Armstrong Research and Demonstration Farm
The Neely-Kinyon LTAR site was established in 1998 to study the long-term effects of organic production in Iowa. Treatments at the LTAR site, replicated four times in a completely randomized design, include the following rotations: conventional CornSoybean (C-S), organic Corn-SoybeanOats/Alfalfa (C-S-O/A), organic CornSoybean-Oats/Alfalfa-Alfalfa (C-S-O/A-A), and Soybean-Wheat with a red clover frostseeding (S-W/RC). Arapahoe winter wheat was planted on November 19, 2008, at 85 lb/acre and Cardinal red clover was frostseeded into the wheat plots on March 12, 2009, at a rate of 15.5 lb/acre. On April 16, 2009, Spur oats were underseeded with BR Blue Jay alfalfa at a rate of 90 lb/acre and 16 lb/acre, respectively. Following harvest of the organic corn plots in 2008, winter rye was no-till drilled at a rate of 75 lb/acre on November 10, 2008.
