caption_attribution_description: English: A schematic of an ammonia generator system. This system was designed by Bill Holmgren (see http://www.permaculture.org/nm/images/uploads/Permaculture_Techniques.pdf ), and was intented for fertilization of crops. The titanium oxide is a catalyst, so the system does not run out of resources to generate the fertiliser.
context_page_description: The history of fertilizer has largely shaped political, economic, and social circumstances in their traditional uses. Subsequently, there has been a radical reshaping of environmental conditions following the development of chemically synthesized fertilizers.
