Recently both PITs have had technical sessions on the value of moisture probes. Rob O’Connor and Dale Board, both from DEDJTR, have been talking to PIT farmers about the benefits and challenges of using soil moisture monitoring tools. A summary of Dale’s previous research into these tools in the region can be found here: http://irec.org.au/farmer_f/pdf_186/Soil-moisture-monitoring.pdf
Soil moisture monitoring provides a tool that enables irrigators to make more informed decisions regarding water requirements of various crops, which can result in on-farm water efficiency gains and increased productivity.
Some key lessons discussed for moisture probe sessions:
Moisture probes allows you to refine your irrigation schedule to increase water efficiency and productivity
You get the best value from moisture probes when you aim maximise production rather than to minimise absolute water use
Moisture probes allow you to maximise return on investment in farm layout and deli...
The Stewart PIT spoke at length about the data that could be collected on the farm to inform some key management strategies for the group. In the first couple of meetings the watering strategy utilised on the farm, in particular the longer irrigation intervals that Kelvin and Don use, were of particular interest to the other farms in the group. Some felt that the longer intervals might be causing a yield penalty where others were keen to know if they could implement a longer irrigation interval to save on water use without compromising on pasture accumulation. The PIT team discussed the monitoring and measurement methodology and it was agreed that Accelerating Change would measure the impact of different watering strategies on the Stewart’s lucerne and perennial pastures.
The following methodology was agreed to. Each square represents a different irrigation bay.
On the Stewart farm, we are taking regular weekly readings to examine pasture growth at different irrigation intervals and on...
