* Other markets react calmly to Israel attack

* Firm dollar burdens US export outlook

* Big Russian wheat shipments expected to continue

HAMBURG, April 15 (Reuters) - Chicago wheat, corn and soybeans fell on Monday as global markets reacted calmly to Iran’s drone attack on Israel and as a firmer dollar made U.S. exports more expensive for importers.

Chicago Board of Trade most-active wheat was down 1.2% to $5.49-1/4 a bushel at 1053 GMT. Soybeans were down 0.3% to $11.69-3/4 a bushel, and corn down 0.4% to $4.33-3/4 a bushel.

Crude oil fell about 1% on Monday, with the market playing down the risk of broader regional conflict after Iran's weekend attack on Israel. Europe's main share and currency markets started the week modestly higher, while bond prices dipped.

The U.S. dollar held near last week's highs, potentially dampening demand for U.S. farm exports.

“Outside markets are taking a pretty calm view of the Iranian attack on Israel and it has not caused the price turbulence you might have expected,” one German trader said.

“Attention is turning to grain fundamentals which generally remain bearish. Russian wheat is still being offered significantly more cheaply than the EU and U.S., while large-scale wheat export shipments from both Russia and Ukraine are expected to continue.”

“For corn, there are also increasing expectations that U.S. planting progress will have been extensive in the past week.”

The U.S. Department of Agriculture (USDA) is scheduled to release its weekly report on U.S. crop progress later on Monday.

Russian and Ukrainian grain exports continue to escape major attacks.

Russian wheat exports are expected to remain at over 1 million metric tons a week in April, continuing the high shipments seen since January, the Sovecon agricultural consultancy said on Monday.

In corn markets, China could cancel more shipments from Europe to ease supply pressure on its domestic market. (Reporting by Michael Hogan in Hamburg and Peter Hobson in Canberra; Editing by Janane Venkatraman and Mark Potter)
