A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. [1]

Rather than the practice which developed in the Old World of sowing a field with a single crop, pre-historic American ...
The history of the Haber process begins with the invention of the Haber process at the dawn of the twentieth century. The process allows the economical fixation of atmospheric dinitrogen in the form of ammonia, which in turn allows for the industrial synthesis of various explosives and nitrogen fertilizers, and is probably the most important industrial process developed during the twentieth ...
Ammonia from plants built during World War II to make explosives became available for making fertilizers, leading to a permanent decline in real fertilizer prices and expanded use.
