  1. Where is the Profit? Corn on Corn vs Corn -Soybeans SEIARA Annual Meeting March 4, 2004

  2. Corn on Corn vs. Corn on Soybeans; General Considerations • Rotation effects on yields • Rotation effects on costs of production, especially insecticides and N • Market considerations • Effects on pest cycles • Effects of the government programs

  3. Continuous Corn and Corn-Soybean Tillage Study • Started in 1990 • Two soil types • Kalona • Nira • Three tillage systems • No-Till • Ridge/Alternative • Chisel Plow-Disk

  4. 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

  5. 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
