Moisture Mapping Soil and Plant Moisture Monitoring

Tensiometers: Measure the soil water tension, providing insights into the water availability for plants.
Soil Moisture Sensors: Embedded in the soil to directly measure moisture content volumetrically or gravimetrically.
Neutron Probes: Utilize neutron scattering to determine moisture content over a larger soil volume.
Time Domain Reflectometry (TDR): Measure soil moisture by sending electromagnetic pulses through the soil and analyzing the reflected signal.
Subsurface Drip Irrigation (SDI) Systems: Equipped with sensors that monitor soil moisture and automatically adjust irrigation schedules accordingly.

Determining plant moisture levels aids in optimizing irrigation and maintaining plant health.

Pressure Chamber: Measures the water potential of plant leaves, indicating their hydration status.
Leaf Water Potential Psychrometer: Similar to the pressure chamber, but uses a psychrometer to determine leaf water potential.
Stem Water Potential Psychrometer: Measures water potential in plant stems, providing an assessment of plant hydration.
Infrared Thermometry: Utilizes infrared sensors to measure leaf temperature, with higher temperatures indicating moisture stress.
Spectral Reflectance: Analyzes the spectral reflectance of plant leaves using remote sensing techniques, providing insights into plant water status.
