SINGAPORE, June 23 (Reuters) - Chicago corn futures edged lower in early Asian hours on Friday, as traders booked profits after a recent rally over concerns amid dry conditions in the key growing areas of the U.S. Midwest, although they were still poised to post weekly gains.

Wheat and soybeans also both edged lower but wheat still headed for a weekly gain, while soybeans were set to post weekly drop.

FUNDAMENTALS

* Corn futures were down 0.9% at $6.15-1/4 a bushel, as of 0126 GMT, after hitting a more than two-month high on Wednesday.

* The most-active soybean contract on the Chicago Board of Trade (CBOT) was down 0.4% at $13.34 a bushel, and wheat futures gave up 0.5% at $7.48-3/4 a bushel after hitting their highest since late-February on Wednesday.

* For the week, soybeans are down 0.7%, corn gained about 3.0% while wheat gained 8.8%.

* Russia is 99.9% certain to quit a U.N.-brokered deal on the safe wartime passage of Black Sea grain next month because it no longer needs Ukrainian ports to export ammonia, a senior Ukrainian diplomat said.

* The worst U.S. Midwest drought since 2012 expanded over the past week despite mild temperatures as a lack of rain across the heart of the American farm belt threatened newly seeded corn and soybean crops, climatologists said in a weekly report.

* Argentina's 2022/23 corn production is expected to be 34 million metric tons, down from the 36 million forecast previously, the Buenos Aires grains exchange said on Thursday, as the South American country grapples with the fallout of a major drought.

* Commodity funds were net sellers of Chicago Board of Trade corn, soybean and soymeal futures contracts on Thursday, traders said. The funds were net buyers of CBOT wheat and soyoil futures.

MARKET NEWS
