Reference indicated that for accurate assessment of changes in the soil fabric due to compaction, measurement of bulk density is not adequate. penetration resistance is frequently used in the assessment of surface strength in association with bulk density.Reference indicated that PR is regarded as a useful measure of soil impedance and root growth.Although penetration resistance determination is relatively rapid compared to bulk density, both applications are limited at extremes of moisture content where high and low soil strength interferes with point measurements, and bulk sampling respectively.Reference [2] illustrated the bell shaped response for these two parameters with increasing water content.
