Organic corn: Increasing rotation complexity increases yields
Date:5/28/2008

at rotation. Differences were due to increased nitrogen availability and lowered weed competition with increasing crop rotation length and complexity. Crop rotation length and complexity did not affect soybean and wheat yields.

Dr. Michel Cavigelli, lead author of the study, stated, These research results show that longer, more complex crop rotations can help address the two most important production challenges in organic grain crop production: providing adequate nitrogen for crop needs and decreasing weed competition. This research should help organic farmers and those considering transitioning to organic farming select crop rotations best suited for the mid-Atlantic region. Since the FSP is one of only a handful of long-term cropping systems trials that includes diverse organic crop rotations, these results will also be of interest to organic farmers and those working with organic farmers nationwide.

Ongoing research at the USDA-ARS Sustainable Agricultural Systems Lab at BARC is designed to increase soil nitrogen availability and decrease weed pressure in organic grain crop rotations.
