Effects of trace elements on nitrogen mineralisation in soils

摘要: Abstract Studies to evaluate the effects on nitrogen mineralisation of 19 trace elements showed that all inhibit mineral production in soils. Results relative effectiveness inhibition depends soil. When were compared by using 5 μmole/g soil, Ag(I) and Hg(II) most effective [with ≥ Hg(II)] Co(II), As(III), Se(IV), As(V), W(VI) least mineralisation. Other inhibited soils were: Cu(II), Cd(II), Pb(II), Mn(II), Fe(II), Zn(II), Ni(II), Sn(II), Cr(III), Fe(III), Al(III) B(III), V(IV) Mo(VI); their degrees varied four studied. Ag(I), Hg(II), Al(III), Se(IV) nitrification, causing accumulation ammonium-N some used.
