ESTIMATIVA DOS TEORES DE CARBONO POR ESPECTROSCOPIA NO INFRAVERMELHO EM Merostachys skvortzovii (BAMBUSOIDAE)

Abstract: ResumoOs métodos para a estimação do carbono no solo e na vegetação são críticos para as estimativas, geralmente são onerosos e envolvem muito trabalho de campo e de laboratório. Essa justificativa reforça a necessidade de uma metodologia rápida e de simples operação e resposta. Dessa forma, o objetivo deste trabalho é validar a utilização do infravermelho para gerar estimativas que possam satisfazer as premissas de rapidez e baixo custo nas estimativas com alta correlação aos teores reais de carbono encontrad… Show more

“…Silva et al [25], in a study on the characterization of the energy properties of tropical wood residues, observed R 2 of 0.93 for fixed carbon in the wood in the calibration and 0.85 in the validation between the traditional method and the NIR method, with RPD of 1.8 characterized as acceptable. Dallagnol et al [26], who tested the potential for predicting carbon content by NIR for the species Merostachys skvortzovii, found correlation coefficients in both calibration (R 2 = 0.822) and validation (R 2 = 0.764) that are below those observed in the present study. This fact shows that the established model is adequate to replace traditional methods with NIR in the estimation of carbon, ash and dry matter contents in C. spruceanum.…”

“…Esse procedimento é ainda mais complexo, requerendo software específico, porque a operação matemática resultante não é óbvia. Suga et al (2011) (SILVA et al, 2009;MENDES et al, 2010;DALLAGNOL et al, 2013). Mesmo em nível internacional os trabalhos de modelagem são bastante restritos.…”
