Prediction and mapping of soil attributes using diffuse reflectance spectroscopy and magnetic susceptibility
(2017-11-01)
The development of fast, accurate and low-cost methods to quantify soil attributes is of paramount importance to enable detailed mapping, mainly in tropical regions where there is great variation of the chemical, physical ...
Soil type spatial prediction from Random Forest: different training datasets, transferability, accuracy and uncertainty assessment
(Escola Superior de Agricultura "Luiz de Queiroz", 2020)
Multivariate mapping of soil with structural equation modelling
(2017-09)
In a previous study we introduced structural equation modelling (SEM) for digital soil mapping in the Argentine Pampas. An attractive property of SEM is that it incorporates pedological knowledge explicitly through a ...
Sampling scheme optimization to map soil depth to petrocalcic horizon at field scale
(2017-03-15)
Soil depth has played a key role in the development of soil survey, implementation of soil-specific management and validation of hydrological models. Generally, soil depth at field scale is difficult to map due to complex ...
Mapeamento digital de solos por meio de índices de relevo na Bacia Hidrográfica do Rio do Lontra, PR
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilCurso de Engenharia FlorestalUTFPR, 2017-06-08)
Soil maps with high level of detail and precision, both for Brasil and the state of Parana, are scarce due to the high cost, time and trained technicians to make them, resulting in a lack of information about this natural ...
Multivariate split moving windows and magnetic susceptibility for locating soil boundaries of São Paulo, Brazil
(2021-09-01)
Multivariate split moving window (MSMW) is a tool to automate soil mapping and to assess uncertainty in soil boundaries. In this paper, we propose a new approach to locate soil boundaries. We investigated the potential of ...
Soil erodibility mapping and its correlation with soil properties in Central Chile
(ELSEVIER SCIENCE BV, 2012)
In the Revised Universal Soil Loss Equation (RUSLE), erodibility accounts for the influence of soil properties on soil loss during storm events in upland areas, which is represented by the soil erodibility factor (K). ...
Prediction and spatial variability of soil dynamic properties in sugar cane fields of São Paulo State Brazil
(Wageningen Academic Publishers, 2005-01-01)
The objective of this work was to model and diagnose the spatial variability of soil load support capacity (SLSC) in sugar cane crop fields, as well as to evaluate the management impact on São Paulo State soil structure. ...
