On July 13, 2016, Duke PhD candidate Zach Brecheisen, with assistance from his advisor Dan Richter and Jay Austin, installed TDR probes at 25-cm depth in three land-use treatments: cultivated field, pine forest, and hardwood forest. Earlier TDR probes were installed at 50 cm depth in the same locations. The TDR probes are used to monitor soil moisture. Zach is also continuously monitoring soil CO2 and O2 at two depths in the same plots.
