New irrigation fact sheet released
A NEW fact sheet, developed to help irrigators make informed decisions on utilising irrigation water over summer, has been released.
‘What is evapotranspiration (ET) and how do I use it to schedule irrigations?’ – is a response to increasing interest in irrigation scheduling techniques.
ET is calculated by using local daily weather measurements to more accurately determine crop irrigation requirements.
The measure is now commonly used by irrigators, helping them to achieve increased yields and higher water efficiency.
Agriculture Victoria senior irrigation officer Rob O’Connor has been distributing ET data to irrigators over the past four years.
“It’s hoped the fact sheet answers some of the common questions irrigators have about ET,” Mr O’Connor said.
Mr O’Connor is currently sending actual and forecast ET information to 400 irrigators and service providers from dairy, cropping, horticulture, meat and wool each week and always welcomes new subscribers.
Mr O’Connor said ET is not meant to replace existing scheduling methods that ir- rigators already have in place.
“It complements existing methods, and provides irrigators with more confidence in their decisions, particularly when a different type of crop or irrigation system is involved,” he said.
The fact sheet can be viewed on the website agriculture.vic.gov.au/irrigation http:// go.vic.gov.au/iZBpT7.
