The Fens
The Fens or Fenlands in eastern England are a naturally marshy region supporting a rich ecology and numerous species. Most of the fens were drained centuries ago, resulting in a flat, dry, low-lying agricultural region supported by a system of drainage channels and man-made rivers (Ditch, dykes and drains) and automated pumping stations. There have been unintended consequences to this reclamation, as the land level has continued to sink and the dykes have been built higher to protect it from flooding. ''Fen'' is the local term for an individual area of marshland or former marshland. It also designates the type of marsh typical of the area, which has pH, neutral or alkaline water and relatively large quantities of dissolved minerals, but few other plant nutrition, plant nutrients. The Fens are a National Character Area, based on their landscape, biodiversity, geodiversity and economic activity. The Fens lie inland of the Wash, and are an area of nearly in the south east of L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Region
A natural region (landscape unit) is a basic geographic unit. Usually, it is a region which is distinguished by its common natural features of geography, geology, and climate. From the ecological point of view, the naturally occurring flora and fauna of the region are likely to be influenced by its geographical and geological factors, such as soil and water availability, in a significant manner. Thus most natural regions are homogeneous ecosystems. Human impact can be an important factor in the shaping and destiny of a particular natural region. Main terms The concept "natural region" is a large basic geographical unit, like the vast boreal forest region. The term may also be used generically, like in alpine tundra, or specifically to refer to a particular place. The term is particularly useful where there is no corresponding or coterminous official region. The Fens of eastern England, the Thai highlands, and the Pays de Bray in Normandy, are examples of this. Others mig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley Civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainag ...

Agricultural Land Classification
The Agricultural Land Classification system forms part of the planning system in England and Wales. It classifies agricultural land in five categories according to versatility and suitability for growing crops. Grades Source: *Grade 1, 2 and 3a, are referred to as 'Best and Most Versatile' land, and enjoy significant protection from development. *Grade 4 and 5 are described as ''poor quality agricultural land'' and ''very poor quality agricultural land'' Wales In November 2017, the Welsh Government launched thPredictive Agricultural Land Classification Map This is the first update since the 1970s and replaces thProvisional Agricultural Land Classification Mapfor Wales. Importantly it distinguishes between ALC Sub-grades 3a and 3b. The Welsh Government is undertaking the first update to the Predictive Agricultural Land Classification Map between 2018 and 2020.Frequently Asked Questionsdescribes how the quality of farm land is graded and what this grade means for landowners.

Arable Land
Arable land (from the , "able to be ploughed") is any land capable of being ploughed and used to grow crops.''Oxford English Dictionary'', "arable, ''adj''. and ''n.''" Oxford University Press (Oxford), 2013. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition: A more concise definition appearing in the Eurostat glossary similarly refers to actual rather than potential uses: "land worked (ploughed or tilled) regularly, generally under a system of crop rotation". In Britain, arable land has traditionally been contrasted with pasturable land such as heaths, which could be used for sheep-rearing but not as farmland. Arable land is vulnerable to land degradation and some types of un-arable land can be enriched to create useful land. Climate change and biodiversity loss are driving pressure on arable land. By country According to the Food and Agriculture Organization of the United Nations, in 2013, the world's arable land amo ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Axholme
The Isle of Axholme is an area of Lincolnshire, England, adjoining South Yorkshire and the East Riding of Yorkshire. It is located between Scunthorpe and Gainsborough, both of which are in the traditional West Riding of Lindsey, and Doncaster, in South Yorkshire. Description The name ''Isle'' is given to the area since, prior to the area being drained by the Dutchman Cornelius Vermuyden in the 17th century, each town or village was built on areas of dry, raised ground in the surrounding marshland. The River Don used to flow to the north and west (it has since been diverted), dividing the Isle from Yorkshire; the River Idle separates the Isle from Nottinghamshire; and the River Trent separates the Isle from the rest of Lincolnshire. Three towns developed here: Epworth, Crowle and Haxey. The boundaries of the Isle of Axholme usually match with those of the ancient '' wapentake'' of Epworth and its 17 communities as listed in the Domesday Book of 1086: Belton, Crowle, ...

Huntingdonshire
Huntingdonshire (; abbreviated Hunts) is a local government district in Cambridgeshire, England, which was historically a county in its own right. It borders Peterborough to the north, Fenland to the north-east, East Cambridgeshire to the east, South Cambridgeshire to the south-east, Central Bedfordshire and Bedford to the south-west, and North Northamptonshire to the west. Huntingdonshire, along with Peterborough, Fenland and East Cambridgeshire, serves as the area of land between The Midlands and East Anglia and is often considered to carry a mixed identity for this reason. It is also sometimes considered an informal county. The district had a population of 180,800 at the 2021 census, and has an area of . After St Neots (33,410), the largest towns are Huntingdon (25,428), St Ives, Cambridgeshire, St Ives (16,815), and Yaxley, Cambridgeshire, Yaxley (9,174 in 2011).

National Character Area
A National Character Area (NCA) is a natural subdivision of England based on a combination of landscape, biodiversity, geodiversity and economic activity. There are 159 National Character Areas and they follow natural, rather than administrative, boundaries. They are defined by Natural England, the UK government's advisors on the natural environment. NCA profiles As part of its responsibilities in delivering the Natural Environment White Paper, Biodiversity 2020 and the European Landscape Convention, Natural England is revising its National Character Area profiles to make environmental evidence and information easily available to a wider audience. Revised profiles for all 159 NCAs were published in September 2014. The new NCAs are being published in a rolling program and can be found on the Natural England website. NCAs are areas that share similar landscape characteristics, and which follow natural lines in the landscape rather than administrative boundaries, making them a good ...

Plant Nutrition
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von Liebig's law of the minimum. The total essential plant nutrients include seventeen different elements: carbon, oxygen and hydrogen which are absorbed from the air, whereas other nutrients including nitrogen are typically obtained from the soil (exceptions include some parasitic or carnivorous plants). Plants must obtain the following mineral nutrients from their growing medium: * The macronutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulfur (S), magnesium (Mg), carbon (C), hydrogen (H), oxygen (O) * The micronutrients (or trace minerals): iron (Fe), boron (B), chlorine (Cl), manganese (Mn), zinc (Zn), copper (Cu), mo ...

Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The Geology, geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock (geology), rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral or may be an aggregate (geology), aggregate of two or more different types of minerals, spaci ...
