Spectroscopy, which is always associated with chemometrics, is a versatile technique that is applied in several areas of science. It is fast, non-destructive, low-cost and, in addition, “clean”, requiring few or no reagents. The latter factor aligns the tool with green chemistry.

The current project aims to strengthen a multidisciplinary team that is familiar with spectroscopy, chemometrics, pedology, and soil fertility in order to adapt and incorporate various routine methods used in soil laboratories, including the most pollutant ones, to the principles of green chemistry.

This research intends to foster the incorporation of spectroscopy techniques into routine soil analyses at Embrapa Soils, validating them by simultaneously determining various soil attributes to replace traditional methods, while reducing waste production and costs and time involved in performing analyses.
