Effect of iron oxide on nitrification in two agricultural

Iron (Fe) affects soil nitrogen (N) cycling processes both in anoxic and oxic environments. The role of Fe in soil N transformations including nitrification mineralization and immobilization is influenced by redox activity which is regulated by soil pH. The effect of Fe minerals particularly oxides on soil N transformation processes depends on soil pH with Fe oxide often stimulating
