| Mobility : |
When spilled on soil, the liquid form will spread on the
surface and penetrate into the soil at a rate dependent on the
soil type and its water content (HSDB 1999).

| Other information of degradation : |
Ammonium, (aerobic transformation):
One group of bacteria oxidizes ammonium to nitrite, another
group oxides nitrite to nitrate.
Average biodegradation rate in
wastewater plant (20 °C) 52 g N/kg d.s./day.
Nitrate (anaerobic transformation into N2, N2O, NH3):
Biodegradation rate in waste water plant (20 °C) 70 g N/kg
d.s./day (IUCLID 1996).
Aquatic: Ammonium nitrate is a nutrient in water.
Spills of
ammonium nitrate may cause massive algal bloom in static waters
and affects local species population balance in the aquatic
environment (HSDB 1999).
