Evaluation of univariate and multivariate calibration strategies for the direct determination of total carbon in soils by laser-induced breakdown spectroscopy: tutorial. Author(s): GUEDES, W. N.; BABOS, D. V.; COSTA, V. C.; MORAIS, C. P de; FREITAS, V. S.; STENIO, K.; XAVIER, A. A. P.; BORDUCHI, L. C. L.; VILLAS-BOAS, P. R.; MILORI, D. M. B. P. The correct choice of the calibration strategy method is a step that can ensure the accuracy of carbon determination in soils by laser-induced breakdown spectroscopy. In this paper, we evaluate and di... ... Repository: BDPA Publication year: 2023
Tree height and tropical forest biomass estimation. Author(s): HUNTER, M. O.; KELLER, M.; VICTORIA, D. de C.; MORTON, D. C. Tropical forests account for approximately half of above-ground carbon stored in global vegetation. However, uncertainties in tropical forest carbon stocks remain high because it is costly and laborio... ... Repository: BDPA Publication year: 2013
A methodological framework to assess the carbon balance of tropical managed forests. Author(s): PIPONIOT, C.; CABON, A.; DESCROIX, L.; DOURDAIN, A.; MAZZEI, L.; OULIAC, B.; RUTISHAUSER, E.; SIST, P.; HÉRAULT, B. Background: Managed forests are a major component of tropical landscapes. Production forests as designated by national forest services cover up to 400 million ha, i.e. half of the forested area in the... ... Repository: BDPA Publication year: 2016
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
Soil organic carbon determination using NIRS: evaluation of dichromate oxidation and dry combustion analysis as reference methods in multivariate calibration. Author(s): BELTRAME, K. K.; SOUZA, A. M. de; COELHO, M. R.; WINKLER, T. C. B.; SOUZA, W. E.; VALDERRAMA, P. Dichromate oxidation and dry combustion analysis were evaluated as reference methods to determine organic carbon in Brazilian soils using near infrared spectroscopy (NIRS) as an alternative. The main... ... Repository: BDPA Publication year: 2016
Use of data mining techniques to classify soil CO2 emission induced by crop management in sugarcane field. Author(s): FARHATE, C. V. V.; SOUZA, Z. M. de; OLIVEIRA, S. R. de M.; TAVARES, R. L. M.; CARVALHO, J. L. N. Soil CO2 emissions are regarded as one of the largest flows of the global carbon cycle and small changes in their magnitude can have a large effect on the CO2 concentration in the atmosphere. Thus, a... ... Repository: BDPA Publication year: 2018
The Terrestrial Carbon (Terra C) Information System to facilitate carbon synthesis across heterogeneous landscapes. Author(s): HOOVER, B.; GRUNWALD, S.; MARTIN, T. A.; VASQUES, G. M.; KNOX, N. M.; KIM, J.; XIONG, X.; CHAIKAEW, P.; ADEWOPO, J.; CAO, B.; ROSS, C. W. There are urgent needs to better synthesize knowledge and data across large regions and time periods to address global climate change, conduct soil/terrestrial carbon accounting, model carbon dynamics... ...

Carbon stock and dynamics of pioneer and non-pioneer forest species in an undisturbed forest in the Brazilian Amazon. Author(s): SOUZA, C. R.; AZEVEDO, C.; ROSSI, L. B. Repository: BDPA Publication year: 2014
Seasonal variation in tree growth along a hidro-edaphic gradient of oligotrophic forest in northern amazonia. Author(s): CASTILHO, C. V. de; TOLEDO, J. J. Repository: BDPA Publication year: 2016
Influence of the spatial extent and resolution of input data on soil carbon models in Florida, USA. Author(s): VASQUES, G. de M.; GRUNWALD, S.; MYERS, D. B. Understanding the causes of spatial variation of soil carbon (C) has important implications for regional and global C dynamics studies. Soil C predictive models can identify sources of C variation, bu... ... Repository: BDPA Publication year: 2012
