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
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
Predicting the nutritional value of tropical forages by Near Infrared Reflectance Spectroscopy (NIRS). Abstract – The aim was to improve multivariate calibration curves for near- infrared refl ectance spectroscopy (NIRS) for the measurement and prediction of nutritive value of tropical forages. Samples... ... Repository: BDPA Publication year: 2024
Near-infrared reflectance spectroscopy as a tool for breeding Andropogon gayanusKunth for forage quality. Abstract: The objective was to investigate the usefulness of Near Infrared Spectroscopy (NIRS) to predict bromatological traits concentrations of gamba grass (Andropogon gayanus Kunth). Random samples... ... Repository: BDPA Publication year: 2020
Visible and near infrared reflectance spectroscopy (Vis-NIRS) to predict tenderness in Nellore cattle. Repository: BDPA Publication year: 2013
Predicting the oil contents in sunflower genotype seeds using near-infrared reflectance (NIR) spectroscopy. ABSTRACT: The aim of this experiment was to calibrate the NIR spectroscopy equation to evaluate the oil content of sunflower seeds from different genotypes produced under different environmental condi... ... Repository: BDPA Publication year: 2014
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
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... ... Repository: BDPA Publication year: 2022
Visible and near infrared spectra of Ferralsols according to their structural features. ABSTRACT: In soil science, structural features of soils are an important attribute; soils can be characterised by proportional size distribution of aggregates and the pore space between and within tho... ... Repository: BDPA Publication year: 2016
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,... ...
