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.

Soil samples were taken from the area immediately surrounding where each penetrometer measurement had been taken (i.
Penetrometer readings were taken as described above at 20 randomly selected sites within the paddock and the 0-150 mm soil was sampled for moisture content only.
We need as much accurate information about the state of the going as we can get and I hope the penetrometer system is introduced
Penetrometer readings are common currency in French racing, but the now defunct Phoenix Park was the only Irish racecourse to make
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.
The `Rimik' penetrometer measures resistance to penetration at 15-mm intervals from the soil surface to a depth of 450 mm, but in this study interpretation was limited to the 90-105 mm and 195-210 mm depths under the furrows and ridges, respectively.
Rimik' recording penetrometer (25-mm-long cone with a total included angle of 30 [degrees] and a diameter of 13 mm; rate of insertion = 15 mm/s; recessed shaft) (ASAE 1986);
Manual soil cone penetrometers are inexpensive and provide quick soil compaction assessments.
More complicated soil cone penetrometers that automatically record pressures and depth are easier for researchers to use.
The result of penetrometer measurements in May 2011 showed that using of alternative tillage (chisel Vederstadt Top Down 600) for five years increased the average soil resistance for 21.
