Researchers investigated the impact of increasing crop rotation length and complexity on crop yields in organic agricultural systems over a ten year period. They found that longer, more complex rotations using corn, soybean, wheat, and hay offered up to 30% greater corn yield than a simple corn-soybean rotation. The additional crop variety and rotation time helps provide adequate nitrogen and decrease weed competition, thereby increasing production.
