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 ...
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 ...

Spatial variability of forage yield and soil physical attributes of a Brachiaria decumbens pasture in the Brazilian Cerrado
(Sociedade Brasileira de Zootecnia, 2011-10-01)
The objective of this study was to analyze variability, linear and spatial correlations of forage dry mass yield (FDM) and dry matter percentage (DM%) of Brachiaria decumbens with the bulk density (BD), gravimetric (GM) ...
