NIRs spectra of each corn silage sample in the wavelength range (i.e., 1100–2500 nm) (a) and variable importance in total mycotoxins count and sums with the Random Forest (RF) model (b,c). The bands at 1430, 1470, 1820, 2140, and 2180 nm related to total fungal infection could be assigned to the first overtone of the OH stretching modes of glucose, NH in most amino acids, and CH combination bands in cis unsaturation [53].
