Abstract
Apparatus for determining in-situ the moisture content of potting soil in a plant receptacle. A pair of metallic electrodes are positioned on opposite sides of a plant receptacle adjacent the interior wall thereof and at a distance from the top of the receptacle which corresponds to the normal root depth of a plant to be contained therein. Each electrode extends externally of the receptacle for electrical connection to one probe lead or terminal of a resistance meter. When a plant is potted with soil in the receptacle, the resistance measured between the terminals is related to the moisture content of the potting soil.
