Pedotransfer functions to estimate water retention parameters of soils in notheastern Brazil. Author(s): BARROS, A. H. C.; MAIA, A. de H. N. 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
Pedotransfer functions to estimate water retention parameters of soils in northeastern Brazil. Author(s): BARROS, A. H. C.; MAIA, A. de H. N. 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
X-ray Microtomography for Investigating Pore Space and Its Relation to Water Retention and Conduction in Highly Weathered Soils. Author(s): VAZ, C. M. P. 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
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... ...

Nonlinear mixed modelling of soil water retention curves. Author(s): MAIA, A. de H. N.; CARVALHO, M. T. de M. Repository: BDPA Publication year: 2014
Coconut residues increase light fraction of organic matter and water retention in semi-arid sandy soil under irrigated cultivation. Author(s): SILVA, I. E. B. da; DEON, M. D. I.; SILVA, D. J.; XAVIER, F. A. da S.; SANTOS, A. P. G.; SIGNOR, D. Coconut palm cultivation is associated with the generation of a large amount of residues, mainly from coconut shells, and their utilization in agriculture can represent an opportunity in the context o... ...

Water retention capacity in Arenosols and Ferralsols in a semiarid area in the state of Bahia, Brazil. Author(s): PARAHYBA, R. da B. V. 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... ...

How to predict soil water holding capacity using physically based equations? Author(s): TEIXEIRA, W. The soil surface and porosity govern the capacity of soil to hold water. In soil science, many functions were developed to estimate parameters of equations to describe soil water retention and soil hy... ... Repository: BDPA Publication year: 2014
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
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... ...
