Author(s): KOTLAR, A. M.; LIER, Q. de J. van; BARROS, A. H. C.; IVERSEN, B. V.; VEREECKEN, H. There has been much effort to improve the performance of pedotransfer functions (PTFs) using intelligent algorithms, but the issue of covariate shift, i.e., different probability distributions in trai... ... |
Author(s): REIS, A. M. H. dos; TEIXEIRA, W. G.; FONTANA, A.; BARROS, A. H. C.; VICTORIA, D. de C.; VASQUES, G. M.; SAMUEL-ROSA, A.; OTTONI, M. V.; MONTEIRO, J. E. B. de A. Bulk density (BD) is a soil physical property used as a soil quality indicator and variations in this measurement influence soil water content and carbon stock estimates. This study aims to compile a... ... |
Author(s): OTTONI FILHO, T. B.; LEAL, I. F.; MACEDO, J. R. de; REIS, B. C. B. Despite the large applicability of the field capacity (FC) concept in hydrology and engineering, it presents various ambiguities and inconsistencies due to a lack of methodological procedure standardi... ... |
Author(s): HUF DOS REIS, A. M.; TEIXEIRA, W. G.; FONTANA, A.; BARROS, A. H. C.; VICTORIA, D. de C. 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... ... |
Author(s): CORDEIRO, F. R.; CESÁRIO, F. V.; FONTANA, A.; ANJOS, L. H. C. dos; CANTO, A. C. B. do; TEIXEIRA, W. G. Chemical soil analysis data can be expressed by weight (i.e., gravimetric basis) or volume (i.e., volumetric basis) of the fine earth (sieved >=2 mm), resulting in different units, cmolc kg-1 and cmol... ... |
Author(s): BARROS, A. H. C.; LIER, Q. de J. van; MAIA, A. de H. N.; SCARPARE, F. V. Pedotransfer functions (PTF) were developed to estimate the parameters (a, n, qr and qs) of the van Genuchten model (1980) to describe soil water retention curves. The data came from various sources,... ... |

Author(s): SABINO, B. T. S.; NÓBREGA, C. C. da; SILVA, P. L. F. da; OLIVEIRA, F. P. de; AMARAL, A. J. do Pedotransfer functions are methods proposed with the objective of obtaining indirect information, with greater speed and ease to estimate various soil attributes. Thus, the objective of this work was... ... |
Author(s): BOSCHI, R. S.; BOCCA, F. P.; LOPES-ASSAD, M. L. R. C.; ASSAD, E. D. 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 (MA... ... |
Author(s): OTTONI FILHO, T. B.; OTTONI, M. V.; OLIVEIRA, M. B. de; MACEDO, J. R. de; REICHARDT, K. Levando em conta a natureza dos processos hidrológicos envolvidos na medição da Capacidade de Campo (CC) in situ, este estudo propõe uma variação da definição de CC a fim de minimizar as impropriedade... ... |
