human interaction with the nitrogen cycle is primarily due to?
the agricultural sector
human impact on the nitrogen cycle is diverse. agricultural and industrial nitrogen (n) inputs to the environment currently exceed inputs from natural n fixation. as a consequence of anthropogenic inputs, the global nitrogen cycle (fig. 1) has been significantly altered over the past century. global atmospheric nitrous oxide (no) mole fractions have increased from a pre-industrial value of ~270 nmol/mol to ~319 nmol/mol in 2005. human activities account for over one-third of no emissions, most of which are due to the agricultural sector. this article is intended to give a brief review of the history of anthropogenic n inputs, and reported impacts of nitrogen inputs on selected terrestrial and aquatic ecosystems.
human impact on the nitrogen cycle
the nitrogen cycle is of particular interest to ecologists because nitrogen availability can affect the rate of key ecosystem processes, including primary production and decomposition. human activities such as fossil fuel combustion, use of artificial nitrogen fertilizers, and release of nitrogen in wastewater have dramatically altered the global nitrogen cycle. human modification of global nitrogen cycle can negatively affect the natural environment system and also human health.
