Safanelli, José Lucas; Demattê, José Alexandre Melo; Santos, Natasha Valadares dos; Rosas, Jorge Tadeu Fim; Silvero, Nélida Elizabet QuiñonezMultitemporal collections of satellite images and their products have recently been explored in digital soil mapping. This study aimed to produce a bare soil image (BSI) for the São Paulo State (Brazil) to perform a pedometric analysis for different geographical levels. First, we assessed the potential of the BSI for predicting the surface (0.00-0.20 m) and subsurface (0.80-1.00 m) clay, iron oxides (Fe 2 O 3 )...

Fernandes Filho, Elpídio Inácio; Campbell, Patrícia Morais da Matta; Francelino, Márcio Rocha; Demattê, José Alexandre Melo; Pereira, Marcos GervasioQuantification of soil properties is essential for better understanding of the environment and better soil management. The conventional techniques of laboratory analysis are sometimes costly and detrimental to the environment. Thus, development of new techniques for soil analysis that do not generate residues, such as spectroscopy, is increasingly necessary as a viable way to estimate a wide range of soil prope...
