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
Determination of soil pore size distribution and water retention curve by internal magnetic field modulation at low field 1H NMR. Author(s): NOVOTNY, E. H.; AZEVEDO, E. R. de; GODOY, G. de; CONSALTER, D. M.; COOPER, M. The determination of the soil pore size distribution, water retention curve, and derived parameters that control important processes in soils, such as water supply for plants; infiltration; water and... ...

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... ...

Pedotransfer functions to estimate water retention parameters of soils in northeastern Brazil. Author(s): BARROS, A. H. C.; JONG VAN LIER, Q. de; MAIA, A. de H. N.; SCARPARE, F. V. Abstract: Pedotransfer functions (PTF) were developed to estimate the parameters of the van Genuchten model (1980) to describe soil water retention curves. The data came from various sources, mainly f... ... Repository: BDPA Publication year: 2013
Biochar increases plant-available water in a sandy loam soil under an aerobic rice crop system. Author(s): CARVALHO, M. T. de M.; MAIA, A. de H. N.; MADARI, B. E.; BASTIAANS, L.; VAN OORT, P. A. J.; HEINEMANN, A. B.; SILVA, M. A. S. da; PETTER, F. A.; MARIMON JUNIOR, B. H.; MEINKE, H. The main objective of this study was to assess the impact of biochar rate (0, 8, 16 and 32 Mg ha-1) on the water retention capacity (WRC) of a sandy loam Dystric Plinthosol. The applied biochar was a... ... Repository: BDPA Publication year: 2014
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
A utilização do carvão vegetal como condicionador de solos. Author(s): PAZ, E. J. de J. da; SOUZA, L. D. A terra preta do Índio (TPI) surgiu a partir de ações antrópicas. Evidências provam que esses solos foram formados por antigas comunidades indígenas amazônicas, que habitavam áreas densamente povoadas... ... Repository: BDPA Publication year: 2013
