Effect of soil class and moisture on the depth of pupation and pupal viability of Bactrocera carambolae Drew & Hancock (1994). Author(s): AMARAL, E. J. F. do; SOUSA, M. do S. M. de; SANTOS, J. E. V. dos; COSTA, L. M.; MELEM JUNIOR, N. J.; TOLEDO, J. J. de; ADAIME, R. Bactrocera carambolae is a quarantine pest present in Brazil and today represents the main phytosanitary barrier to the export of the fresh fruits produced in the country. The effect of soil classes a... ... Repository: BDPA Publication year: 2021
Multiscale pore-network reconstruction of a fine-textured heterogeneous soil. Author(s): PONTEDEIRO, E. M.; GENUCHTEN, M. Th. van; GODOY, W.; VAZ, C. M. P.; CRESTANA, S.; LIMA, M. C. O.; COUTO, P.; SU, J. Abstract Digital samples offer many opportunities to study subsurface fluid flow and contaminant transport processes. The pore size distribution of especially fine-textured porous media often covers m... ... Repository: BDPA Publication year: 2024
Digital soil mapping at Parque Estadual da Mata Seca, Minas Gerais state, Brazil: applying regression tree to predict soil classes. Author(s): DART, R. de O.; COELHO, M. R.; MENDONÇA-SANTOS, M. de L.; PARES, J. G.; BERBARA, R. L. L. The use of Digital Soil Mapping (DSM) to predict soil classes is an important issue to decrease costs and subjectivity of soil maps. The main objective of this study was to use DSM to produce soil map... ... Repository: BDPA Publication year: 2010
