SINGAPORE, Oct 5 (Reuters) - Chicago corn lost more ground on Thursday, while soybeans eased as both prices of both crops came under pressure from advancing U.S. harvest and ample global supplies.

Wheat futures edged higher, recouping last session's losses.

FUNDAMENTALS

* The most-active corn contract on the Chicago Board of Trade (CBOT) gave up 0.2% to $4.85 a bushel, as of 0010 GMT and soybeans gave up 0.2% to $12.70 a bushel.

* Wheat climbed 0.1% to $5.60-1/2 a bushel.

* Freshly harvested U.S. corn and soybeans supplies are entering the market and weighing on prices.

* The U.S. Department of Agriculture said U.S. harvests of corn and soybeans were both 23% complete, slightly ahead of their respective five-year averages.

* Commodity brokerage StoneX on Monday raised its estimate of U.S. 2023 corn production to 15.202 billion bushels from 15.102 billion in its previous monthly report released on Sept. 6.

* The firm forecast U.S. soybean production at 4.175 billion bushels, up from 4.144 billion previously.

MARKET NEWS
