New article from Pacini et al. 2025

Pacini et al. (2025) evaluated the potential of mid-infrared spectroscopy (MIR), a less expensive and higher throughput technique than Rock-Eval® thermal analysis, to quantify the proportion of soil organic carbon (SOC) stable over a century. They compiled a spectral library of more than 1,800 records obtained by scanning samples from the French Soil Quality Monitoring Network in order to calibrate a model using MIR data to predict the proportion of SOC stable over a hundred years. The model provided accurate predictions showing that MIR spectra contain relevant information on the biogeochemical stability of SOC. Transferring the model obtained from French data to data acquired from German and Finnish soil samples resulted in a decrease in its accuracy.
