Using Variable Selection and Wavelets to Exploit the Full Potential of Visible-near Infrared Spectra for Predicting Soil Properties

In soil spectroscopy a series of strategies exists to optimise multivariate calibrations. We explore this issue with a set of topsoil samples for which we estimated soil organic carbon (OC) and total nitrogen (N) from visible-near infrared (vis-NIR) …
