than in a flow through test.
2) This reference also cites other papers which give ammonia
losses from fertilisers and liquid sludges applied to soils of
up to 60%. The ammonia volatilisation is dependent upon the pH
of the soil and mode of application, with subsurface
application having greatly reduced ammonia loss from soil.
Surface crop residue may also be important in some cases.
Result:
Only 1% or less of the applied ammonium sulfate was
captured as ammonia, after 16 days at 25 °C.
Test condition: In a laboratory study using seived soils hydrated to field
capacity, static ammonia traps were used to capture ammonia
volatilising from ammonium sulfate added to two soils of pH
6.8 and 5.6, with and without a straw cover.

Fugacity model cannot be used due to inorganic nature of the
substance. Based on the physical-chemical properties of the
substance water is probably the preferred compartment.
