Corn on Corn vs. Corn on Soybeans; Long Term Field Studies
Rotation fertility studies from 1979 Rotations: CC, CSb, CCSb, CCCSb, Sb 4 N levels: 0, 80, 160, 240 Data from Ken Peckinovsky and Antonio Mallarino

Conclusions Corn yields increase for corn following any other crop
Corn/Soybean is the most profitable rotation with CCSb second under normal conditions Significant pest pressure with more severe impact on soybean yields will influence the results Market prices influence most profitable rotation but C/Sb still is most profitable
