Eddy Covariance System in the Field

Eddy covariance system is also set up along the soil moisture sensors in the same field. It provides data to estimate the evapotranspiration (ET). Dr. Xinhua Jia is showing ABEN freshman Connor Yaggie how to download the data from the Campbell Scientific CR3000 datalogger after installation of the system.

Measuring Soil Moisture in the Field

The Stevens Hydra Probe II soil moisture and salinity sensors are used to measure soil moisture, electrical conductivity and temperature at 7 depths below the surface, i.e., 5 cm, 15 cm, 30 cm, 45 cm, 60 cm, 75 cm and 90 cm. The soil moisture and other parameters are measured at two sites, on the tile and in-between tiles.

ABEN freshman Connor Yaggie is pushing the sensors into the soil and PhD. student Debjit Roy is taking soil samples along the sensors.

Campbell Scientific CR1000 datalogger is used to collect data. A 12V battery with a 10W solar panel provide power consumed by the datalogger and sensors.
