Sensor-controlled irrigation systems in Nursery plots at Watkinsville, GA (near Athens) and at the UGA Research and Education Center campus at Tifton, GA
Two identical soil moisture sensor-controlled irrigation systems have been installed on the horticulture farm in Watkinsville, GA (near Athens) and on the UGA campus in Tifton.
Both of these research sites allow for irrigation control of 16 plots, using 10HS soil moisture sensors. Like the greenhouse systems, these irrigation systems are controlled using a CR10 datalogger and relay driver.
We used these sites during summer, 2010 to look at the effects of substrate water content on growth and water use of Hibiscus acetosella. Both of these irrigation systems performed very well, with good control over substrate water content.
