Chicago Board of Trade corn futures fell more than 1 percent on Monday on spillover pressure from soybeans and corn, and as forecasts for improving weather eased concerns about US planting delays, traders said. CBOT July corn settled down 5-1/2 cents at $4.00-3/4 per bushel. Ahead of the USDA's weekly crop progress report later on Monday, analysts on average expected the government to show the US corn crop was 37 percent planted.
