Assessment of sugarcane harvesting residue effects on soil spectral behavior
(Univ Sao Paolo, 2016-03-01)
When the harvesting of sugarcane involves a mechanized process, plant residues remain on the soil surface, which makes proximal and remote sensing difficult to monitor. This study aimed to evaluate, under laboratory ...
Alteration of soil properties through a weathering sequence as evaluated by spectral reflectance
(1999-03-01)
In the study of physical, chemical, and mineralogical data related to the weathering of soils and the quantification of their properties, remote sensing constitutes an important technique that, in addition to conventional ...

Multi-temporal satellite images on topsoil attribute quantification and the relationship with soil classes and geology
(2018-10-01)
The mapping of soil attributes provides support to agricultural planning and land use monitoring, which consequently aids the improvement of soil quality and food production. Landsat 5 Thematic Mapper (TM) images are often ...
Spectroradiometry of soil and comparison with orbital sensors
(INST AGRONOMICOCAMPINAS, 2012)
The aim of this study was to characterize and compare the spectral behavior of different soil classes obtained by orbital and terrestrial sensors. For this, an area of 184 ha in Rafard (SP) Brazil was staked on a regular ...
A method for soil moisture probes calibration and validation of satellite estimates
(Elsevier Science, 2017-07)
Optimization of field techniques is crucial to ensure high quality soil moisture data. The aim of the work is to present a sampling method for undisturbed soil and soil water content to calibrated soil moisture probes, in ...
