Reduced ,forms of nitrogen,, particularly ,ammonia, (NH 3), are vital to life. Before the early 1900s, all reduced N came from biological ,nitrogen, fixation by microbes. This landscape changed in the early 1900s with the invention by Haber and Bosch of an industrial process to reduce N 2 to NH 3 (N 2 + 3H 2 ⇄ 2NH 3).

Each box represents a stock or pool. Circles represent data inputs to the model. Flows ,of nitrogen, between stocks are identified with arrows, accompanied by first-order rate constants, k. Clouds indicate a loss ,of nitrogen, from the system. Total ,ammonia nitrogen, is modelled as ,ammonia, (NH 3) and ammonium (NH 4 +).
