We planed to set six EC-5 soil moisture sensors at each plot in B1, with two depth, 20 cm and 40 cm, and connect the sensors to the XM 1000 datalogger. But the soil was compacted and contain lots of stones., so it was very hard to dig and insert sensors. With the help of Antonio, we finally made it.

We also established band dendrometers for each sap flow trees. The band dendrometer was home-made, following the instruction from Antonio. It was not an easy one as well, because we had to solder the very tinny wires with connectors on site. This work was largely done by Guang.

Many, many thanks!!!
