Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vicia
''Vicia'' is a genus of over 240 species of flowering plants that are part of the legume family (Fabaceae), and which are commonly known as vetches. Member species are native to Europe, North America, South America, Asia and Africa. Some other genera of their subfamily Faboideae also have names containing "vetch", for example the vetchlings (''Lathyrus'') or the milk-vetches (''Astragalus''). The broad bean (''Vicia faba'') is sometimes separated in a monotypic genus ''Faba''; although not often used today, it is of historical importance in plant taxonomy as the namesake of the order Fabales, the Fabaceae and the Faboideae. The tribe Vicieae in which the vetches are placed is named after the genus' current name. Among the closest living relatives of vetches are the lentils (''Lens'') and the true peas (''Pisum''). Use by humans Bitter vetch ('' V. ervilia'') was one of the first domesticated crops. It was grown in the Near East about 9,500 years ago, starting perhaps ev ...

Vicia Villosa
''Vicia villosa'', known as the hairy vetch, fodder vetch or winter vetch, is a plant native to some of Europe and western Asia. It is a legume, grown as a forage crop, fodder crop, cover crop, and green manure. Although non-native, it occurs in all US states and is considered invasive by some states, such as Alaska, Florida, Georgia, Kansas, Michigan, Minnesota, Oregon, and Washington state — as well as in Japan and some parts of Europe where it is not native. It is also found in most Canadian provinces. Hairy vetch is very similar to tufted vetch (''Vicia cracca''), the most noticeable difference being that tufted vetch has a smooth stem. Several subspecies are recognized: * ''Vicia villosa'' ssp. ''ambigua'' (Guss.) Kerguelen (= ssp. ''elegantissima'', ssp. ''pseudocracca'') * ''Vicia villosa'' ssp. ''eriocarpa'' (Hausskn.) P.W.Ball * ''Vicia villosa'' ssp. ''microphylla'' (d'Urv.) P.W.Ball * ''Vicia villosa'' ssp. ''varia'' (Host) Corb. (= ssp. ''dasycarpa'') * ''Vicia vil ...

Winter Wheat
Winter wheat (usually ''Triticum aestivum'') are strains of wheat that are planted in the autumn to germinate and develop into young plants that remain in the vegetative phase during the winter and resume growth in early spring. Classification into spring wheat versus winter wheat is common and traditionally refers to the season during which the crop is grown. For winter wheat, the physiological stage of heading (when the ear first emerges) is delayed until the plant experiences vernalization, a period of 30 to 60 days of cold winter temperatures (0° to 5 °C; 32–41 °F). Winter wheat is usually planted from September to November (in the Northern Hemisphere) and harvested in the summer or early autumn of the next year. In some places (e.g. Chile) a winter-wheat crop fully 'completes' in a year's time before harvest. Winter wheat usually yields more than spring wheat. So-called "facultative" wheat varieties need shorter periods of vernalization time (15–30 days ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nurse Crop
Nurse crops are a subtype of nurse plants, facilitating the growth of other species of plants. The term is used primarily in agriculture, but also in forestry. Cover crops are a type of nurse crop. Agriculture In agriculture, a nurse crop is an annual crop used to assist in establishment of a perennial crop. The widest use of nurse crops is in the establishment of legumaceous plants such as alfalfa, clover, and trefoil. Occasionally, nurse crops are used for establishment of perennial grasses. Nurse crops reduce the incidence of weeds, prevent erosion, and prevent excessive sunlight from reaching tender seedlings. Often, the nurse crop can be harvested for grain, straw, hay, or pasture. Oats are the most common nurse crop, though other annual grains are also used. Nurse cropping of tall or dense-canopied plants can protect more vulnerable species through shading or by providing a wind break. However, if ill-maintained, nurse crops can block sunlight from reaching seedlings. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Vetch
''Vicia sativa'', known as the common vetch, garden vetch, tare or simply vetch, is a nitrogen-fixing leguminous plant in the family Fabaceae. It is likely native to North Africa, Western Asia and Europe, but is now naturalized in temperate and subtropical regions worldwide. Although considered a weed when found growing in a cultivated grainfield, this hardy plant is often grown as a green manure, livestock fodder or rotation crop. More than per year of ''Vicia sativa'' is grown in Australia. Description ''Vicia sativa'' is a sprawling annual herb, with hollow, four-sided, hairless to sparsely hairy stems which can reach two meters in maximum length. The leaves are stipulate, alternate and compound, each made up of 3–8 opposite pairs of linear, lance-shaped, oblong, or wedge-shaped, needle-tipped leaflets up to long. Each compound leaf ends in a branched tendril. The pea-like flowers occur in the leaf axils, solitary or in pairs. The flower corolla is long and bright ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Green Manure
In agriculture, a green manure is a crop specifically produced to be incorporated into the soil while still green. Typically, the green manure's biomass is incorporated with a plow or disk, as is often done with (brown) manure. The primary goal is to add organic matter to the soil for its benefits. Green manuring is often used with legume crops to add nitrogen to the soil for following crops, especially in organic farming, but is also used in conventional farming. Functions Green manures usually perform multiple functions that include soil improvement and soil protection: * Leguminous green manures such as clover and vetch contain nitrogen-fixing symbiotic bacteria in root nodules that fix atmospheric nitrogen in a form that plants can use. This performs the vital function of fertilization. :Depending on the species of cover crop grown, the amount of nitrogen released into the soil lies between 40 and 200 pounds per acre. With green manure use, the amount of nitrogen that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cover Crop
In agriculture, cover crops are plants that are planted to cover the soil rather than for the purpose of being harvested. Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosysteman ecological system managed and shaped by humans. Cover crops may be an off-season crop planted after harvesting the cash crop. They may grow over winter. Cover crops are nurse crops in that they increase the survival of the main crop being harvested. Soil erosion Although cover crops can perform multiple functions in an agroecosystem simultaneously, they are often grown for the sole purpose of preventing soil erosion. Soil erosion is a process that can irreparably reduce the productive capacity of an agroecosystem. Cover crops reduce soil loss by improving soil structure and increasing infiltration, protecting the soil surface, scattering raindrop energy and reducing the velocity of the movement of water over the so ...

Western Asia
Western Asia, West Asia, or Southwest Asia, is the westernmost subregion of the larger geographical region of Asia, as defined by some academics, UN bodies and other institutions. It is almost entirely a part of the Middle East, and includes Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian Highlands, the Levant, the island of Cyprus, the Sinai Peninsula, and partly the Caucasus Region (Transcaucasia). The region is considered to be separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. Western Asia covers an area of , with a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Frederick Gray
Samuel Frederick Gray (10 December 1766 – 12 April 1828) was a British botanist, mycologist, and pharmacologist. He was the father of the zoologists John Edward Gray and George Robert Gray. Background He was the son of Samuel Gray, a London seedsman. He received no inheritance and, after failing to qualify for medicine, turned to medical and botanical writing. He married Elizabeth Forfeit in 1794 and moved to Walsall, Staffordshire, where he established an assay office before he moved back to London in 1800. He set up an apothecary business in Wapping, which failed within a few years. Then, he seems to have maintained himself by writing and lecturing. Medical writings Gray wrote a ''Supplement to the Pharmacopoeia'', published in 1818 with several subsequent editions. In 1819, he became co-editor of the ''London Medical Repository'', to which he contributed many articles on medical, botanical, and other topics. He published, in 1823, ''The Elements of Pharmacy'' and, in 1828, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
