The ISU Neely-Kinyon Farm, Greenfield, Iowa, Long-Term Agroecological Research (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 Corn-Soybean (C-S), organic Corn-Soybean-Oats/Alfalfa (C-S-O/A), organic Corn-Soybean-Oats/Alfalfa-Alfalfa (C-S-O/A-A), and organic Corn-Soybean-Corn-Oats/Alfalfa (C-S-C-O/A). Oat/alfalfa plots were field cultivated April 11, 2018. On April 12, Deon oats were underseeded with Viking 3800 alfalfa (Albert Lea Seed, Albert Lea, MN) at a rate of 90 lb/acre and 15 lb/acre, respectively. Plots were cultipacked on the same day as planting. Following harvest of the organic corn plots in 2017, winter rye was no-till drilled at a rate of 75 lb/acre November 10, 2017.
