Soil Organic Carbon Stock Maps for Belgium
The Belgian soil organic carbon (SOC) stock maps for topsoils (0-30 cm) were composed of 2 regional SOC stock maps. For the regional maps a different approach was used for agricultural land as compared to forest. The maps are based on digital soil mapping approaches using empirical models calibrated to predict the SOC stock and using covariates that are available at a sufficient resolution at the regional scale. All maps are strongly dependent on the Belgian Soil Map (texture and drainage parameters). The regional maps were compiled at a finer resolution (10m x 10m and 40m x 40m grid cells). Next they were joined (40m x 40m grid cells) and finally scaled up to the required 1 by 1 km grid cells. This was done using the following tools: block statistics (mean), mosaic to new raster (mean), project to raster, block statistics (mean), resample (nearest neighbour) and project raster.
Given the different origin of the individual maps, the uncertainty varies between maps. For instance, a map of the 90% confidence interval of the SOC stocks was produced for agricultural soils in Wallonia based on a Monte Carlo Approach taking into account both the measurement and the model uncertainties. For Flemish forest soils, spatial and analytical uncertainties were taken into account using bootstrapping techniques. For Flemish agricultural soils, the uncertainty reported is the model uncertainty on point estimates for each data point, in which the estimated model parameters are simulated 1000 times as being independent normal distributed variables using their model estimation and standard error as distribution parameters. No additional uncertainty is taken into account for the conversion functions that use the stochastic variables "bulk density".
The SOC stock maps are the first comprehensive maps for Belgium integrating grasslands, croplands and forests. There are two versions of the SOC stock maps for Belgium: 1) resolution of 40m x 40m in the coordinate reference system Lambert72 and 2) resolution of 1km x 1km in the coordinate reference system WGS84. The metadata are available and allow assessing the uncertainties of the stock estimates in the different component maps.

- Purpose
-
The Belgian Soil organic carbon (SOC) stock maps for topsoils (0-30 cm) were created answering a call from the Intergovernmental Technical Panel on Soils of the Global Soil Partnership (GSP) for regional SOC data. Based on this regional data in a unique 1km grid the Global Soil Organic Carbon Stock (GSOC) Map was compiled by the GSP.

Landbouwers, erosiecoördinatoren of bedrijfsplanners kunnen een aanvraag indienen voor het toekennnen van code A (andere erosiegerelateerde gronden) aan geografische eenheden of aan percelen met zeer lage tot verwaarloosbare bodemerosie. Bij een positieve beoordeling door ALBON wordt de (eventueel aangepaste) geografische eenheid toegevoegd aan de bestaande kaart van de 'Andere erosiegerelateerde gronden'.
