Soy up 6-8 cents, corn up 3-4 cents, wheat mixed

CHICAGO: Following are US trade expectations for the opening of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Tuesday.

WHEAT - Mixed

* Activity in corn futures will likely help give direction to the wheat market, traders said.

* Concerns about poor prospects for US wheat supplies on the export market are weighing on wheat futures, although short-covering could underpin prices, traders said.

* CBOT December soft red winter wheat last traded up 2-1/2 cents at $4.75 a bushel. The contract hit a one-week low overnight.

* K.C. December hard red winter wheat was last up 1 cent at $4.07-3/4 a bushel and MGEX December spring wheat was last up 1/2 cent at $5.17-1/2.

CORN - Up 3 cents to 4 cents per bushel

* Corn futures are getting a boost from a decline in US crop condition ratings and lower production projections from the Pro Farmer Midwest Crop Tour, traders said.

* Scouts on the crop tour estimated corn yields in Ohio and South Dakota will be down from a year ago after heavy rains disrupted plantings this spring.

* Traders will wait for more field reports from the four-day crop tour.

* The USDA, in a weekly report issued late on Monday, rated 56% of the US corn crop in good-to-excellent condition, down from 57% a week earlier. Analysts had expected the rating to remain unchanged.

* CBOT December corn last traded up 5 cents at $3.79-1/2 a bushel.

SOYBEANS - Up 6 cents to 8 cents per bushel

* Declining crop conditions and Pro Farmer's tour estimates were seen to be supporting soybean futures.

* The Pro Farmer crop tour does not project soybean yields but scouts estimated a lower number of soybean pods in a 3-by-3-foot square in Ohio and South Dakota, compared to last year.

* The USDA on Monday cut its soybean crop rating to 53% good-to-excellent from 54% a week earlier. Analysts had expected the rating to hold steady.

* Expectations for beneficial rains in the US Midwest could weigh on prices, analysts said.

* CBOT November soybeans last traded 6-1/4 cents higher at $8.72-3/4 a bushel.
