Truncated beta nonlinear regression models for soil-water characteristic curves estimation. Author(s): PARAÍBA, C. C. M.; DINIZ, C. A. R.; MAIA, A. de H. N.; RODRIGUES, L. N. We propose an alternative approach for estimating soil-water characteristic curves based on truncated beta nonlinear regression models. Thus, assuming that the response variable follows a truncated be... ... Repository: BDPA Publication year: 2013
Truncated normal nonlinear regression models for soil-water characteristic curves. Author(s): PARAÍBA, C. C. M.; DINIZ, C. A. R.; MAIA, A. de H. N.; RODRIGUES, L. N. Repository: BDPA Publication year: 2012
Fitting soil-water characteristic curves by truncated normal nonlinear regression models. Author(s): PARAÍBA, C. C. M.; DINIZ, C. A. R.; MAIA, A. de H. N.; RODRIGUES, L. N. Repository: BDPA Publication year: 2013
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
X-ray Microtomography for Investigating Pore Space and Its Relation to Water Retention and Conduction in Highly Weathered Soils. Author(s): PESSOA, T. N.; FERREIRA, T. R.; PIRES, L. F.; COOPER, M.; UTEAU, D.; PETH, S.; VAZ, C. M. P.; LIBARDI, P. L. Abstract: Soil structure controls soil hydraulic properties and is linked to soil aggregation processes. The aggregation processes of Oxisols are controlled mainly by clay mineralogy and biological ac... ... Repository: BDPA Publication year: 2023
Water retention capacity in Arenosols and Ferralsols in a semiarid area in the state of Bahia, Brazil. Author(s): PARAHYBA, R. da B. V.; ARAÚJO, M. do S. B. de; ALMEIDA, B. G. de; ROLIM NETO, F. C.; SAMPAIO, E. V. S. B.; CALDAS, A. M. One of the most serious problems in areas indicated for irrigation projects in the Brazilian Northeast region is the occurrence of sandy soils, known to have low moisture retention, but occurring in s... ...

Monitoramento da umidade do solo por meio da reflectância hiperespectral de folhas de soja. Author(s): CRUSIOL, L. G. T.; NANNI, M. R.; SIBALDELLI, R. N. R.; FURLANETTO, R. H.; GONCALVES, S. L.; FOLONI, J. S. S.; MERTZ-HENNING, L. M.; NEPOMUCENO, A. L.; NEUMAIER, N.; FARIAS, J. R. B. Repository: BDPA Publication year: 2022
Alterações nas propriedades físicas de um Latossolo Amarelo Distrocoeso em função da aplicação de carvão vegetal. Author(s): BRITO, R. B. F.; SOUZA, L. D.; SOUZA, L. da S. A necessidade de adequação dos sistemas de produção agrícola tem estimulado a busca de novos manejos do solo. A evolução tem procurado uma maior capacidade para diminuir a emissão e aumentar a convers... ... Repository: BDPA Publication year: 2013
Nonlinear mixed modelling of soil water retention curves. Author(s): MAIA, A. de H. N.; CARVALHO, M. T. de M.; BASTIAANS, L.; VAN OORT, P. A. J.; MEINKE, H. Repository: BDPA Publication year: 2014
Development stages of furrow-irrigated rice and their relationship with estimates from the App PlanejArroz. Author(s): STEINMETZ, S.; PARFITT, J. M. B.; SCIVITTARO, W. B.; THEISEN, G.; DIAS, L. de S.; MARTIN, J. G. Abstract: The objectives of this study were to characterize how the water regime and the furrow and ridge environments affect the plant development stages (PDS) and how these stages relate to estimate... ...
