Abstract. Geophysical sensors combined with machine learning algorithms were used to understand the pedosphere system and landscape processes model soil attributes. In this research, we parent material, terrain attributes, data from geophysical in different combinations test compare novel We also analyzed importance of pedoenvironmental variables predictive models. For that, collected physicochemical (gamma-ray emission uranium, thorium, potassium; magnetic susceptibility apparent electric...
Soil apparent electrical conductivity (ECa) is related to various soil attributes and processes. This research aimed understand the relationship between ECa paedogenesis, lithology attributes. The study area located in São Paulo State, Brazil. samples were collected for physical-chemical analysis from 79 locations (0–20 cm layer). A geophysical field-portable equipment (Geonics EM38-MK2 meter) was used measure ECa. For that, four toposequences selected on landscape. Sixteen profiles...
Diante da atual situação de Pandemia declarada pela Organização Mundial Saúde, em março 2020, decorrente dispersão rápida do Coronavírus, cuja doença principal – a COVID-19 pode causar superlotação dos serviços públicos saúde e acentuar as perdas vida população, surgem questionamentos relativos ao quão vulnerável os territórios estão relação esse fenômeno perigosidade, e, para além disso, qual o grau risco que populações expostas, considerando características territórios. Nesse sentido,...

Abstract. Weathering is widely used for pedogenesis and soil fertility studies, once it affects several attributes. Understanding the intensities of weathering can provide answers environmental issues, geosciences studies. Recently, there are available geotechnologies (such as geophysics machine learning algorithms) that be applied in science to pedosphere information. In this research, we performed a method evaluate intensity heterogeneous tropical area by proximal remote sensing data...

Geophysical techniques applied to soils and machine learning algorithms have been used understand the dynamics of pedosphere model soil attributes, but studies exploring spatial prediction geophysical data are still scarce. In this research, we aimed map attributes using parent material terrain with different algorithms. addition, tested nested leave-one-out cross validation (nested-LOOCV) methodology deal datasets a small number samples. We collected physico-chemical (gamma-ray emission...
