SINGAPORE, Aug 14 (Reuters) - Chicago soybeans were largely unchanged on Wednesday, trading close to their lowest level in four years as expectations of a record U.S. harvest and lacklustre demand from top importer China pressured prices.

Wheat slid amid plentiful Black Sea supplies, while corn fell for a second session.

FUNDAMENTALS

* The most-active soybean contract on the Chicago Board of Trade (CBOT) was flat at $9.62-1/2 a bushel, as of 0010 GMT, matching Tuesday's low which was the weakest since September 2020.

* Wheat gave up 0.3% to $5.27-1/4 a bushel and corn fell 0.1% to $3.97 a bushel.

* The U.S. Department of Agriculture (USDA) raised its estimates for corn and soybean production in its monthly supply-demand report. It put its soybean crop projection at a record level.

* Higher U.S. output comes as China is reducing purchases amid a glut of supplies from Latin America.

* China's most-active soymeal and rapeseed meal futures tumbled to their lowest in more than a year on Tuesday as high soymeal inventory and a forecast of record U.S. soybean production added to expectations of abundant supplies.

* In the wheat market, bearishness stemmed from large Black Sea supplies.

* Egypt's state grains buyer said it bought 280,000 metric tons of wheat in a tender on Monday, falling well short of its target of 3.8 million tons.

* Separately, the country's state commodities buyer GASC is in talks to buy 30 cargoes or up to 1.8 million metric tons of wheat from sellers including Russia, traders in Europe and the Middle East said.

* The USDA's August forecast for Ukraine's corn production exceeds domestic estimates as it does not fully take into account the impact of a damaging heatwave, Ukrainian officials, analysts and traders said.

* The USDA report shows Ukraine is expected to harvest 27.2 million metric tons of corn, while domestic analysts and brokers anticipate 24 to 25 million tons.

* Commodity funds were net sellers of CBOT soybean, soymeal, soyoil, corn and wheat futures contracts on Tuesday, according to traders.

MARKET NEWS

* Stocks jumped and bond yields fell on Tuesday after data showed U.S. producer prices increased less than expected in July, reinforcing market expectations that cooling inflation will allow the Federal Reserve to cut interest rates soon.
