Corn Planting and Soybean Seeding Rate
More than half of Illinois corn was likely planted by April 19. Should remaining fields be reworked if rainfall prevented planting a tilled field? An accurate answer is hard to give. Soybean planting should be finished up by mid-May in most areas if weather patterns hold. Growing conditions in 2003 resulted in variable, but often small, seed size; setting exact seed drop rates remains challenging. Guidelines for choosing seeding rates are presented. more
