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== (詳細はJohann Friedrich Mayer was the first scientist to publish experiments on the use of gypsum as a fertilizer, but the mechanism that made it function as a fertilizer was contested by his contemporaries.〔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 Fruit Garden.'' 1840. p. 45.〕 In 1840, Liebig published what is now known as Liebig's law of the minimum. Liebig's law states that growth is not controlled by the total amount of resources available, but by the limiting factor. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term "agricultural science". The Hatch Act was driven by farmers' interest in knowing the constituents of early artificial fertilizer. Later on, the Smith-Hughes Act of 1917 shifted agricultural education back to its vocational roots, but the scientific foundation had been built.〔Hillison J. (1996). (The Origins of Agriscience: Or Where Did All That Scientific Agriculture Come From? ). ''Journal of Agricultural Education''.〕 After 1906, public expenditures on agricultural research in the US exceeded private expenditures for the next 44 years.〔Huffman WE, Evenson RE. (2006).
