Abstract
Studies to evaluate the effects on nitrification of 19 trace elements showed that all these elements inhibited nitrification of NH4+‐N added to soils. Results showed that the relative effectiveness of the trace elements in inhibition of nitrification depends on the soils. When the trace elements were compared to using 5 µmoles/g of soil, Ag(I), Hg(II), Cd(II), Ni(II), As(III), Cr(III), B(III), Al(III), Se(IV), and Mo(VI) were the most effective inhibitors (average inhibition >50%), and Mn(II) and Pb(II) the least effective (average inhibition Nitrobacter, causing accumulation of NO2−‐N in one of the soils used.Keywords
