    Abstract

    A combined dynamic cone penetrometer and capacitive soil moisture meter is reported. A novel electrode configuration utilizing a shield electrode increases the effective measurement diameter. A readout circuit is implemented that is relatively insensitive to the resistivity of water in soil. The moisture meter electronics fit within a rugged stainless steel pipe with a wall thickness of 1/8 in. and an outer diameter of 0.75 in.
