Atmospheric deposition of inorganic nitrogen semi-arid grassland of Inner Mongolia, China

摘要: Due to increasing global demand fox crop production and energy use, more and more reactive nitrogen (Nx) has been generated and emitted to the environment. 11s a result, global atmospheric nitrogen (N) deposition has tripled since the industrial revolution and the ecological environment and human health have been harmed. In this study we measured dry and wet/bulk N deposition from July 2013 to December 2015 in a semi-arid grassland of Duolun County Inner Mongolia, China. The samples of dry and wet/bulk N deposition were collected monthly with a DELT11 (DEnudex fox Long Texm 1ltmosphexic sampling system and with Gxadko passive samplers and a precipitation gauge. The measured results show that the annual mean
