Accuracy of pedotransfer functions to estimate soil bulk density in Brazil.

Soil bulk density is an important soil physical property, used as a quality indicator. Its variation influences soil water content and carbon stock estimates. This study aims to evaluate the accuracy of pedotransfer functions that predict bulk density in Brazil. The predictive capacity of 14 pedotransfer functions were evaluated using the Pearson correlation (r), the mean standard error (MSE), and the root mean square error (RMSE). The best results were obtained by Benites et al. (2006) - B, Botula (2013), and Souza et al. (2016). However, the inaccuracy is not acceptable for some applications and new functions considering a hierarchical system of soil data considering soil class and depth (surface or subsurface), land use (agriculture, pasture, and forest) and management (no-tillage, conventional or livestock farming forest integration) will be developed and tested.
