Harcourt Morgan
John Harcourt Alexander Morgan (August 31, 1867 – August 25, 1950) was a Canadian-American entomologist, educator, and agricultural expert, who served as president of the University of Tennessee from 1919 until 1934. In 1933, he was appointed to the inaugural board of the Tennessee Valley Authority, with which he remained until 1948, including three years (1938–1941) as chairman. In both capacities, he promoted a philosophy known as "the common mooring," which stressed a harmonious relationship between man and the environment, and consistently worked to introduce more efficient and less destructive farming techniques in the Tennessee Valley.Milton Klein,John Harcourt Alexander Morgan" ''Tennessee Encyclopedia of History and Culture'', 2009.

Crop Rotation
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds. Growing the same crop in the same place for many years in a row, known as monocropping, gradually depletes the soil of certain nutrients and selects for a highly competitive pest and weed community. Without balancing nutrient use and diversifying pest and weed communities, the productivity of monocultures is highly dependent on external inputs. Conversely, a well-designed crop rotation can reduce the need for synthetic fertilizers and herbicides by better using ecosystem services from a diverse set of crops. Additionally, crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience. History Agriculturalists have long recognized that suitable rotations — such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austin Peay
Austin Peay (June 1, 1876 – October 2, 1927) was an American politician who served as the 35th governor of Tennessee from 1923 to 1927. He was the state's first governor since the Civil War to win three consecutive terms and the first to die in office. Prior to his election as governor, he served two terms in the Tennessee House of Representatives (1901–1905). As governor, Peay consolidated government agencies, overhauled the tax code, improved higher education, expanded the state highway system, and converted a $3 million state debt into a budget surplus.Dan Pierce,Austin Peay" ''Tennessee Encyclopedia of History and Culture'', 2009.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tom Rye
Thomas Clarke Rye (June 2, 1863September 12, 1953) was an American politician who served as the 32nd governor of Tennessee from 1915 to 1919. An ardent supporter of prohibition of alcoholic beverages, he helped reunify the state's Democratic Party, which had been divided over the issue for nearly a decade. Rye is perhaps best remembered for enacting the "Ouster Law," which was aimed at curbing the power of political boss E. H. Crump.Anne-Leslie Owens,Thomas Clarke Rye" ''Tennessee Encyclopedia of History and Culture'', 2009. Retrieved: 4 December 2012.

Land-grant University
A land-grant university (also called land-grant college or land-grant institution) is an institution of higher education in the United States designated by a state to receive the benefits of the Morrill Land-Grant Acts, Morrill Acts of 1862 and 1890. Signed by Abraham Lincoln in 1862, the first Morrill Act began to fund educational institutions by granting federally controlled land (economics), land to the states for them to sell, to raise funds, to establish and Financial endowment, endow "land-grant" colleges. The mission of these institutions as set forth in the 1862 act is to focus on the teaching of practical agriculture, science, military science, and engineering—although "without excluding other scientific and classical studies"—as a response to the industrial revolution and changing social class. This mission was in contrast to the historic practice of higher education concentrating on a liberal arts curriculum. A 1994 expansion gave land-grant status to several trib ...

Union (American Civil War)
During the American Civil War, the Union, also known as the North, referred to the United States led by President Abraham Lincoln. It was opposed by the secessionist Confederate States of America (CSA), informally called "the Confederacy" or "the South". The Union is named after its declared goal of preserving the United States as a constitutional union. "Union" is used in the U.S. Constitution to refer to the founding formation of the people, and to the states in union. In the context of the Civil War, it has also often been used as a synonym for "the northern states loyal to the United States government;" in this meaning, the Union consisted of 20 free states and five border states. The Union Army was a new formation comprising mostly state units, together with units from the regular U.S. Army. The border states were essential as a supply base for the Union invasion of the Confederacy, and Lincoln realized he could not win the war without control of them, especially Maryla ...

East Tennessee
East Tennessee is one of the three Grand Divisions of Tennessee defined in state law. Geographically and socioculturally distinct, it comprises approximately the eastern third of the U.S. state of Tennessee. East Tennessee consists of 33 counties, 30 located within the Eastern Time Zone and three counties in the Central Time Zone, namely Bledsoe, Cumberland, and Marion. East Tennessee is entirely located within the Appalachian Mountains, although the landforms range from densely forested mountains to broad river valleys. The region contains the major cities of Knoxville and Chattanooga, Tennessee's third and fourth largest cities, respectively, and the Tri-Cities, the state's sixth largest population center. During the American Civil War, many East Tennesseans remained loyal to the Union even as the state seceded and joined the Confederacy. Early in the war, Unionist delegates unsuccessfully attempted to split East Tennessee into a separate state that would remain as part ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Grand Divisions Of Tennessee
The Grand Divisions are three geographic regions in the U.S. state of Tennessee, each constituting roughly one-third of the state's land area, that are geographically, culturally, legally, and economically distinct. The Grand Divisions are legally recognized in the state constitution and state law and are represented on the Flag of Tennessee by the flag's three prominent stars. The Grand Divisions, East, Middle, and West Tennessee, are sometimes referred to as "three states of Tennessee" or "the three Tennessees". Definitions The three Grand Divisions, East, Middle, and West Tennessee, are formally defined in state law at Tennessee Code Annotated Title 4, Chapter 1, Part 2 ("Grand Divisions and State Capital") as the "eastern, middle, and western" Grand Divisions of the state. The law lists the counties in each region. The boundary between East Tennessee and Middle Tennessee is on the Cumberland Plateau, which was a major barrier to travel and commerce during much of the ...

Phosphate
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one or two protons gives the dihydrogen phosphate ion and the hydrogen phosphate ion ion, respectively. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

Agricultural Lime
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate. Additional chemicals vary depending on the mineral source and may include calcium oxide. Unlike the types of lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide), powdered limestone does not require lime burning in a lime kiln; it only requires milling. All of these types of lime are sometimes used as soil conditioners, with a common theme of providing a base to correct acidity, but lime for farm fields today is often crushed limestone. Historically, liming of farm fields in centuries past was often done with burnt lime; the difference is at least partially explained by the fact that affordable mass-production-scale fine milling of stone and ore relies on technologies developed since the mid-19th century. Some effects of agricultural lime on soil are: * it increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
