Abstract
1. With a recurrent supply of particulate organic matter, the formation of ammonia, nitrite and nitrate may take place simultaneously. The process which predominates will depend upon the stage at which the new organic matter is introduced. 2. The nature of the suspended particulate matter is of considerable importance in determining the total duration of the decomposition cycle, but the level of its original concentration is only a minor determining factor. 3. There is some evidence of a "growth-promoting" factor, normally effective in the decomposition cycle, but which can be destroyed by high temperature.
