ptfs4br: Pedotransfer Functions for Soil Applications in the Brazilian Territory

The ptfs4br contains a collection of pedotransfer functions (PTFs) built using open legacy data collected in the Brazilian territory. PTFs are empirical models estimated to predict the values of soil properties from other soil properties and environmental covariates that are easier or cheaper to measure or that are more readily available. The present version contains PTFs for predicting carbon and organic matter content.
