NEW YORK, Oct 10 (Reuters) - Chicago soybean futures rose on Tuesday, rebounding sharply from early losses on lift from technical trading and data showing a pickup in exports of the American oilseeds.

Corn prices weakened, and wheat futures fell sharply.

The most-actively traded Chicago Board of Trade soybean contract rose 0.6% to $12.71-1/2 per bushel. In early trading it had fallen to $12.54-1/4, its lowest since December 2021.

"People trading the market right now don't have a lot of staying power, they're not building for the long-term," said Scott Harms, senior ag risk adviser with Archer Financial Services.

He said the choppy trade was caught between technical short-sellers without the leverage to "hold it down," and not enough bullish news "to put together a large rally."

Soybean farmers did get a ray of light when the U.S. Department of Agriculture (USDA) reported export inspections of

1.036 million tons

of soybeans for the week ending Oct. 5, the highest since mid-February. The release was marred after USDA was forced to

correct

even-rosier figures released earlier in the day.

Weekly USDA data

showed

the soybean harvest 43% complete, slightly ahead of an average of

analysts polled by Reuters

, with the crop condition declining somewhat to 51% rated "good" or "excellent" compared with 52% in the prior week.

CBOT wheat fell after a short-lived rally in the prior session fuelled by a spike in energy prices. December soft red winter wheat shed 2.5% to settle at $5.57 a bushel.

Traders were adjusting positions ahead of the USDA's Oct. 12 World Agricultural Supply and Demand Estimates report.

Corn prices fell 0.6% to $4.85-1/2 a bushel, as traders awaited weekly USDA crop progress data. The report, released after the close, said the corn crop was 34% harvested as of Sunday, in line with estimates.
