  • The best way you can manage its long-term impacts is by better matching nitrogen inputs to the crop requirements and reducing the amount of surplus nitrogen (ie the difference between nitrogen inputs and nitrogen taken up by the crop.
  • While past studies show elevated rates of inorganic nitrogen (n) deposition in cities, less is known about atmospheric inputs of organic n, organic carbon (c), and organic and inorganic phosphorus (p), all of which can affect ecosystem processes, water quality, and air quality further, the effect of the tree canopy on amounts and forms of nutrients reaching urban ground surfaces is not well.
