7/29/2021 By Julie Ingwersen CHICAGO, July 29 (Reuters) - Chicago Board of Trade (CBOT) wheat futures rose on Thursday, with the front contract rising above $7 a bushel for the first time in a week after findings from an annual U.S. crop tour showed the impact of drought in the northern Plains spring wheat belt. Corn and soybean futures closed higher on fears that the drought also may curb corn and soy prospects. CBOT September wheat settled up 16-1/2 cents at $7.05-1/4 per bushel after reaching $7.06-3/4, the contract's highest since July 22. Minneapolis Grain Exchange September spring wheat ended up 14-3/4 cents at $9.18-1/2.
