As a change from more still photos, here's a (very) short video of the irrigation working during a site visit:
The sprinkler heads are set to have a 90 degree operational arc, so theoretically the water falls within the experimental plot. The water for this comes from the storage butts that act as reservoirs for the intercepted 50% rainfall from the droughted plots. I need to tweak the float switches still, to ensure they're all switching on and off at the same water depth, but otherwise, the system seems to be working so far.
This is something I'll be checking on regularly over the winter, as part of the ongoing monitoring of the site, the system, and the field generally.
