* Crop tour forecasts U.S. corn, soy crops below USDA estimates

* Forecasts of more hot, dry weather threaten U.S. soybean yields

* Second vessel leaves Odesa through temporary Black Sea corridor

CHICAGO, Aug 28 (Reuters) - Chicago soybeans and corn climbed on Monday after a U.S. farm survey predicted smaller crop production than government forecasts due to hot, dry conditions across the U.S. Midwest.

Wheat dipped on weak demand for U.S. crops, coupled with competition from cheap Russian supplies.

Chicago Board of Trade most-active soybeans gained 12-1/2 cents to $14.00-1/4 a bushel by 11:00 a.m. (1600 GMT), after reaching 14.09-1/2 a bushel, its highest since July 27.

CBOT corn lifted 6-1/2 cents to $4.94-1/2 a bushel, while CBOT wheat dipped 6-1/2 cents to $6.15-1/4 a bushel.

U.S. 2023 soybean production could total 4.110 billion bushels, advisory service Pro Farmer said after Friday’s market close, below the 4.205 billion bushels forecast by the U.S. Department of Agriculture (USDA).

"I don't think people were expecting to see that friendly of a number," said Kristi Van Ahn-Kjeseth, chief operating officer at consulting firm Van Ahn and Company, Inc. "You were seeing some yields that were better than anticipated through the states,"

Pro Farmer predicted the U.S. corn crop to be 14.960 billion bushels, below the USDA's most recent estimate of 15.111 billion bushels.

Corn futures have been weighed down by muted export demand.

Corn export inspections

for the week ended August 24 reached 597,144 metric tons, 16.96% higher than the week prior, but down 14.67% from the same week in 2022.

Soybean export inspections reached 322,149 metric tons, down 36.81% from the same week last year, while wheat export inspections of 390,364 metric tons were down 38.17% year over year.

Wheat's decline could incentivize export activity, but amid strong global supplies, U.S. wheat has struggled to attract buyers.

"We're just looking at a very weak wheat export program," said Brian Basting, commodity research analyst at Advance Trading. "We are on the outside looking in, as far as exports."

Russia

is estimated to export 5.1 million metric tons of wheat in August, up from 3.5 million metric tons a year earlier, Sovecon agriculture consultancy said. (Reporting by Christopher Walljasper; Additional reporting by Michael Hogan; Editing by Andrea Ricci)
