Covariates selected as predictors for each soil attribute. The predictors selected by the VSURF function were filtered, eliminating all the predictors with a correlation greater than 0.6. The upper and lower sets correspond to the portion of the soil database used for selecting the covariates. Pr: Precipitation, Temp: Temperature, SD: standard deviation, CV: Coefficient of variation, TPI: Topographic Position Index.
