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
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
Uso de informações de solo no zoneamento agrícola de risco climático. Author(s): LOPES-ASSAD, M. L.; BOSCHI, R. S.; NOMURA, E.; EVANGELISTA, B. A.; SILVA, J. dos S. V. da O objetivo desse trabalho é apresentar os critérios para a reclassificação de solos, a partir de levantamento de baixa intensidade, considerando a estimativa da capacidade de água disponível.

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
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
