GeoPearl: SOM-content under arable land 1000m
Model predictions on SOM-content under arable land( Report: https://edepot.wur.nl/556312).
Predictions with a model ensemble at fixed depths of 15, 45, 80 and 120 cm.
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. Prediction
