Combination cone penetration resistance/water content instrumentation to evaluate cone penetration–water content relationships in tillage research

Cone penetration resistance (PR) is generally regarded as one of the best tools to assess soil strength. However, effects of soil water content (WC) on measured PR can mask or confound interpretations of treatment effects on soil strength. Correction of PR data to common water contents, via empirica...
