Abstract

The Neely-Kinyon long term agroecological research site (LTAR) 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-Oat/Alfalfa, (C-S-O/A), organic Corn-Soybean-Oat/Alfalfa-Alfalfa (C-S-O/A-A), and organic Corn-Soybean-Corn-Oat/Alfalfa (C-S-C-O/A). Oat/Alfalfa plots were field cultivated March 29. On April 4, Reins oats were underseeded with Viking 3800 alfalfa (Albert Lea Seed) at a rate of 90 lbs./acre and 15 lbs./acre, respectively. Plots were cultipacked on the same day as planting. Following harvest of the organic corn plots in 2021, winter rye was drilled at a rate of 75 lbs./acre on October 18, 2021.
