  abstract = {{T}he applicability of near-infrared reflectance spectroscopy ({NIRS}) as tool for estimating mineral soil constituents was assessed over a wide range of highly weathered soils in {M}adagascar. {T}he predictions were based on two types of methods, chemometric methods using multivariate calibration models from partial least squares ({PIS}) regressions, and the use of spectral signatures of specific minerals. {T}he predictions of mineralogical properties of soils using chemometric methods were poor, except for the quantification of iron oxides extracted with citrate bicarbonate dithionite ({CBD}) ({R}-cv(2) = 0.80). {S}oil minerals (kaolinite, gibbsite, goethite and hematite) were also estimated by {NIBS} but with less accuracy ({R}-cv(2), = 0.50-0.80). {T}he predictions of kaolinite and gibbsite contents were improved by the use of the peak intensity of the first derivative spectra, situated at around 2205 nm for kaolinite and 2265 nm for gibbsite. {T}he results indicate that {NIRS} can be used as a rapid analytical technique to simultaneously estimate the main minerals of highly weathered ferralitic soils with acceptable accuracy.},
