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.
Claims9
A plant receptacle for measuring the moisture content of the soil adapted to be contained therein, comprising two spaced metallic electrodes on the interior wall of said receptacle positioned at a depth in said receptacle commensurate with the normal root level of a plant adapted to be potted in said soil, and metallic terminals on the exterior of said receptacle electrically connected to said electrodes, and means coupled to said metallic terminals for indicating the moisture content of said soil at said root level of said plant.
