CANBERRA, Feb 1 (Reuters) - Chicago wheat futures trod water on Thursday amid weak demand and falling Russian export prices, while soybeans and corn hovered above multi-year lows on the prospect of ample supply.

FUNDAMENTALS

* The most-active what contract on the Chicago Board of Trade (CBOT) was up 0.1% at $5.95-3/4 a bushel by 0123 GMT after falling 5.2% in January.

* CBOT soybeans fell 0.4% to $12.17-1/2 a bushel and were close to Tuesday's two-year low of $11.88, while corn slipped 0.3% to $4.46-3/4 a bushel, and was trading near a three-year low of $4.37 hit twice during January.

* Falling wheat prices in Russia, which still has a large surplus to shift before this summer's harvest, have kept the wheat market's focus on Black Sea supplies.

* Russia's agriculture minister, meanwhile, said the country would increase the area for the 2024 harvest by 300,000 hectares to 84.5 million hectares, bolstering expectations for another bumper crop.

* Euronext wheat futures hit contract lows. CBOT wheat traded at a three-year low of $5.40 in September.

* Data showing a fourth consecutive monthly decline in China's manufacturing activity did nothing to ease concerns about Chinese demand for agricultural imports.

* The U.S. dollar also strengthened during January, making U.S. farm products less attractive to importers.

* Commodity funds - which hold net short positions in CBOT wheat, corn and soybeans - were net sellers of wheat and corn futures on Wednesday while buying soybeans, traders said.

* Argentina's farm regions are bracing for a heat wave over the next week, followed by rains that will douse the northern, western and southern regions but largely miss the center-east zone, the Buenos Aires grains exchange said.

* India's major wheat-growing areas in the north could experience above normal temperatures in February, the country's weather office said, raising concerns about crop yields.

* Ukraine's agricultural maritime exports are expected to fall to around 3.8 million metric tons in January from around 6.1 million tons in the prior month, brokers said.

* The European Commission proposed measures to limit agricultural imports from Ukraine and offer greater flexibility on rules for fallow land in a bid to quell protests by angry farmers in France and other EU members.
