The crop market on Tuesday gave back most of the gains it made on Monday, pressured lower by steady U.S. crop condition ratings and China’s surprise devaluation of its currency.
Corn led the market higher on Monday and was the big loser today, with December falling about 3.4 percent.
November soybeans were down 2.3 percent and spring wheat was down 2.8 percent.
A weaker loonie, down about a half cent against the American greenback, helped cushion the blow in canola, with the November contract down 0.74 percent.
Traders on average had expected a one percentage point drop in the weekly good-to-excellent ratings of U.S. corn and soybeans due to recent dry weather in the Midwest. However, when the ratings came out Monday afternoon, they were almost unchanged.

The warm weather across the Canadian Prairies is helping to advance crop maturity. Harvest has begun on winter wheat and pulses.
Daytime heating will likely produce some local thunderstorms but the weather should be dry for most of the Prairies until the weekend when temperatures are expected to drop back to more seasonal levels. The temperature shift could bring light rain. The following week looks fairly dry across the Prairies and that should help to advance harvest activity.
The big news of the day was China’s decision to reduce its currency value by nearly two percent to spark is flagging export sector.
A weaker yuan will make it more expensive for China to import commodities such as crops, oil and minerals.
China had previously been supportive of a stronger yuan to foster its use as an international currency, but that had hurt its low-end manufacturers of low-end export goods, Reuters reported. China want to build up its domestic market and reduce reliance on cheap exports but over the weekend data showed a huge slump in July exports that Beijing could not ignore.
Analysts will be watching to see if other Asian countries allow their currencies to fall to match the drop in the yuan.
