Fig. 7. Total integrated emissions of NO, N2O, and NO + N2O from anhydrous ammonia (AA), urea ammonium nitrate (UAN), and broadcast urea (BU) treated plots under conventional tillage (CT) and no tillage (NT) during 2004. Values indicate mean (±standard error, n = 3) NO and NO + N2O emissions. For each component (NO, or NO + N2O), bars with the same letter designation are not significantly different (p > 0.05).
