ABSTRACT:
Method and apparatus for measuring the water status of a plant by measuring the long term variations in biological electrical potential developed by the plant. The electrical potential developed by the plant is measured by placing a first electrical probe in the root environment of the plant and a second electrical probe in the body of the plant and measuring the electrical potential between the probes with an electrometer or a high impedance voltmeter. The measured potential is amplified and displayed to provide an indication of the combined water status of the plant and its root environment. Several plants or several points on a single plant may be monitored over a period of time ranging from a few days to several months by utilizing a plurality of probes and sequentially measuring the potential developed between predetermined various ones of the probes.
