Several Iowa long-term experiments are studying rotation and N fertilization effects on corn yield (seeNitrogen fertilization for corn following corn). A unique piece of information provided by an experiment conducted since 1979 at the Iowa State University Northeast Research and Demonstration Farm near Nashua is the evaluation of yield and response to N of corn grown continuously and one, two, or three times after soybean among other rotations. The N rates for corn have been 0, 80, 160, and 240 lb N/acre/year as granulated urea applied and incorporated in the spring
