Yields of corn following corn and soybean following soybean are usually less than when each crop follows the other, and reasons cited for this include N immobilization and allelopathy, and the lack of a poorly understood "rotation effect". The objective of this study was to attempt to overcome this lack of rotation effect by manipulating N rate, N form and crop residue, thus testing the hypothesis that part of this rotation effect may be due to N availability as influenced by its proximity to crop residue (and root growth pattern) in the soil. Experiments were conducted in 1989 and 1990 on Drummer silty clay loam (Typic Haplaquoll) and Flanagen silt loam (Aquac Argiudoll) at Urbana, IL. Dry weight of V7 and R8 corn plants, total N concentration of V7 and ear leaves, NO3- in stalks of V7 plants and in cut-stem exudate of R1 corn plants and grain yields were all lower in corn grown in the presence of corn residue than without residue or in soybean residue, while harvest index was increased by corn residue. The beneficial rotation effect when corn follows soybean was eliminated by the addition of corn residue, and was not dependent on the presence of soybean residue. Recovery of N fertilizer was greatly influenced by residue and N rate, indicating that plants were more efficient in taking up N when grown in soybean and corn residue and that recovery decreased as rate of N increased. Form of fertilizer N did not influence yield, dry weight and total N concentration of corn following corn and corn following soybean ...
