interactions may affect absorption bands and limit spectral interpretation
