摘      要：Nitrogen(N)is an important nutrient that is essential for all life on Earth.Although N accounts for 78%of the total atmospheric volume,it cannot be used by plants or animals unless it is converted to reactive nitrogen(Nr)such as ammonia(NH3)or related nitrogenous compounds.The supply of reactive N has been the bottleneck in food production for centuries.Since 1913,the Haber-Bosch process has greatly improved the ability of humans to produce N fertilizers from atmospheric N.The rapid growth of the world s population since 1960 is closely related to the increase in food production caused by the increased use of N fertilizers[1].Population growth further leads to increases in N-fixing crop cultivation,animal husbandry expansion,and fossil fuel con sumption.
