Summary

This initiative addresses barriers to adoption of soil reflectance spectroscopy by proposing a globally accessible calibration library and estimation service built on high-quality soil archives and supported by international networks. The service leverages the capability of spectroscopy to rapidly estimate multiple soil properties from non-destructive light-based measurements, with particular potential benefit for developing countries with limited soil analytical capacity. The approach overcomes obstacles including laboratory standardisation issues, poor reproducibility, and the expense of building local spectral libraries.

UK applicability

The UK possesses established soil survey infrastructure and analytical capacity; however, access to this global estimation service could enhance soil monitoring efficiency for UK farmers and land managers, particularly as a screening tool for targeted conventional analysis. Applicability depends on whether the global calibration library adequately represents British soil types and whether the service integrates with existing UK soil classification and survey schemes.

Key measures

Soil reflectance spectroscopy data; soil properties estimated from spectral calibration; library diversity and quality metrics

Outcomes reported

The study proposes a freely available Global Soil Spectral Calibration Library and Estimation Service based on soil reflectance spectroscopy and the USDA Kellogg Soil Survey Laboratory archives. The service aims to enable rapid, inexpensive estimation of multiple soil properties using light-based spectroscopic measurement.
