In the 2011/12 season Greenvale Pastures put six soil moisture probes (neutron probes) across six different soils within the one paddock (red dots on map).

The paddock was in wheat in the 2011/12 season and weekly soil moisture probe readings were being taken with the average of all six used for irrigation scheduling in the paddock.

After completing the season and yield mapping it was realised that the wheat yield was suppressed considerably in what should have been the better yielding parts of the field.
