Background

GDots are a new irrigation management tool to the Burdekin. A GDot is a gypsum block that is buried in the root zone of the crop with a cord that leads to a head unit. The head unit has 7 yellow dots that drop off as the soil dries out. That is, at <10kPa, the GDot has 7 dots. The dots flick to black as the soil dries, so when the soil tension is >100kPa, there are no dots on the GDot.
