Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
1) Due to the inorganic nature of the substance standard testing systems are not applicable.
2) In unsterilized soil, ammonium sulfate is mineralized fairly rapidly, and subsequently nitrified. Nitrification and de-nitrification processes also occur naturally in streams and rivers, as well as in many secondarysewage treatment processes (WHO, 1986,OECD 2007).
3) Ammonia from ammonium sulfate decomposition can be released from soils,especially if applied fertiliser is not covered by soil. Ammonium remaining in soil is largely adsorbed onto negatively charged clayparticles, and will undergo nitrification and denitrification as part ofthe nitrogen cycle and be taken up by plants via nitrogen fixation (WHO,1986). Sulfate can also be retained in soil, both by incorporation into organic matter (e.g. as sulfate esters of humic acids) and adsorbed to soil particles such as hydrous iron and aluminum sesquioxides (EPA, 2002).

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
