Other uses that are made of chemicals used as fertilizers are discussed, as well as some of the environmental impacts of fertilizer manufacture and use.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eLess than two hundred years ago, naturally occurring ores and organic plant and animal wastes were used as fertilizer. There was not enough of these products to meet demand. People were malnourished.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThe first chemically altered phosphorus (P) fertilizer to be used was single superphosphate (SSP). In Australia, superphosphate was first used in wheat grown in rotation with legume-based pastures. From the late 1960s high analysis ammonium phosphate fertilizers replaced superphosphate in cropping. Superphosphate continued to be used on pasture.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThe first nitrogen (N) fertilizer to be used in Australia was byproduct ammonium sulfate from gasworks and the steel industry. Ammonium sulfate was later synthesized by reacting ammonia produced through the Haber Bosch process with sulfuric acid. The Haber Bosch process is regarded as one of the most, if not the most important technological development of the 20th century. In the 1970s urea overtook ammonium sulfate as the most popular nitrogen fertilizer.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eIn 1850, there were 1.25 billion people on earth. In 2025, that number exceeded eight billion. Australia's population is 27.5 million. About three-quarters of Australia's rural produce is exported. The nation feeds and clothes a population of around 100 million. This would not be possible without advances in chemical engineering and agricultural science.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbout the Author\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003ci\u003eKuhn, Garry:\u003c\/i\u003e\u003c\/b\u003e - Garry Kuhn grew up on a farm in southern Queensland, Australia, and studied Rural Technology at the Agricultural College at Gatton. He joined the fertilizer industry in 1974 working in research, sales, marketing, administrative and managerial roles until his retirement 43 years later in 2017. In this book, he recounts the history of the fertilizer industry, in Australia and abroad, and some of his own experiences.","brand":"Tellwell Talent","offers":[{"title":"Default Title","offer_id":52179983106322,"sku":"9781834187129","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_ef518a05-b16f-4176-a079-000fe058ea2b.jpg?v=1775642205","url":"https:\/\/surprise-castle.myshopify.com\/products\/famine-to-feast-how-fertilizers-transformed-global-food-security-and-shaped-agricultural-progress-in-australia-and-beyond-9781834187129","provider":"Surprise Castle","version":"1.0","type":"link"}
