Modern irrigation systems mean the Turnbull family have better control, but it's a big change from what it was like on the farm 125 years ago.

It was a tip from a friend that led Edward Turnbull to a tiny corner of Northern Victoria in 1892.

After leaving his home in England, the 41 year-old travelled first to Adelaide, SA, but he soon received a letter from a friend claiming prospects were better across the border.

In a place called Ardmona, the land and water were said to be cheap, the transport good and infrastructure for gravity flow irrigation was in place.

Without hesitation, Mr Turnbull purchased 28 acres on Ardmona Road.

This parcel of land, an orchard of vines and fruit, was passed from one generation to the next and now this tale spans five generations.

A stone’s throw from the original homestead, a direct line of Turnbull fruit growers has lived and worked ever since.

Ross Turnbull, 77, remembers what irrigation looked like in the 1950s and said back then it hadn’t changed since his great grandfather bought the property.

“We used to cultivate the land so that it was soft and we used to form channels and banks in the orchard,” Ross Turnbull said.

“We didn’t use pumps; we would survey the slopes by eye and the water would run down to the end.

“Later we stopped cultivating and we started using sprinklers staggered throughout the orchard.

“Then I figured out that if we used hoses we could move them around and we needed fewer sprinklers, in fact we only needed a third of the infrastructure.

“Low volume emitters came next, mini jets and dripper systems.”

The Turnbull orchard is on the Central Goulburn backbone and was modernised during stage one of the Connections Project.

During this year’s Winter Works, the Kelvin Property at Tatura East, which is on the Central Goulburn Number Four Channel, was remediated and upgraded.

At this site 2 kilometres of channel was remediated and GCL lined, generating water savings of about 505ML.

The fifth generation now manage the property with Chris Turnbull, 42, and Alex Turnbull, 39, relying on their mobile phones to work irrigation systems and to access data.

“There is no doubt my ancestors used a lot more water than we do,” Ross Turnbull said.

“The old system would break and the undulating orchard was hard to water evenly. Some trees received too much water while others didn’t get enough.”

For Mr Turnbull, a modern system means having better control over irrigation, which evens out the health of the trees.

“We are heading into an era where we are becoming increasingly efficient in every way when it comes to agriculture. We simply have to.

“The fact is water is a shared resource and it needs to be managed well.

“If Dad knew that the irrigation upgrades mean some farmers can switch the water on lying in bed holding a mobile phone, he would be quick to tell you it was much harder back in his day. But I reckon he would be impressed.”
