SINGAPORE, Nov 29 (Reuters) - Chicago wheat edged higher on Tuesday after hitting a more than three-month low in the previous session, although ample supplies from the Black Sea region following an extension of the export corridor deal curbed gains.

Soybeans edged lower after closing higher in the last session, while corn eased.

FUNDAMENTALS

* The most-active wheat contract on the Chicago Board of Trade (CBOT) rose 0.2% to $7.82 a bushel, as of 0125 GMT, after dropping on Monday to its lowest since Aug. 22 at $7.73-1/4.

* Soybeans fell 0.2% to $14.54-3/4 a bushel and corn was down 0.2% at $6.70 a bushel.

* Cheap supplies from Russia and elsewhere in the Black Sea are leading to competition for U.S. suppliers.

* Russian wheat prices rebounded slightly last week from a week earlier, when they fell on the extension of the Black Sea grain supply deal, analysts said on Monday.

* Prices for Russian wheat with 12.5% protein content and for supply from Black Sea ports in December were at $317 a tonne free on board (FOB) on Friday evening, up $3 from a week earlier, the IKAR agriculture consultancy said in a note.

* Soybean prices slid even though dryness in Brazil lent some support to the market.

* Brazilian soybean planting reached 87% of the estimated area in the 2022/2023 cycle amid dryness in some center-western farms that has growers concerned, according to agribusiness consultancy AgRural on Monday.

* Although sowing is slightly behind last season's pace, Brazil is poised to harvest a bumper crop based on historical yield trends and the estimated size of the planted area, AgRural said.

* Large speculators cut their net long position in CBOT corn futures in the week to Nov. 22, regulatory data released on Monday showed.

* The Commodity Futures Trading Commission's weekly commitments of traders report also showed that noncommercial traders, a category that includes hedge funds, increased their net short position in CBOT wheat and cut their net long position in soybeans.

MARKET NEWS

* Wall Street equities deepened losses on Monday while U.S. oil futures reversed course to settle higher on production rumors after starting the day mired in worries that China's strict COVID-19 restrictions would stunt global economic growth.
