Convertible Husbandry
Convertible husbandry, also known as alternate husbandry or up-and-down husbandry, is a method of farming whereby strips of arable farmland were temporarily converted into grass pasture, known as leys. These remained under grass for up to 10 years before being ploughed under again, while some eventually became permanent pasturage. It was a process used during the 16th century through the 19th century by "which a higher proportion of land was used to support increasing numbers of livestock in many parts of England."Broad, John, "Alternate Husbandry and Permanent Pasture in the Midlands, 1650 – 1800", '' The Agricultural History Review'', Vol. 28, No. 2, pg 77-78, British Agricultural Society; 1980. Its adoption was an important component of the British Agricultural Revolution.Kerridge, Eric, ''The Agricultural Revolution'', Taylor and Francis US; 1967, pg 40. Ley farming, a similar system of growing fodder on fallow plots of arable land, remains in use today. Description Con ... [...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, milk, egg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midlands
The Midlands (also referred to as Central England) are a part of England that broadly correspond to the Kingdom of Mercia of the Early Middle Ages, bordered by Wales, Northern England and Southern England. The Midlands were important in the Industrial Revolution of the 18th and 19th centuries. They are split into the West Midlands and East Midlands. The region's biggest city, Birmingham often considered the social, cultural, financial and commercial centre of the Midlands, is the second-largest city and metropolitan area in the United Kingdom. Symbolism A saltire (diagonal cross) may have been used as a symbol of Mercia as early as the reign of Offa. By the 13th century, the saltire had become the attributed arms of the Kingdom of Mercia. The arms are blazoned ''Azure, a saltire Or'', meaning a gold (or yellow) saltire on a blue field. The saltire is used as both a flag and a coat of arms. As a flag, it is flown from Tamworth Castle, the ancient seat of the Mercian Kings, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Townshend, 2nd Viscount Townshend
Charles Townshend, 2nd Viscount Townshend, (; 18 April 167421 June 1738) was an English Whig statesman. He served for a decade as Secretary of State for the Northern Department, 1714–1717, 1721–1730. He directed British foreign policy in close collaboration with his brother-in-law, prime minister Robert Walpole. He was often known as Turnip Townshend because of his strong interest in farming turnips and his role in the British Agricultural Revolution. Early life Townshend was the eldest son of Sir Horatio Townshend, 3rd Baronet, who was created Baron Townshend in 1661 and Viscount Townshend in 1682. The old Norfolk family of Townshend, to which he belonged, is descended from Sir Roger Townshend (d. 1493) of Raynham, who acted as legal advisor to the Paston family, and was made a justice of the common pleas in 1484. His descendant, another Sir Roger Townshend (c. 1543–1590), had a son Sir John Townshend (1564–1603), a soldier, whose son, Sir Roger Townshend (158 ...

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] |

Clover
Clover or trefoil are common names for plants of the genus ''Trifolium'' (from Latin ''tres'' 'three' + ''folium'' 'leaf'), consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate (rarely quatrefoiled; see four-leaf clover), monofoil, bifoil, cinquefoil, hexafoil, septfoil, etcetera, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include ''Melilotus'' (sweet clover) and '' Medicago'' ( alfalfa or Calv ...

Legume
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and green peas, which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Middle Ages
The Late Middle Ages or Late Medieval Period was the period of European history lasting from AD 1300 to 1500. The Late Middle Ages followed the High Middle Ages and preceded the onset of the early modern period (and in much of Europe, the Renaissance). Around 1300, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it had been before the calamities. Along with depopulation came social unrest and endemic warfare. France and England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict, the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was temporarily shattered by the Western Schism. Collectively, those events are sometimes called the Crisis of the Late Middle Ages. Despite the crises, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop Yields
In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer, the creation of better farming tools, new methods of farming and improved crop varieties, have improved yields. The higher the yield and more intensive use of the farmland, the higher the productivity and profitability of a farm; this increases the well-being of farming families. Surplus crops beyond the needs of subsistence agriculture can be sold or bartered. The more grain or fodder a farmer can produce, the more draft animals such as horses and oxen could be supported and harnessed for labour and production of manure. Increased crop yields also means fewer hands are needed on farm, freeing them for industry and commerce. This, in turn, led to the formation and growth of cities, which then translated into an increased demand for foodstuffs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stock Breeding
Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products. It includes day-to-day care, selective breeding, and the raising of livestock. Husbandry has a long history, starting with the Neolithic Revolution when animals were first domesticated, from around 13,000 BC onwards, predating farming of the first crops. By the time of early civilisations such as ancient Egypt, cattle, sheep, goats, and pigs were being raised on farms. Major changes took place in the Columbian exchange, when Old World livestock were brought to the New World, and then in the British Agricultural Revolution of the 18th century, when livestock breeds like the Dishley Longhorn cattle and Lincoln Longwool sheep were rapidly improved by agriculturalists, such as Robert Bakewell, to yield more meat, milk, and wool. A wide range of other species, such as horse, water buffalo, llama, rabbit, and guinea pig, are used as livestock in some pa ...

Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on clim ...
