Soil Moisture Monitoring
- Tensiometers: Utilize a vacuum gauge to measure soil water tension, providing an indirect measure of soil moisture content. - Soil Moisture Sensors: Utilize electrical resistance or capacitance to directly measure soil moisture content. - Neutron Probes: Employ radioactive sources to measure soil water content by detecting the attenuation of neutrons.Plant Moisture Monitoring
- Stem Water Potential Sensors: Measure water pressure within plant stems, indicating plant water status. - Leaf Water Potential Sensors: Measure water pressure within plant leaves, providing a direct measure of plant water status. - Infrared Thermometers: Detect differences in temperature between plant leaves and the surrounding air, reflecting plant water stress.
