This VUSASESGISS is a very sensitive device that needs gentle treatment. I did not know this either as we had only used it on the beach where it always gave ample water no matter what you did. Hey, that is strange - there's no water, said Corné when Joris pulled the syringe and no water emerged for the tenth time that day. At some stage Joris got the idea to suck on the tube rather than to use the syringe, and suddenly water did emerge. Now we were in business. Seemed that we had pulled the syringe to eagerly all the time. This opened up a whole new venue for sampling and Anne was the first to profit taking a 10 cm resolution soil water profile for analysis.

In the meantime, the sapflow system had been operating and Louise and Patricia decided that it was time to collect some data and change the heater battery. Wisely they brought an umbrella as computer screens and sunshine do not work together well.
