Monitoring pasture aboveground biomass and canopy height in an integrated crop-livestock system using textural information from PlanetScope imagery. Author(s): REIS, A. A. dos; WERNER, J. P. S.; SILVA, B. C.; FIGUEIREDO, G. K. D. A.; ANTUNES, J. F. G.; ESQUERDO, J. C. D. M.; COUTINHO, A. C.; LAMPARELLI, R. A. C.; ROCHA, J. V.; MAGALHÃES, P. S. G. Abstract: Fast and accurate quantification of the available pasture biomass is essential to support grazing management decisions in intensively managed fields. The increasing temporal and spatial reso... ... Repository: BDPA Publication year: 2020
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
Physical and chemical matrix effects in soil carbon quantification using laser-induced breakdown spectroscopy. Author(s): SEGNINI, A.; XAVIER, A. A. P.; OTAVIANI JÚNIOR, P. L.; FERREIRA, E. C.; WATANABE, A. M.; SPERANÇA, M. A.; NICOLODELLI, G.; VILLAS-BOAS, P. R.; OLIVEIRA, P. P. A.; MILORI, D. M. B. P. Advanced field methods of carbon (C) analysis should now be capable of providing repetitive, sequential measurements for the evaluation of spatial and temporal variation at a scale that was previously... ...

Hierarchical pedotransfer functions for predicting bulk density in Brazilian soils. Author(s): REIS, A. M. H. dos; TEIXEIRA, W. G.; FONTANA, A.; BARROS, A. H. C.; VICTORIA, D. de C.; VASQUES, G. M.; SAMUEL-ROSA, A.; OTTONI, M. V.; MONTEIRO, J. E. B. de A. Bulk density (BD) is a soil physical property used as a soil quality indicator and variations in this measurement influence soil water content and carbon stock estimates. This study aims to compile a... ... Repository: BDPA Publication year: 2024
Preliminary measurements on diel CH4 and N2O fluxes on Brachiaria pasture. Author(s): LIMA, M. A. de; LUIZ, A. J. B.; GALVAO, J. A. H.; CABRAL, O. M. R. Brazil has extensive pasture areas for beef cattle grazing. An experiment was carried out in summer in a Brachiaria pasture in Southeastern Brazil, characterized by hot and humid climate in summer and... ... Repository: BDPA Publication year: 2022
