Espaçamento do grid e número de subamostras na coleta de solo com agricultura de precisão
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilManejo da Fertilidade do SoloUTFPR, 2016-12-19)
The objective of the present work was to evaluate the spacing of the sampling grid and number of subsamples in the quality of the soil collection in an area under precision agriculture. The work was carried out in the ...
Computing transient voltages on grounding grids buried in homogeneous and stratified soils
(2020-09-28)
Grounding grids (GGs) are essential to guarantee protection to personnel and equipment in the electrical substation. In this context, GGs provide low impedance path to high currents during faults or lightning strikes to ...
Malhas de amostragem retangular e hexagonal na geração de mapas de fertilidade e aplicação para agricultura de precisão
(Universidade Federal de Santa MariaBRTecnologia em Agricultura de PrecisãoUFSMPrograma de Pós-Graduação em Agricultura de Precisão, 2016-09-15)
Sample grid s are essential when we want to represent the variation in chemical and physical properties of the soil, being essential to know its features. In this way, this study aimed to relate the efficiency and practicality ...
The spatial variability structure of soil attributes using a detailed sampling grid in a typical periglacial area of Maritime Antarctica
(Environmental Earth Sciences, 2018)
Variabilidade espacial de perdas de solo, do potencial natural e risco de erosão em áreas intensamente cultivadas
(2006-04-01)
The objective of this work was to identify the spatial variability of the natural erosion potential, soil loss and erosion risk in two intensely cultivated areas, in order to assess the erosion occurrence patterns. The ...

Comparative analysis of soil-sampling methods used in precision agriculture
(Italian Society of Agricultural Engineering, 2022)
Computation of Surge Voltage in Transmission Tower Located above Frequency-Dependent Soil
(2021-01-01)
The purpose of this paper is to investigate the influence of frequency-dependent soils with variable soil content on the transient voltages at transmission towers. First, a comparative analysis between the impedance of ...
A new approach to soil classification mapping based on the spatial distribution of soil properties
(Elsevier B.V., 2014-05-01)
This study presents a new approach to classifying types of soil based on the probability classes of the relevant set of attributes. Two key ideas are addressed in this study: (i) the use of stochastic simulations to generate ...
Spatial and temporal variability in soil CO2-C emissions and relation to soil temperature at King George Island, maritime Antarctica
(2010-12-01)
Few studies have examined the effects of temperature on spatial and temporal trends in soil CO2-C emissions in Antarctica. In this work, we present in situ measurements of CO2-C emissions and assess their relation with ...
