Furrow
A plough or ( US) plow (both pronounced ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an ''aratrum''. Celtic peoples first came to use wheeled ploughs in the Roman era. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting. Ploughing and cultivating soil evens the content of the upper layer of soil, where most plant feeder roots grow. Ploughs were initially powered by humans, but the u ...

Ard (plough)
The ard, ard plough, or scratch plough is a simple light plough without a mouldboard. It is symmetrical on either side of its line of draft and is fitted with a symmetrical share that traces a shallow furrow but does not invert the soil. It began to be replaced in China by the heavy carruca turnplough in the 1st century, and in most of Europe from the 7th century. In its simplest form it resembles a Hoe (tool), hoe, consisting of a ''draft-pole'' (either composite or a single piece) pierced with a nearly vertical, wooden, spiked ''head'' (or ''stock'') which is dragged through the soil by draft animals and very rarely by people. The ard-head is at one end a ''stilt'' (handle) for steering and at the other a ''share'' (cutting blade) which gouges the surface ground. More sophisticated models have a composite pole, where the section attached to the head is called the ''draft-beam'', and the share may be made of stone or iron. Some have a cross-bar for handles or two separate stilts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petty Plough
The Petty Plough was a steerable plough developed by brothers Frank and Herbert Petty of Doncaster, Victoria, Australia in the early 1930s. Background Frank and Herbert Petty were orchardists, growing apples, pears, lemons, Cherry, cherries and peaches. The entire orchard was cultivated. The Petty Plough was designed to plough between and around the fruit trees, working right up to the trees, eliminating the need for slow and tedious manual cultivation between the trees. Description The Petty Plough could be pulled by two horses or by a tractor.Collyer, Eric: Doncaster and Templestowe Historical Society Inc, newsletter, December 2009, Doncaster, Victoria. The Plough was fitted with lever and foot controls which operated four straight disc wheels. These were turned in and out of the trees as the operator desired. The wheels would sink into the ground about 2.5 inches, giving good control and preventing side slipping often associated with ploughing uneven surfaces. The cutting ...

Hoe (tool)
A hoe is an ancient and versatile agricultural and horticultural hand tool used to shape soil, remove weeds, clear soil, and harvest root crops. Shaping the soil includes piling soil around the base of plants ( hilling), digging narrow furrows ( drills) and shallow trenches for planting seeds or bulbs. Weeding with a hoe includes agitating the surface of the soil or cutting foliage from roots, and clearing the soil of old roots and crop residues. Hoes for digging and moving soil are used to harvest root crops such as potatoes. Types There are many kinds of hoes of varied appearances and purposes. Some offer multiple functions, while others have only a singular and specific purpose. There are two general types of hoe: draw hoes for shaping soil, and scuffle hoes for weeding and aerating soil. A draw hoe has a blade set at approximately a right angle to the shaft. The user chops into the ground and then pulls (draws) the blade towards them. Altering the angle of the hand ...

Harrow (tool)
In agriculture, a harrow is a farm implement used for surface tillage. It is used after ploughing for breaking up and smoothing out the surface of the soil. The purpose of harrowing is to break up clods and to provide a soil structure, called tilth, that is suitable for planting seeds. Coarser harrowing may also be used to remove weeds and to cover seed after sowing. Harrows differ from ploughs, which cut the upper 12 to 25 centimetre (5 to 10 in) layer of soil, and leave furrows, parallel trenches. Harrows differ from cultivators in that they disturb the whole surface of the soil, while a cultivator instead disturbs only narrow tracks between the crop rows to kill weeds. There are four general types of harrows: disc harrows, tine harrows (including spring-tooth harrows, drag harrows, and spike harrows), chain harrows, and chain-disk harrows. Harrows were originally drawn by draft animals, such as horses, mules, or oxen, or in some times and places by manual labourer ...

