History Of Agricultural Science
The history of agricultural science is a sub-field of the history of agriculture which looks at the scientific advancement of techniques and understanding of agriculture. Early study of organic production in botanical gardens was continued in with agricultural experiment stations in several countries. Fertilizer is a major contribution to agriculture history increasing the fertility of the soil and minimizing nutrient loss. Scientific study of fertilizer was advanced significantly in 1840 with the publication ''Die organische Chemie in ihrer Anwendung auf Agrikulturchemie und Physiologie'' (Organic Chemistry in Its Applications to Agriculture and Physiology) by Justus von Liebig. One of Liebig's advances in agricultural science was the discovery of nitrogen as an essential plant nutrient. Fertilizer The first method of soil nourishment utilized compost. Composting used rotten organic materials to replenish the soil of its nutrients and dates back to tenth and twelfth century Ara ...

Luigi Alamanni, La Coltivazione
Luigi (; ) is a character (arts), character created by Japanese video game designer Shigeru Miyamoto. Part of Nintendo's Mario (franchise), ''Mario'' franchise, he is a kind-hearted, cowardly Italian plumber, and the younger fraternal twin brother and sidekick of Mario. Like his brother, Luigi's distinctive characteristics include his large nose and mustache, overalls, green hat, and high-pitched, exaggerated Italian accent. Luigi first appeared in ''Mario Bros.'', a 1983 platformer, platform game, in which he was originally designed as a palette swap of Mario with a green color scheme; Luigi has since appeared in multiple games and other media throughout the ''Mario'' franchise, in which developed a personality and style of his own. As his role in the ''Mario'' franchise progressed, Luigi evolved into a physically distinct character, and become the main protagonist of ''Mario Is Missing!, Mario is Missing!'' and the ''Luigi's Mansion'' series. Charles Martinet voiced Luigi f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limiting Factor
A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. A factor not limiting over a certain domain of starting conditions may yet be limiting over another domain of starting conditions, including that of the factor. Overview The identification of a factor as limiting is possible only in distinction to one or more other factors that are non-limiting. Disciplines differ in their use of the term as to whether they allow the simultaneous existence of more than one limiting factor (which may then be called "co-limiting"), but they all require the existence of at least one non-limiting factor when the terms are used. There are several different possible scenarios of limitation when more than one factor is present. The first scenario, called ''single limitation'' occurs when only one factor, the one with maximu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Science
Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists. History In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulfate) as a fertilizer.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. In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smith–Hughes Act
The Smith–Hughes National Vocational Education Act of 1917 was an act of the United States Congress that promoted vocational education in "agriculture, trades and industry, and homemaking," and provided federal funds for this purpose. As such, it is the basis both for the promotion of vocational education, and for its isolation from the rest of the curriculum in most school settings. The act was based largely on a report and recommendation from Charles Allen Prosser's ''Report of the National Commission on Aid to Vocational Education''. Woodlawn High School (Woodlawn, Virginia) became the first public secondary school in the United States to offer agricultural education classes under the Smith–Hughes Act. Of all the vocational subjects mentioned, home economics is the only vocational subject that the act recognized for girls. Securing passage in 1917 Supporters of vocational education were very well organized under the leadership of Charles A. Prosser and Senator Hoke Smi ...

Hatch Act Of 1887
The Hatch Act of 1887 (ch. 314, , enacted 1887-03-02, et seq.) gave federal funds, initially $15,000 each, to state land-grant colleges in order to create a series of agricultural experiment stations, as well as pass along new information, especially in the areas of soil minerals and plant growth. The bill was named for Congressman William Hatch, who chaired the House Committee of Agriculture at the time the bill was introduced. State agricultural stations created under this act were usually connected with those land-grant state colleges and universities founded under the Morrill Act of 1862, with few exceptions. Many stations founded under the Hatch Act later became the foundations for state cooperative extension services under the Smith–Lever Act of 1914. Congress amended the act in 1955 to add a formula that uses rural and farm population factors to allocate the annual appropriation for agricultural experiment stations among the states. Under the 2002 farm bill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nobel Prize
The Nobel Prizes ( ; ; ) are awards administered by the Nobel Foundation and granted in accordance with the principle of "for the greatest benefit to humankind". The prizes were first awarded in 1901, marking the fifth anniversary of Alfred Nobel, Alfred Nobel's death. The original Nobel Prizes covered five fields: Nobel Prize in Physics, physics, Nobel Prize in Chemistry, chemistry, Nobel Prize in Physiology or Medicine, physiology or medicine, Nobel Prize in Literature, literature, and Nobel Peace Prize, peace, specified in Nobel's will. A sixth prize, the Nobel Memorial Prize in Economic Sciences, Prize in Economic Sciences, was established in 1968 by Sveriges Riksbank (Sweden's central bank) in memory of Alfred Nobel. The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields.Nobel Prize#Shalev69, Shalev, p. 8.

Haber Process
The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the ammonia production, production of ammonia. It converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using finely divided iron metal as a catalyst: \ce \qquad This reaction is exothermic but disfavored in terms of entropy because four equivalents of reactant gases are converted into two equivalents of product gas. As a result, high pressures and temperatures that are not too high are needed to Le_Chatelier's_principle, drive the reaction forward. The German chemists Fritz Haber and Carl Bosch developed the process in the first decade of the 20th century, and its improved efficiency over existing methods such as the Birkeland–Eyde process, Birkeland-Eyde and Frank–Caro process, Frank-Caro processes was a major advancement in the industrial production of ammonia. The Haber process can be combined with steam reforming to produce ammonia with just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Bosch
Carl Bosch (; 27 August 1874 – 26 April 1940) was a German chemist and engineer and Nobel Laureate in Chemistry. He was a pioneer in the field of high-pressure industrial chemistry and founder of IG Farben, at one point the world's largest chemical company. He also developed the Haber–Bosch process, important for the large-scale synthesis of fertilizers and explosives. It is estimated that one-third of annual global food production uses ammonia from the Haber–Bosch process, and that this supports nearly half of the world's population. In addition, he co-developed the so-called Bosch-Meiser process for the industrial production of urea. Biography Early years Carl Bosch was born in Cologne to a successful gas and plumbing supplier. His father was Carl Friedrich Alexander Bosch (1843–1904) and his uncle was Robert Bosch, who pioneered the development of the spark plug and founded the multinational company Bosch. Carl, trying to decide between a career in metallu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fritz Haber
Fritz Jakob Haber (; 9 December 1868 – 29 January 1934) was a German chemist who received the Nobel Prize in Chemistry in 1918 for his invention of the Haber process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas. This invention is important for the large-scale synthesis of fertilizers and Explosive material, explosives. It is estimated that a third of annual global food production uses ammonia from the Haber–Bosch process, and that this food supports nearly half the world's population. For this work, Haber has been called one of the most important scientists and industrial chemists in human history. Haber also, along with Max Born, proposed the Born–Haber cycle as a method for evaluating the lattice energy of an ionic solid. Haber, a known German nationalist, is also considered the "father of chemical warfare" for his years of pioneering work developing and Chlorine#Use as a weapon, weaponizing chlorine and other poisonous gases during ...
