Analyzing the share of amorphous silica in mixtures with different soil minerals using fourier transform infrared spectroscopy and PLSR chemometrics
Oliver Hunfeld, Ruth H. Ellerbrock, Mathias Stein, Carsten W. Müller et autres
Amorphous silica (ASi) improves key soil functions and crop productivity but is difficult to quantify due to complex mineral mixtures and time-consuming chemical analyses. This study explored the possibility of using Fourier-transform infrared spectroscopy (FTIR) in combination with partial least-squares regression (PLSR) …
