A large-scale field experiment was established in 1985 at 3 eastern CO locations to examine alternatives to the traditional wheat-fallow cropping system. All new treatments used no-till instead of tillage intensive management. Rotations include wheat-fallow, wheat-corn-fallow, wheat-corn-millet-fallow, and perennial grass. After five years, the more intensive cropping was giving greater grain output, nitrogen use efficiency, and water use efficiency than the wheat-fallow system. Organic matter levels also appear to be increasing. The research is also examining each strip plot at three landscape positions: toeslope, sideslope, and summit.
