Successful international collaboration to study changes in soil organic carbon stocks

Successful international collaboration to study changes in soil organic carbon stocks

Researchers (Gábor Szatmári and László Pásztor) from the Department of Soil Mapping and Environmental Informatics working with a senior scientist (Gerard Heuvelink) from ISRIC – World Soil Information and Wageningen University & Research have studied soil organic carbon (SOC) stock change between 1992 and 2010 at multiple aggregation levels in Hungary. Their results showed that both the predictions and uncertainties of the average SOC stock change were smaller for larger spatial supports, while spatial aggregation also made it easier to obtain statistically significant SOC stock changes. The latter is important for carbon accounting studies that need to prove in Measurement, Reporting and Verification protocols that observed SOC stock changes are not only practically but also statistically significant. Their results and findings have been published in Geoderma (D1, IF: 6.114):
