    Release of N2O from N-fertilized corn fields

      Graphical Abstract
      • Abstract
    • Nitrous oxide emissions were measured inthree corn plots by different N-fertilized treatments from Juneto september in 1993.During the growing season of corn,theaverages of N2O fluxes from control, urea-treated,and ma-nure-treated plots were 8.5±2.2,18.9±11.7 and 15.4±5.9μg N/m2·h,respectively. Calculation is made on the lossrate of fertilizer as N2O. The emission coefficients of urea andorganic manure were 0.19%and 0.12%,respectively.
