The July WASDE report showed much lower than expected corn ending stocks for old and new crop, lifting December corn 4 cents after an early decline. Soybeans closed lower on slight ending-stock revisions and weak export demand, while wheat fell sharply after a surprise increase in US wheat production and ending stocks.
The USDA report's tighter corn stocks support feed grain prices, while bigger wheat supplies weigh on wheat values that compete with corn in rations.
