Short summary
The effect of Fe oxide on N transformation processes were different in soils as a function of pH. 15N-labelled ammonium and nitrate were used separately to determine N transformation rates combined with Fe oxide (ferrihydrite) addition. Iron oxide addition stimulated net nitrification in the low-pH soil (pH 5.1), while the opposite occurred in the high-pH soil (pH 7.8). Fe oxide increased NH3-N availability by stimulating N mineralization and inhibiting N immobilization at low pH.
