Farmers in race against weather

Hail and torrential rain have battered and bruised crops across the State in the past few weeks, as farmers race to get crops in the bin.

At Yarranabee farm, 25km south-east of Narrogin, the rain gauge recorded 75mm from last Thursday's thunderstorm.

The barley crop and pastures faired the worst - about two kilometres of fencing was also washed out.

Operations manager Ashley Forrest said more than 600 hectares had been hit.

"Both our barley and feed which we sprayed has now been wrecked, however, our barley crop is of most concern to us," Mr Forrest said.

"The quality of the crop will be diminished and we won't know the full effect until after harvest but we could be looking at a difference of $100 per tonne."

With the Bureau of Meteorology forecasting rain for the Upper Great Southern region over the next week, Mr Forrest hopes the rain is kept to a minimum.

"If we get a similar rain like this in two weeks' time, it will do a hell of a lot of damage," he said. "It will have the potential for huge damage for all of our crops, which would affect us much more than Thursday's thunderstorm."
