Abstract

The Neely-Kinyon LTAR was established in 1998 to study the long-term effects of organic production in Iowa. Treatments, replicated four times, at the LTAR site include the following rotations: conventional Corn-Soybean (C-S), organic Corn-Soybean-Oats/Alfalfa (C-S-O/A), organic Corn-Soybean-Oats/Alfalfa-Alfalfa (CS-O/A-A), and soybean-wheat (S-W). Variety selection and planting methods were as follows: Pioneer 34M94 corn was planted at a depth of 1.75 in. as untreated seed at a rate of 32,000 seeds/acre in the organic plots and as treated seed at a rate of 30,200 seeds/acre in conventional plots on May 14, 2002. Northrup King 2412 soybeans were planted at a depth of 2 in. in organic and conventional plots at a rate of 200,000 seeds/acre on May 29, 2002.
