Title:Main Title: Rapid assessment of black carbon in soil organic matter using mid-infrared spectroscopy
Description:Abstract: Comprehensive data sets for understanding the global distribution of black carbon (BC) in soil are currently lacking because of the considerable expenditure of time needed for BC analyses. Here we report that reliable screening of soil BC can be achieved using mid infrared spectroscopy (MIRS) and multivariate data analysis. Calibration models were built employing 309 samples from different soil depths and land-use systems in America, Asia and Europe, characterized for soil organic carbon (SOC) and benzene polycarboxylic acids (BPCA) as specific BC markers. About 99% of total SOC variability was explained by local calibrations with an error of prediction 0.8), partly reflecting different BC quality. A measure of the latter is the mellitic acid-C percentage. It also correlated with MIRS patterns (R²≥0.6%), which thus even allowed to classify BC according to its degree of condensation.
