Spatial variability of soil water content and mechanical resistance of Brazilian ferralsol
(Elsevier B.V., 2006-01-01)
The spatial variability of mechanical resistance to penetration (PR) and gravimetric moisture (GM) was studied at a depth of 0-0.40 m, in a ferralsol cropped with corn, and under conventional tillage in llha Solteira, ...

An empirical model to predict soil bulk density profiles in field conditions using penetration resistance, moisture content and soil depth
(Elsevier, 2000-10)
Cylindrical soil probes measuring 300 mm in diameter by 300 mm in height were prepared in the laboratory using samples extracted from a well drained loamy soil (FAO classification: Vertic Luvisol). These probes were compacted ...
Assessing the soil physical characteristics of the gallery woods area at the hydrographic Mariana sub-catchment for environmental conservation
(2013-01-01)
The objective of this work was to characterize soil physical properties of the gallery woods area at the hydrographic Mariana sub-catchment. The physical attributes evaluated were: bulk density, gravimetric humidity, soil ...
Specific depth cone resistivity measurements to determine soil engineering properties
(2003-03-01)
The University of British Columbia (UBC) began performing piezocone penetration tests (CPTU) with electrical resistivity measurements (RCPTU) in 1989. Since then, RCPTU research at UBC has focused on obtaining geo-environmental ...

Atributos físicos de latossolo vermelho sob pousio ou cultivado com forrageiras tropicais sob pastejo
(2012-04-26)
The objective was to study the physical attributes of an Oxisol under fallow or planted with tropical grasses under grazing. The experiment was conducted under the experimental design of randomized blocks in split-plot 2 ...
Estimación de la densidad volumétrica y porosidad total usando el penetrómetro
(2018)
Las mediciones de densidad volumétrica y porosidad total están altamente correlacionadas con valores de resistencia a la penetración. El objetivo del presente estudio fue determinar las ecuaciones de regresión que permiten ...
