* Slowing Chinese demand also weighs on prices

CHICAGO, March 1 (Reuters) - Chicago Board of Trade (CBOT) soybean futures turned higher on Friday, after hitting three-year lows the previous day, although sluggish exports and hefty global supplies continue to weigh on prices, traders said.

Any rallies were limited by tension between uncertainty over mainland China's import demand and forecasts of a huge Brazilian soybean crop despite a tough growing season, they added.

Agribusiness consultancy StoneX on Friday raised its forecast for Brazil's 2023/2024 soybean crop to 151.5 million metric tons, citing improved climate conditions in a season marked by excessive heat and dryness in key production regions.

News of global crop trader and processor Bunge accepting 348 contracts delivered against CBOT March soybean futures added some early support to the soy complex, analysts said, signalling commercial demand for the commodity.

The most-active soybean CBOT contract added 0.5% to $11.46-1/2 a bushel, as of 1713 GMT. The market hit its lowest level since November 2020 at $11.28-1/2 a bushel on Thursday.

Meanwhile, the wheat futures market faced headwinds from ample Black Sea supplies and mounting questions about when shipments booked by China will be shipped.

"There's a massive China export book, and we're just not seeing the shipments happen," said Angie Setzer, partner of Consus Ag Consulting. "There's a growing sense in the market that some of these Chinese bookings might get rolled forward."

CBOT wheat was down 3.34% to $5.57 a bushel, while Corn fell 1.4% to $4.23-1/2 a bushel, pressured by wheat.

The Biden administration will delay the planned Friday announcement of its revised climate emissions model for ethanol due to disagreements, two sources familiar with the matter said.

This extends uncertainty on whether the corn-based fuel will qualify for new sustainable aviation fuel (SAF) tax credits.
