Abstract

An attempt to automated the interpretation of mid-infrared (MIR) spectral profiles of humic acids (HAs) from volcanic ash soils was carried out with the aid of plots displaying the valuable importance for projection (VIP) scores computed by partial least squares (PLS) regression. A set of about 200 dependent variables from whole soils and HAs was examined in 30 uncultivated and agricultural soils with the PLS-VIP method in order extract objective information about the extent to which the MIR intensities may be useful to forecast quantitative and qualitative agroecological and biogeochemical factors, as well as to ascribe individual bands to structural or functional HA variables which were determined by independent multianalytical approaches.
