Abstract: Nitrogen is a pivotal component of proteins making 60% dry matter of plant cell. It is reported deficient in most of the soils of world. An incubation study was conducted to assess Ntransformations under aerobic and submerged conditions using organic amendment. Maximum oxidation of NH 4 was observed in organically amended soils followed by control treatment. Nitrification is NH 4 to NO 3 conversion process was observed to be lowest under submerged condition. With passage of incubation time NO 3 content in organically amended and control treatment get enhanced while under flooded conditions least declining trend in NH 4 content was observed from start to ending days. Least N losses were observed in organically amended aerated soil.
