Interpretive Summary:

Technical Abstract: Nutrient leaching and greenhouse gas emission are two of the primary environmental impacts of crop production. These processes have been studied at great length separately, but few integrated studies of leaching and greenhouse gas emission have been conducted. We measured nutrient leaching and greenhouse gas emissions simultaneously in field plots under continuous corn and corn-soybean rotation. Fertilizer treatments were urea and anhydrous ammonia at equivalent N rates. Effects of fertilizer form and crop rotation on nitrogen and phosphorous leaching will be presented. Impacts on the emission of carbon dioxide, methane, and nitrous oxide will also be presented.
