Why was the haber process important?

Answer 1

The Haber process began to produce ammonia to be oxidized to Nitrite and Nitrate and then made into nitric acid, a basic reagent for explosives. It is now used to make ammonia for ammonium nitrate for fertilizer. The Haber process uses the chemical reaction N2 + 3 H2 --> 2 NH3.

Answer 2

A better question is Why IS the haber process important? It is involved in nitrogen fixation and Ammonification which is of course used in fertilizer therefore without the haber process the majority of our crops would have poor soil due to lack of fertilizer and humanity would eventually die from the food shortage
