* Arrested at airport a month after pulling out of cartel
* Potash prices likely to fall now cartel dissolved
* Potash a key source of currency for Belarus

MOSCOW, Sept 8 (Reuters) - Vladislav Baumgertner has the fluent English, Western business degrees and meteoric career that typify Russia's young executive elite, but the boss of Uralkali, the world's largest potash producer, is now more in need of Soviet-era survival skills.
For two weeks Baumgertner, 41, has been held in a dank Stalin-era Belarusian cell, facing up to 10 years in jail on charges of abusing power and seeking gain at the expense of Belarus while chairman of a joint venture cartel, Belarusian Potash Company (BPC), which until last month controlled Russian and Belarusian exports of the fertiliser ingredient.
Belarus, which has long bridled at what it believes is Uralkali's aim to take over its own producer Belaruskali, was angered by Uralkali's abrupt exit from BPC last month, a move likely to lower prices, hit a key source of hard currency and hurt Belarus's rickety economy.
The Belarusian Investigative Committee has not provided details on the charge, though among comments it made at the time of Baumgertner's arrest are allegations that he and others at BPC provided discounts on product to some buyers without telling the Belarusians, redirected ships to take Uralkali product instead of Belaruskali's, and cancelled some BPC contracts, promising partners a Uralkali alternative at lower prices.
Uralkali denies any wrongdoing and has said previously that Baumgertner did not have the powers the Belarus authorities say he abused.
HANDCUFFED AT THE AIRPORT
After travelling to Belarus for talks less than a month after pulling out of BPC, Baumgertner was handcuffed at the airport as he was leaving on Aug. 26 and thrust into the heart of an acrimonious battle between Moscow and Minsk.
He, along with Uralkali's chairman, former Kremlin chief-of-staff Alexander Voloshin, and the company's leading shareholder, Suleiman Kerimov, had been invited to Belarus by the country's prime minister. Only Baumgertner went.
He is being held in the pre-trial detention centre of the Belarusian KGB, known to locals as 'Amerikanka', or the American one, apparently after a Chicago jail.
His requests have been for unspecified medication, and for Tolstoy's "Anna Karenina", an 864-page classic that will fill several long days.
Conditions are likely to be tough for the slight Baumgertner.
Anatoly Lebedko, Belarusian politician and leader of the United Civic Party, spent 108 days in Amerikanka for taking part in protests after President Alexander Lukashenko was re-elected in 2010.
He described the cells, the largest 2.5 metres by 5 metres, as dark, grey, crowded and damp. Lebedko was one of six in a cell built for four, in temperatures typically below 14 degrees Celsius (57 Fahrenheit).
"There are many ways to add pressure. If you're not ready, if you are not physically ready for conditions which are far from comfortable, it will be very hard for you," he said.
Prisoners are taken from the cells twice a day to the toilet facilities, though Lebedko says there are "VIP cells" with internal toilets.
Baumgertner is not the first top Russian executive to end up in jail. But it would have been a considerable shock for him, as it was for those around him, both competitors and friends said.
"The board was apprised of the history, of the difficulties of the apparent divergence of objectives (between the cartel partners) that had been progressively building," said Uralkali Deputy Chairman Robert Margetts.
"Of course we spent a lot of time on the commercial and financial risks and the consequences (of pulling out) - but I have to say, I had not considered this."
Baumgertner is by all accounts a soft-spoken boss, with a cheerful countenance. Rivals and colleagues describe a methodical, tough negotiator whose approach to staff and the public is a far cry from Soviet-trained predecessors'.
"He is a man of his word, a rare thing in our times," said Maxim Volkov, former chief executive of Russian fertiliser company Phosagro.
Baumgertner, who had been in the utilities sector and later studied in London, joined Uralkali for the first time in 2003 as chief commercial officer, rising to chief executive in 2005.
He left in 2010 when demoted under the then owners and became CEO of another fertilizer producer, Silvinit. Supported by key shareholder Kerimov, he returned in 2011 after Uralkali bought Silvinit.
He is described as having built a young, ambitious management team, and praised for his efficiency, perhaps a product of his engineer's training. In a country where bad news is often muffled, his instinct for openness stands out, including during a damaging 2006 flood at a mine in the Urals and when dramatic sinkholes appeared in the potash mining town of Berezniki.
"Vladislav, as (CEO) at the time and despite some people at Uralkali being reluctant to go public, opened all the doors, invited the best consultants around the world to help and did not try to hide these issues from the public," said Henry Rauche, chief executive of Ercosplan, a German engineering and consulting company working for the potash industry.
"He was a refreshing change after the Soviet style leadership in the former Russian potash industry."
He has not been seen in public or photographed since his arrest.
