Additional information
Ammonium in soil is largely adsorbed onto positively charged clayparticles, and will undergo nitrification and denitrification as part of the 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).
