CANBERRA, April 16 (Reuters) - Chicago wheat futures edged higher on Tuesday but remained near four-year lows as a strengthening dollar made U.S. exports less competitive, while huge volumes of cheap grain continuing to flow from Russia also weighed on sentiment.

Corn and soybean futures fell slightly.


* The most-active wheat contract on the Chicago Board of Trade (CBOT) was up 0.1% at $5.52 a bushel by 0054 GMT. Prices fell to $5.24 a bushel on March 11, their lowest since August 2020.

* CBOT soybeans fell 0.1% to $11.56-3/4 a bushel and corn slipped 0.2% to $4.30-3/4 a bushel. Both contracts are near 4-year lows reached in February, with the markets being well supplied.

* The dollar rose to its strongest since Nov. 2 against a basket of currencies, making U.S. farm goods costlier for buyers with other currencies.

* Russian wheat export prices stabilized last week after rising for the previous four weeks, analysts said.

* Consultants Sovecon estimated that Russia would export 4.2-4.6 million metric tons of wheat in April, compared with a record-high 4.4 million tons a year ago. Russia shipped around 4.9 million tons in March, the most for any March on record.

* A U.S. Department of Agriculture (USDA) weekly crop progress report rated 55% of the U.S. winter wheat crop as being in good-to-excellent condition, down 1% from last week but still the highest for this time of year since 2020.

* The relatively strong wheat ratings underscore a shift in global grain supplies to surplus after shortages in recent years.

* Speculative investors are betting on further price falls for wheat as well as corn and soybeans and were net sellers of all three CBOT contracts on Monday, traders said.

* In soybeans, prolonged rainfall in Argentina's farming heartland fuelled fears of delays to the ongoing harvest that could cause production losses, the Rosario grains exchange said.

* U.S. soy crushers processed a record quantity of soybeans in March, although the daily crush pace slowed slightly from a record high in February, according to National Oilseed Processors Association (NOPA) data.

* India said on Monday it was likely to receive above average monsoon rainfall in 2024, in a potential boost for the country which depends heavily on the summer rains for its farm output.

* The USDA confirmed private sales of 165,000 tons of U.S. corn to Mexico, including 135,000 tons of old-crop corn and 30,000 tons of new-crop corn.


* Wall Street ended sharply lower on Monday amid rising U.S. Treasury yields, as simmering tensions in the Middle East curbed investors' risk appetite.
