Warmer days and a lack of rain has put some winter cropping operations in a dire state with landholders getting ready to bale paddocks which have no hope of a grain harvest.

NSW Farmers, Wagga and District Branch chairman Alan Brown said the drought conditions were quickly heading south.

He said the make or break time for this region would occur in the next two weeks. Falls of up to 10mm were forecast this weekend, and while it would offer a reprieve, it may not be enough for some.

Livestock producers certainly haven't escaped the dry times and the yarding at Wagga's cattle sale on Monday was 4800. Restocker activity on the store cattle was subdued inline with the dry season.

Mr Brown said there were signs of stress in crops, due to lack of moisture and it was certainly fair to say farmers were "tuning up the balers." "The big dry is on the march south and anything north of Ariah Park is shot," he said.

"We have gone from frosts to heat in the space of a couple of days," he said.

Despite the fact large portions of crop may be cut for hay this commodity was still considered valuable as livestock feed given the shortages of fodder throughout the country.

Meanwhile, canola growers can attend information sessions on September 11 to learn about the profitability of the crop.

NSW Department of Primary Industries (DPI) research and development agronomist, Rohan Brill, said the Optimised Canola Profitability Roadshow draws on five years of ground-breaking research to best manage crops.

He said there will be a focus on answering questions which will really make a dollar difference
