Since 2013 Mr Causley, a fifth generation Clarence Valley farmer, now living on tiny Warregah Island, has avoided over working his sandy loam in favour of minimal till.
Pulling an Illinois-built Nifty-Ag strip tiller behind a 90hp John Deere tractor he can prepare 4ha an hour while burning 12 litres of diesel compared to the much slower rotary hoe which required 30l/hr worth of fuel.
“The worst thing about the rotary hoe was that it destroyed soil structure and if we then got two inches of rain the ground went rock hard and I’d have to start all over again,” he said.
“Rain used to be my enemy. Now it’s my friend.”
