Nitrogen Balance Studies For A Soil Cropped With Rice

Resoect to rice to wich about half a million hectars is allocated in Egypt and to wich about 238 thousand tons of different nitrogen fertilizers are applied.In addition balance sheet of potassium, which is on the contrary to nitrogen unsuscemical to gaseous losses through chemical and biochemical processes; is also worked out in the present study.this is recommended for judging the correctness of the correctness of the methodology involved through conductance of the nitrogen balance studies.
