New tools for soil mapping are needed to increase speed and accuracy of pedological mapping processes. This study integrated various technologies to map soils of the Piracicaba region in São Paulo State, Brazil. Each technology was expected to provide different information to design a detailed map. We carried out field survey and soil sampling for laboratory analysis. Initially, we conducted fi...
The expansion of agricultural activities in Brazil resulted a loss approximately 50% the native vegetation Cerrado biome, mainly to north biome region known as MATOPIBA. Besides contributing accelerate climate change, removal is associated with increase soil degradation. In this study, we used decision tree method predict degradation using indicators Normalized Difference Vegetation Index (NDVI...
Digital terrain models (DTM) have been used in soil mapping worldwide. When using such models, improved predictions are often attained with the input of extra variables provided by the use of proximal sensors, such as magnetometers and portable X-ray fluorescence scanners (pXRF). This work aimed to evaluate the efficiency of such tools for mapping soil classes and properties in tropical conditi...
