The portable nature of the Series 100 Rotational Penetrometer makes it the only quantifiable solution to confirm firmness and stability of existing surfaces in outdoor recreation areas.

At each sampling in each field, 10 penetrometer (Rimik Agricultural Electronics CP20 Cone Penetrometer) readings were taken to a depth of 600 mm at random locations along a defined transect in each field.
Soil samples were taken from the area immediately surrounding where each penetrometer measurement had been taken (i.
Previous research with MoSCSSS has shown a correlation of improved stalk lodging resistance and increased rind
penetrometer resistance.
Osborne said: "The
penetrometer used to take the measurements was a slight modification of the version used in France.
Finally, changes in
penetrometer data between sampling dates was not reflected by differences in bulk density and saturated hydraulic conductivity.
Correlations between the shear vane and the
penetrometer were investigated so that root growth critical limits from the literature, expressed in terms of penetration resistance, can be converted, if required, for use with the shear vane.
Manual soil cone
penetrometers are inexpensive and provide quick soil compaction assessments.
For measuring soil horizontal resistance a horizontal
penetrometer was used (Fig.
The objectives of this study were to (i) locate QTL for rind
penetrometer resistance in four maize populations, (ii) estimate their effects, and (iii) identify candidate genes for these QTL.
Selected phenotypic correlation coefficients among rind
penetrometer resistance (RPR), plant height (PH), ear height (EH), and rind
penetrometer resistance adjusted for ear height (RadjE) in all populations: Population 1, (MoSCSSS-High1 x MoSQB-Low)[F.
