    Inorganic nitrogen (N) dissolved in groundwater could be lost for crop production through downward and sideway movements of groundwater, resulting in lower yields and profit margins above costs. Differences in leaching between N sources can effectively be utilised to reduce the risk of N leaching.

    Most crops will perform best when receiving 75 % nitrate–N and 25% ammonium-N while 100 % ammonium-N would be toxic (Adriaanse, 1990). LAN consists of 50% nitrate-N and 50% ammonium-N. Shortly after application of LAN, part of the ammonium-N will be converted to nitrate-N.
