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
Soil texture classification by Mid-infrared spectroscopy (MIR). Author(s): MORAIS, P. A. O.; SOUZA, D. M.; MADARI, B. E.; CARVALHO, M. T. M. O objetivo deste trabalho é propor uma metodologia de classificação textural através de MIR e do método de calibração multivariado máquinas de vetores de suporte por mínimos quadrados.

Phosphorus adsorption capacity in sandy textured soils with built fertility. Author(s): FONTANA, A.; PEREIRA, M. G.; SANTOS, J. J. S. dos; DONAGEMMA, G. K.; SANTOS, O. A. Q. dos The specific adsorption of phosphorus in minerals from the clay fraction of the soil, such as Fe and Al oxyhydroxides, is responsible for the decrease in the availability of this element for plants. I... ... Repository: BDPA Publication year: 2021
Nodulation, gas exchanges and production of peanut cultivated with Bradyrhizobium in soils with different textures. Author(s): MELO, E. B. S. de; LIMA, L. M. de; FERNANDES JUNIOR, P. I.; AIDAR, S. de T.; FREIRE, M. A. O.; FREIRE, R. M. M.; SANTOS, R. C. dos Nitrogen fertilization from biological source is an uncommon practice for peanut growers due to the limited results, mainly in environments with water restriction. In this study, the response of a com... ... Repository: BDPA Publication year: 2016
Carbon stocks and pools in relation to the texture of kaolinitic soils from the Brazilian East Coast. Author(s): GOMES, J. B. V.; SILVA, C. A.; FERREIRA, T. L. de A.; FERREIRA, M. M.; INDA, A. V.; CURI, N. Extremely kaolinitic soils of Tertiary age elevations on the Brazilian east coast present a wide range of texture, which is recognized as one of the main factors controlling the soil organic matter co... ...

Genesis of textural contrasts in subsurface soil horizons in the northern Pantanal-Brazil. Author(s): NASCIMENTO, A. F. do; FURQUIM, S. A. C.; COUTO, E. G.; BEIRIGO, R. M.; OLIVEIRA JUNIOR, J. C. de O.; CAMARGO, P. B. de; VIDAL-TORRADO, P. O Pantanal caracteriza-se por ser uma planície inundável quaternária, com sedimentação predominantemente na forma de leques aluviais. Na evolução geomorfológica e sedimentar, é inerente a esse sistema... ... Repository: BDPA Publication year: 2013
Influence of irrigation and soil texture in the growth of peach tree branches and fruits of cv. Esmeralda. Author(s): MONTEIRO, A. B.; TIMM, L. C.; REISSER JUNIOR, C.; ROMANO, L. R.; TOEBE, M. Repository: BDPA Publication year: 2019
