Fertilizer giants Potash Corporation of Saskatchewan and Calgary based Agrium are in talks regarding an equal merger.

The deal, which is very preliminary could be worth a reported $37 billion.

Premier Brad Wall was contacted by both company's presidents Tuesday morning.

"The interests of Saskatchewan have been at the forefront of even these preliminary discussions," he stated to reporters. "Those interests of course are jobs, the taxes paid, the economic impact of these companies to Saskatchewan, that these considerations have been paramount in preliminary discussions and should these discussions advance that they would continue to be a top priority."

The merger talks come as the fertilizer industry struggles with a steep drop in prices in recent years that has forced PotashCorp to slow their production including shuttering a mine in New Brunswick.

Wall says is this potential merger does come to fruition it could mean more jobs in Saskatchewan.

"I've shared this with both CEO's, our government would want to even begin proactively working on some ideas that would make Saskatchewan an attractive place for even more jobs in the future from a new merger entity."

No agreement has been reached and there is no assurance that any transaction will result from these talks.

Also, unlike the "foreign takeover" attempt by BHP Billiton, this potential move could be much more clear cut.

"My understanding is the Investment Canada Review Process that was triggered by that proposed takeover would not be triggered in this regard," Wall explained. "We would absolutely have an interest at stake and as a government we would want to protect Saskatchewan's interest and maybe see them furthered."

PotashCorp operates five mines in Saskatchewan: Lanigan, Allan, Cory, Patience Lake and Rocanville. Agrium's sole operation in the province is its Vanscoy mine.
