Prediction of soil physical and chemical properties by visible and near-infrared diffuse reflectance spectroscopy in the Central Amazon. Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physic... ... Repository: BDPA Publication year: 2017
Qualitative evaluation of soil organic matter using Vis-NIR diffuse reflectance spectroscopy in an agroecological production system in Seropédica, Rio de Janeiro (Brazil). The aim of this study was to compare SOM contents and associated Vis-NIR spectral curves among areas with different agroecological production systems/treatments. Repository: BDPA Publication year: 2019
Pedometric tools for classification of southwestern Amazonian soils: a quali-quantitative interpretation incorporating visible-near infrared spectroscopy. The southwestern region of the Amazon has great environmental variability, presents a great complexity of pedoenvironments due to its rich variability of geological and geomorphological environments,... ...

Soil classification from visible/near-infrared diffuse reflectance spectra at multiple depths. Abstract : Visible/near-infrared diffuse reflectance spectroscopy (VNIRS) offers an alternative to conventional analytical methods to estimate various soil attributes. However, the use of VNIRS in soi... ... Repository: BDPA Publication year: 2011
Leaf Spectra Changes of Plants Grown in Soils Pre- and Post-Contaminated with Petroleum Hydrocarbons. ABSTRACT: Leaks from accidents or damage to pipelines that transport liquid petroleum hydrocarbons (PHC) such as gasoline and diesel are harmful to the environment as well as to human health, and may... ...

Identification of mineral components in tropical soils using reflectance spectroscopy and advanced spaceborne thermal emission and reflection radiometer (ASTER) data. Soil characteristics provide important support for understanding transformations that occur in environmental systems. Physical characteristics and chemical compositions of soils controlled by pedogene... ... Repository: BDPA Publication year: 2011
Brachiaria plantaginea as a potential (new) source of shikimic acid: quantification by NIR and PLS regression. Abstract: Shikimic acid is a natural organic compound produced in the biochemical pathways of eukaryotic organisms and is generally utilized as a starting material of the antiviral drug Oseltamivir (T... ...

Espectrometria de infravermelho próximo na predição da textura de solos desenvolvidos de basalto. A textura dos solos tem sido determinada através de métodos analíticos que muitas vezes são caros e lentos. Ademais, em solos muito argilosos, a dispersão química e mecânica nem sempre é eficiente em... ... Repository: BDPA Publication year: 2014
Predição da composição bromatológica de palma forrageira por meio da espectroscopia de reflectância no infravermelho próximo (NIRS). Resumo: A espectroscopia de reflectância na região do infravermelho próximo (NIRS) é uma ferramenta alternativa aos métodos convencionais para determinar a qualidade de dietas. Objetivou-se com este t... ... Repository: BDPA Publication year: 2017
