Nutrien Ltd is in talks for a potential deal involving Australian rural services firm Ruralco, the Canadian fertiliser maker says, following a media report about a possible takeover of Ruralco.

No agreement has been reached yet and there is no assurance that there will be one, Nutrien added on Tuesday.

Ruralco, which had a market value of $321.5 million ($US230 million) as of Tuesday, was unavailable for comment outside usual business hours.
