TL;DR: The Brazilian Soil Spectral Library (BSSL) as mentioned in this paper was developed in a joint partnership with the Brazilian pedometrics community to standardize and evaluate spectra within the 350-2500nm range of Brazilian soils.
Journal ArticleDOI
Satellite Spectral Data on the Quantification of Soil Particle Size from Different Geographic Regions
José Alexandre Melo Demattê,Clécia Cristina Barbosa Guimarães,Caio Troula Fongaro,Emmily Larissa Felipe Vidoy,Veridiana Maria Sayão,André Carnieletto Dotto,Natasha Valadares dos Santos +6 more
TL;DR: In this article, the authors developed a quantification model for soil mapping using remote sensing (RS) techniques, which can be used to provide spatial information for agricultural management, including physical and chemical properties of the soil.
Journal ArticleDOI

TL;DR: In this article, the potential use of spectroscopy in the visible (Vis), near infrared (NIR) and mid-infrared (MIR) regions and their combination to estimate total carbon and nitrogen stocks are evaluated using seven different pre-processing and two regression models and comparing to the concentrations determined by dry combustion of 701 soil samples from different soil classes and land uses in Northeast Brazil.
