Development and uncertainty assessment of pedotransfer functions for predicting water contents at specific pressure heads. 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... ...

Pedotransfer functions to estimate water retention parameters of soils in notheastern Brazil. 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,... ... Repository: BDPA Publication year: 2013
Evaluation of hydrocyclone as pre-filter in irrigation system. Author(s): SOCCOL, O. J.; RODRIGUES, L. N.; BOTREL, T. A.; ULLMANN, M. N. The objective of this work was to evaluate the efficiency of a hydrocyclone to separate sand in irrigation water. To do this, it an experiment was conducted where the hydrocyclone was operated with pr... ... Repository: BDPA Publication year: 2007
Predicting coffee water potential from spectral reflectance indices with neural networks. Author(s): NUNES, P. H.; PIERANGELI, E. V.; SANTOS, M. O.; SILVEIRA, H. R. O.; MATOS, C. S. M. de; PEREIRA, A. B.; ALVES, H. M. R.; VOLPATO, M. M. L.; SILVA, V. A.; FERREIRA, D. D. Leaf water potential is one of the main parameters used to assess water relations in plants by revealing levels of tissue hydration. It is commonly measured with the Scholander pressure chamber; which... ... Repository: BDPA Publication year: 2023
Leaching runoff fraction for nitrate and herbicides on sugarcane fields: implications for grey water footprint. Author(s): SCARPARE, F. V.; ZOTELLI, L. do C.; BARIZON, R. R. M.; CASTRO, S. G. Q. de; BEZERRA, A. H. F. Abstract: Sugarcane cultivation uses many chemical inputs to ensure good yields, which puts local water resources under pressure. Grey water footprint (GWF) is a widely used indicator of the volume ne... ... Repository: BDPA Publication year: 2023
