The rain in early February was a little late to make much of a difference.
"At the end of the day it is what it is - it's what we have been given."
In 2010, Solari broke the record with a crop that yielded 15.63 tonnes per hectare.
He grew the wheat variety Firelight because of its disease resistance, he said.
The wheat crop had followed a paddock of peas, which in his experience were good for yields.
"I've come to the conclusion that what's good for people's gardens is good for our wheat."

Once the peas were harvested the straw was cut up and ploughed under.
He then used a sub›soiler implement, with 50cm-long legs, to dig down deep into the soil to break it up where it was compacted.
He had heard if the soil was loose the wheat roots would go down into the soil about 150cm.
