Corn futures hit a four-month low as a huge US crop meets a lagging export pace. CBOT corn fell 6 cents to $4.42-1/4 a bushel and touched its lowest since July 2, while soybeans set a 2-1/2-month low.

What happened: CBOT corn futures fell to a four-month low on expectations for a large US crop and concerns over export demand. Soybeans set a 2-1/2-month low and wheat also declined. Key numbers: Corn down 6 cents at $4.42-1/4 a bushel, lowest since July 2. Soybeans down 4 cents at $12.12-3/4, lowest since August 17. Wheat down 7-1/2 cents at $5.99. Why it matters: Allendale's Rich Nelson said demand is lagging last year's pace and "we still have more ground to make up." Traders were also nervous about US soybean demand beyond China amid competition from Brazil.
