A STUDY ON A COMBINED HORIZONTAL PENETROMETER FOR SIMUTANIOUS MEASUREMENT OF SOIL WATER CONTENT AND MECHANICAL RESISTANCE

摘要：

A combined horizontal penetrometer was designed for the on-the-go and simultaneous measurement of soil water content and mechanical resistance. For the water content sensor, its measurement principle depends on the electric field of the fringe capacitance. In order to evaluate the applicability of this combined penetrometer, two experiments in the field were carried out. One is the soil water content profiles test, and the other is soil compaction measurement test. The experimental results show that the combined horizontal penetrometer is a practical tool since it can provide more useful information of soil physical properties.
