OR:

The history of fertilizer has largely shaped political, economic, and social circumstances in their traditional uses. Starting in the 20th century, chemically synthesized, synthetic fertilizers have radically reshaped environmental conditions.


History

Egyptians, Romans, Babylonians, and early Germans all are recorded as using minerals and/or manure to enhance the productivity of their farms. The use of wood ash as a field treatment became widespread.Heinrich W. Scherer "Fertilizers" in Ullmann's Encyclopedia of Industrial Chemistry, 2000, Wiley-VCH, Weinheim. Although it was previously thought that the concept of fertilizer use may have only dated back 2,000 to 3,000 years, it is now believed that early farmers were using manure to fertilize their crops as long as 8,000 years ago. In the Andes, they used

for at least 1500 years, before the European countries started importing it in the 19th century for their increasing demands due to the industrial revolution. In this century, "guano" was taken in large quantities from Peru and Chile (and later also from Namibia and other areas) to Europe and the USA, motivating the
War of the Pacific The War of the Pacific (), also known by War of the Pacific#Etymology, multiple other names, was a war between Chile and a Treaty of Defensive Alliance (Bolivia–Peru), Bolivian–Peruvian alliance from 1879 to 1884. Fought over Atacama Desert ...
between Peru, Chile and Bolivia. Fish was used as fertilizer, at least as early as 1620.


Key men in Europe and their inventions


Johann Fredrich Mayer

Johann Friedrich Mayer (1719–1798) was the first to present to the world a series of experiments upon it the relation of

to agriculture, and many chemists have followed him in the 19th century. Early 19th century however a great variety of opinion remained with regard to its mode of operation, for example:John Armstrong, Jesse Buel. ''A Treatise on Agriculture, The Present Condition of the Art Abroad and at Home, and the Theory and Practice of Husbandry. To which is Added, a Dissertation on the Kitchen and Garden.'' 1840. p. 45. * The French agronomist Victor Yvart (1763–1831) believed that the action of gypsum is exclusively the effect of the sulphuric acid, which enters into its composition; and founds this opinion upon the fact that the ashes of turf, which contain sulphate of iron and sulphate of alumina, have the same action upon vegetation as gypsum. * The French agronomist Charles Philibert de Lasteyrie (1759–1849), observing that plants whose roots were nearest the surface of the soil were most acted upon by plaster, concludes that gypsum takes from the atmosphere the elements of vegetable life, and transmits them directly to plants. *
Louis Augustin Guillaume Bosc Louis Augustin Guillaume Bosc (or Louis-Augustin Bosc d'Antic) (29 January 1759 – 10 July 1828) was a French botanist, invertebrate zoologist, and entomologist. Biography Bosc was born in Paris, the son of Paul Bosc d’Antic, a medical doctor ...
intimates that the septic quality of gypsum (which he takes for granted) best explains its action on vegetation; but this opinion is subverted by the experiments of Davy. *

found that, of two parcels of minced veal, the one mixed with gypsum, the other left by itself, and both exposed to the action of the sun, the latter was the first to exhibit symptoms of putrefaction. Davy's own belief on this subject is, that it makes part of the food of vegetables, is received into the plant, and combined with it. Mayer also promote new regimes of
