The Centennial Rotation - Cotton/Corn/Soybean Systems Effects on Nutrient Uptake and Removal in the Midsouth (2004-2011)

The Centennial Rotation that was initiated in 2004 continues to evaluate cotton/corn/soybean rotation systems with respect to yield, nutrient uptake, and nutrient removal.  Estimates are made each year based on the yields of the crops being grown. This poster will serve as the companion poster for one submitted to look at yields and value.  Information will be summarized for the first eight years of the study.  Each crop in a rotation system is grown each year.  The 2-year rotations have completed four cycles, the 3-year rotations are in the middle of the third cycle, and the 4-year rotations have completed two cycles.
