Soil spectral calibration library and estimation service

The Global Soil Spectral Calibration Library and Estimation Service, recently established by the Global Soil Partnership and implemented by the Global Soil Laboratory Network, will generate enormous efficiencies and constitute an important global public good to help the world address the climate crisis through better understanding of soils for improving productivity and reversing land degradation.

Soil spectroscopy is a fast, cost-effective and environmental-friendly technique that uses the interaction of electromagnetic radiation with soils to estimate soil properties, such as the levels of acidity, organic carbon, nitrogen and water retention. These determine the health and usability of soils.
