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 .
John T. Arundel and Co. was engaged in Pacific trading of phosphates, copra, and pearl shell. While working in the company's Sydney office in 1899 Ellis determined that a large rock from Nauru being used as a doorstop was rich in phosphate. Following the discovery Ellis traveled to Ocean Island and Nauru and confirmed the discovery.
Phosphorus must have been awe-inspiring to an alchemist: it was a product of man, and seeming to glow with a "life force" that did not diminish over time (and did not need re-exposure to light like the previously discovered Bologna Stone). Brand kept his discovery secret, as alchemists of the time did, and worked with the phosphorus trying ...

Under the food production regime in developed countries, shortages of rock phosphate could lead to shortages of inorganic fertilizer, which could in turn reduce the global food production. [ 95 ] Economists have pointed out that price fluctuations of rock phosphate do not necessarily indicate peak phosphorus, as these have already occurred due ...
But since 1948, all phosphate deposits mined in the US have been sedimentary deposits. However, a small amount of phosphate was produced in the 1970s, as a byproduct of iron mining in Missouri. [12] Most phosphate mining is of sedimentary phosphorite, a phosphorus-rich deposit formed under shallow marine conditions. However, a number of US ...
5-2 million years ago: Hominids shift away from the consumption of nuts and berries to begin the consumption of meat. [1] [2]A hearth with cooking utensils. 2.5-1.8 million years ago: The discovery of the use of fire may have created a sense of sharing as a group.
The process was subsequently improved by reacting phosphate coprolites with sulfuric acid. Subsequently, other phosphate-rich deposits such as phosphorite were discovered and used. Soluble phosphate is an essential nutrient for all plants, and the availability of superphosphate revolutionised agricultural productivity.
