|The wireless weather station in a subsurface irrigation (SI) field. It measures photosynthetic active radiation (PAR), air relative humidity (RH) and temperature, rainfall and soil moisture and temperature at 5 cm, 15 cm and 30 cm below surface.|
|The oxygen level in the water has been monitored by a CS511-L dissolved oxygen sensor with a CR1000 datalogger, both from Campbell Scientific, Inc.|
|The plant comparison of control and waterlogging treatment is shown above. The control is in the leftmost. To the right, the plants are waterlogging treated of one, three, five and seven days respectively.|
|A Geonics EM38-MK2 Ground Conductivity Meter was tested in the field.|
|The ground conductivity mapping was implemented using a customized EM38-MK2 system as shown above. The signals were transmitted to and recorded in a Trimble Juno 3 Series Handheld GPS for further analysis.|
