Sanborn Field
Sanborn Field is an agricultural experiment field, located on the University of Missouri campus in Columbia, Missouri. Established in 1888, it was the first facility in the United States intended to measure erosion and run-off for differing crops and agricultural practices. Work at Sanborn Field was influential in the establishment of soil conservation policy in the United States. The field was designated a National Historic Landmark in 1964. The field is currently managed as part of the Agricultural Extension Station under the university's School of Natural Resources. Description Sanborn Field is located on the east side of the University of Missouri campus, on land purchased by the state for the university campus during the 1870s. It is roughly in size, and is bounded by Bouchelle Avenue, Connaway Hall, Rollins Street, and College Avenue. Once in a rural area, the field is now surrounded by built-up portions of Columbia. It is subdivided into plots measuring . History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia, Missouri
Columbia is a city in the U.S. state of Missouri. It is the county seat of Boone County and home to the University of Missouri. Founded in 1821, it is the principal city of the five-county Columbia metropolitan area. It is Missouri's fourth most-populous and fastest growing city, with an estimated 126,254 residents in 2020. As a Midwestern college town, Columbia has a reputation for progressive politics, persuasive journalism, and public art. The tripartite establishment of Stephens College (1833), the University of Missouri (1839), and Columbia College (1851), which surround the city's Downtown to the east, south, and north, has made the city a center of learning. At its center is 8th Street (also known as the Avenue of the Columns), which connects Francis Quadrangle and Jesse Hall to the Boone County Courthouse and the City Hall. Originally an agricultural town, education is now Columbia's primary economic concern, with secondary interests in the healthcare, insuranc ...

Fertilizer
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal fro ...

University Of Missouri Campus
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Tetracycline
Tetracycline, sold under various brand names, is an oral antibiotic in the tetracyclines family of medications, used to treat a number of infections, including acne, cholera, brucellosis, plague, malaria, and syphilis. Common side effects include vomiting, diarrhea, rash, and loss of appetite. Other side effects include poor tooth development if used by children less than eight years of age, kidney problems, and sunburning easily. Use during pregnancy may harm the baby. It works by inhibiting protein synthesis in bacteria. Tetracycline was patented in 1953 and came into commercial use in 1978. It is on the World Health Organization's List of Essential Medicines. Tetracycline is available as a generic medication. Tetracycline was originally made from bacteria of the genus ''Streptomyces''. Medical uses Spectrum of activity Tetracyclines have a broad spectrum of antibiotic action. Originally, they possessed some level of bacteriostatic activity against almost all medi ...

Chlortetracycline
Chlortetracycline (trade name Aureomycin, Lederle Laboratories) is a tetracycline antibiotic, the first tetracycline to be identified. It was discovered in 1945 at Lederle Laboratories under the supervision of scientist Yellapragada Subbarow and Benjamin Minge Duggar. Duggar identified the antibiotic as the product of an actinomycete he cultured from a soil sample collected from Sanborn Field at the University of Missouri. The organism was named ''Streptomyces aureofaciens'' and the isolated drug, Aureomycin, because of their golden color. It is on the World Health Organization's List of Essential Medicines. Medical uses A combination cream with triamcinolone acetonide is available for the treatment of infected allergic dermatitis in humans. In veterinary medicine, chlortetracycline is commonly used to treat conjunctivitis in cats, dogs and horses. It is also used to treat infected wounds in cattle, sheep and pigs, and respiratory tract infections in calves, pigs and chickens ...

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 — ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manure
Manure is organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces; other sources include compost and green manure. Manures contribute to the Soil fertility, fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungus, fungi and other organisms in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web. History According to a Byzantine tradition attributed to Cassianus Bassus pig dung was generally not usable as fertilizer, except for almond trees. Similar views recorded by Columella were unrelated to the Islamic taboos of later centuries, though the medieval Al-Andalus, Andalusian writer Ibn Bassal and some later writers from Yemen also recorded negative effects of pig dung "burning" plants. Ibn Bassal described a sort of mixed manure with straw or sweeping mixed in as ', implying that was not composed of only manure. ...

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Na ...
