GeoPearl: SOM-content under arable land 250m

Model predictions on SOM-content under arable land (see: Report: https://edepot.wur.nl/556312 ):

'Predictions with a model ensemble at fixed depths of 15, 45, 80 and 120 cm on a 250m grid.

Predictions using an ensemble of Random Forests and Gradient Boosting, with covariates from

the SoilGrids 2017 model (Hengl et al. 2017) and a spatial cross-validation procedure.

The model was applied on log-transformed observations of SOC. Models result were back-

transformed and converted to SOM by multiplying SOC predictions with 1.743.'
