Nitrification and denitrification in submerged Maahas clay soil

A laboratory experiment showed that the oxidized layer of submerged soil has high nitrifying activity. Denitrification was active in soil below the soil surface. Tracer technique indicated that the nitrification and the subsequent denitrification of ammonium sulfate was most active in the layer about 2 cm below the soil surface, and that the activities extended to a depth of about 5 cm, Nitrification Inhibitors reduced the nitrogen lost through nitrification and subsequent denitrification.
