Südheide Nature Park
The Südheide Nature Park ("Southern Heath Nature Park", German: ''Naturpark Südheide'') is a large protected area of forest and heathland in the southern part of the Lüneburg Heath in North Germany. It has been designated as a protected nature park since 1964. Location The Südheide Nature Park is roughly in area and lies in the southern part of the Lüneburg Heath, in the northeastern part of Celle district, beginning a few kilometres north of Celle itself. From there it stretches northwards, between the towns of Bergen to the west, Faßberg to the north and Weyhausen and Steinhorst to the east. The other towns in the nature park are Eschede, Hermannsburg, Müden (Örtze), Unterlüß, Eldingen and, on the edge of the park, Winsen an der Aller. The borders of the nature park are not identical with the term ''Südheide'' used in local parlance. That refers to the region south of a line from Munster to Uelzen to Gifhorn. Northwest of the Südheide Nature Park is the Lüneb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winsen An Der Aller
Winsen an der Aller () or Winsen (Aller) is a town in the district of Celle in the German state of Lower Saxony. Geography Winsen has around 12,900 inhabitants and lies on the southern perimeter of the Lüneburg Heath, on the banks of the Aller, somewhat to the west of its tributary, the Örtze and about 15 km northwest of Celle. As well as the town itself, the borough of Winsen also includes the villages of Bannetze, Meißendorf, Stedden, Südwinsen, Thören, Walle and Wolthausen. History The name of the town is derived from ''Wynhausen'' (''Wyn'' = ''Weideland'' or meadow). Winsen's church is dedicated to John the Baptist. Because all villages with churches named after this patron saint appeared around 800 it is suspected that this was also when Winsen was founded. Today Winsen is a favourite local recreation and holiday area and, since 1975, has been recognised officially as a climatic health resort (''Luftkurort'').

Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family (biology), family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or Trinomial nomenclature, trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kieselgur
Diatomaceous earth (), diatomite (), or kieselgur/kieselguhr is a naturally occurring, soft, siliceous sedimentary rock that can be crumbled into a fine white to off-white powder. It has a particle size ranging from more than 3 μm to less than 1 mm, but typically 10 to 200 μm. Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder, and has a low density as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80–90% silica, with 2–4% alumina (attributed mostly to clay minerals), and 0.5–2% iron oxide. Diatomaceous earth consists of the fossilized remains of diatoms, a type of hard-shelled microalgae. It is used as a filtration aid, mild abrasive in products including metal polishes and toothpaste, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics and rubber, anti-block in plastic films, porous support for chemical ...

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 ...

Geest (topography)
Geest is a type of landform, slightly raised above the surrounding countryside, that occurs on the plains of Northern Germany, the Northern Netherlands and Denmark. It is a landscape of sandy and gravelly soils formed as a glacial outwash plain and now usually mantled by a heathland vegetation on the glacial deposits left behind after the last ice age during the Pleistocene epoch.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, p. 214. . The term ''geest'' is a substantivisation of the Low German adjective ''güst'', which means "dry and infertile". It is an Old Drift landscape, characterised by the sandy depositions of the Ice Age. In the depressions between the raised flats are wet meadows and, where drainage is poor, bogs. Geest lands are made up of moraines and sandurs. They are almost always next to flat marshlands, the geest being higher and better protected against flood but, compared to the marsh, with poor soil for agriculture. Where th ...

End Moraine
A terminal moraine, also called end moraine, is a type of moraine that forms at the Glacier terminus, terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose Rock (geology), rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when ...

Ground Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Proven ...

Outwash Plain
An outwash plain, also called a sandur (plural: ''sandurs''), sandr or sandar, is a plain formed of glaciofluvial deposits due to meltwater outwash at the terminus of a glacier. As it flows, the glacier grinds the underlying rock surface and carries the debris along. The meltwater at the snout of the glacier deposits its load of sediment over the outwash plain, with larger boulders being deposited near the terminal moraine, and smaller particles travelling further before being deposited. Sandurs are common in Iceland where geothermal activity accelerates the melting of ice flows and the deposition of sediment by meltwater. Formation Sandurs are found in glaciated areas, such as Svalbard, Kerguelen Islands, and Iceland. Glaciers and icecaps contain large amounts of silt and sediment, picked up as they erode the underlying rocks when they move slowly downhill, and at the snout of the glacier, meltwater can carry this sediment away from the glacier and deposit it on a broad p ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called ''interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for t ...
