Abstract

The nitrification inhibitor was added to a submerged soil system to check loss of the ammonified N through nitrification denitrification. The presence of nitrapyrin significantly raised the recovery of NH+ 4‐N released during the 2 weeks of incubation at 30°C for soils having near neutral to alkaline pH probably by preventing nitrification. The levels of mineralizable NH+ 4 obtained using a modified version of the incubation method were comparable with those obtained by incubation of the submerged soil samples under an atmosphere of N2. Our results emphasize the importance of exclusion of air from the soil‐water system during waterlogged incubation of soils for preventing the loss of ammonified N by nitrification and denitrification. It is suggested that this can be achieved either by incubation of the soils under an atmosphere of inert gases such as N2 or possibly by the use of a nitrification inhibitors such as Nitrapyrin