Tillage
Tillage is the agriculture, agricultural preparation of soil by mechanical wikt:agitation#Noun, agitation of various types, such as digging, stirring, and overturning. Examples of manual labour, human-powered tilling methods using hand tools include shoveling, pickaxe, picking, mattock work, hoe (tool), hoeing, and rake (tool), raking. Examples of working animal, draft-animal-powered or mechanization, mechanized work include ploughing (overturning with moldboards or chiseling with chisel shanks), rotary tiller, rototilling, rolling with cultipackers or other roller (agricultural tool), rollers, harrow (tool), harrowing, and cultivating with cultivator shanks (teeth). Tillage that is deeper and more thorough is classified as primary, and tillage that is shallower and sometimes more selective of location is secondary. Primary tillage such as ploughing tends to produce a rough surface finish, whereas secondary tillage tends to produce a smoother surface finish, such as that required ...

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...

Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a Trailer (vehicle), trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanization, mechanize agricultural tasks, especially (and originally) tillage, and now many more. List of agricultural machinery, Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the Agent (grammar), agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term "traction engine, traction motor" (1859).

Gothic Language
Gothic is an extinct language, extinct East Germanic languages, East Germanic language that was spoken by the Goths. It is known primarily from the ''Codex Argenteus'', a 6th-century copy of a 4th-century Bible translation, and is the only East Germanic language with a sizeable text corpus. All others, including Burgundian language (Germanic), Burgundian and Vandalic language, Vandalic, are known, if at all, only from proper names that survived in historical accounts, and from loanwords in other, mainly Romance languages, Romance, languages. As a Germanic language, Gothic is a part of the Indo-European languages, Indo-European language family. It is the earliest Germanic language that is attested in any sizable texts, but it lacks any modern descendants. The oldest documents in Gothic date back to the fourth century. The language was in decline by the mid-sixth century, partly because of the military defeat of the Goths at the hands of the Franks, the elimination of the Goths ...

Swedish Language
Swedish ( ) is a North Germanic languages, North Germanic language from the Indo-European languages, Indo-European language family, spoken predominantly in Sweden and parts of Finland. It has at least 10 million native speakers, making it the Germanic_languages#Statistics, fourth most spoken Germanic language, and the first among its type in the Nordic countries overall. Swedish, like the other North Germanic languages, Nordic languages, is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Age. It is largely mutually intelligible with Norwegian language, Norwegian and Danish language, Danish, although the degree of mutual intelligibility is dependent on the dialect and accent of the speaker. Standard Swedish, spoken by most Swedes, is the national language that evolved from the Central Swedish dialects in the 19th century, and was well established by the beginning of the 20th century.

Old Norse
Old Norse, also referred to as Old Nordic or Old Scandinavian, was a stage of development of North Germanic languages, North Germanic dialects before their final divergence into separate Nordic languages. Old Norse was spoken by inhabitants of Scandinavia and their Viking expansion, overseas settlements and chronologically coincides with the Viking Age, the Christianization of Scandinavia, and the consolidation of Scandinavian kingdoms from about the 8th to the 15th centuries. The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid- to late 14th century, ending the language phase known as Old Norse. These dates, however, are not precise, since written Old Norse is found well into the 15th century. Old Norse was divided into three dialects: Old West Norse (Old West Nordic, often referred to as ''Old Norse''), Old East Norse (Old East Nordic), and Old Gutnish. Old West Norse and O ...

Old High German
Old High German (OHG; ) is the earliest stage of the German language, conventionally identified as the period from around 500/750 to 1050. Rather than representing a single supra-regional form of German, Old High German encompasses the numerous West Germanic languages, West Germanic dialects that had undergone the set of sound change, consonantal changes called the High German consonant shift, Second Sound Shift. At the start of this period, dialect areas reflected the territories of largely independent tribal kingdoms, but by 788 the conquests of Charlemagne had brought all OHG dialect areas into a single polity. The period also saw the development of a stable linguistic border between German and Gallo-Romance languages, Gallo-Romance, later French language, French. Old High German largely preserved the synthetic language, synthetic inflectional system inherited from its ancestral Germanic forms. The eventual disruption of these patterns, which led to the more analytic language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
