NORTH West Victorian graingrower, Aaron Sanderson, will sell about 80 per cent of his crops through Agfarm's broking service and pools this season and can't speak highly enough of the company's new role in grain business.

"They're independent, they check the credentials of every potential buyer on the scene and with one phone call from me they organise the lot," said Mr Sanderson who grows 1800 hectares of lupins, faba beans, field peas, wheat, barley, canola and oats at St Arnuad in the Wimmera.

The Agfarm convert estimated his price premiums secured from buyers by using the broking service and the time he saved not chasing around for sales (and sale payments) had repaid his commission costs "three or four fold".

Mr Sanderson first tested the water with Agfarm four years ago, taking advantage of the Victorian Farmers Federation's offer to connect growers with the non-aligned broking service.

By 2010-11 the company's Bendigo trading office was selling 50pc of his grain and he used its research to check out summer crop options after his property "Bromley Park" was drenched by unseasonally wet conditions early last year.

Although still handling a fifth of his grain sales himself, this season Mr Sanderson also put a big portion of his wheat into Agfarm's Advantage pool, opting for five monthly payments that will reflect market trends from February to June.

"With so much change in the market and so many overseas names coming in I don't think grower loyalty to individual grain buyers - even the traditional names - is so strong nowadays. Grain companies probably aren't so loyal to growers, either.

"I really appreciate having an independent broker bending over backwards to do all the hard work and stay abreast of the market - if you're working alone you've often got so little time to lock in on daily prices before everybody's quotes drop away by 11am."
