How accurate are pedotransfer functions for bulk density for Brazilian soils?

How accurate are pedotransfer functions for bulk density for Brazilian soils?

The aim of this study was to evaluate the predictive capability of PTFs available in the literature to estimate soil pb in different regions of Brazil, using different metrics (mean absolute error (MAE), root mean squared error (RMSE), mean error (ME) and regression error characteristic (REC) curve).
