Ransome Victory Plough
Ransome Victory Plough (American spelling "plow") is a type of single-share mouldboard plough commonly used throughout Southern Africa. Introduced into much of Southern Africa in the mid-1920s via European farmers and missionaries, it was quickly adopted over earlier, heavier models that required multiple spans (teams) of oxen. The Ransome Victory's relatively light weight allowed it to be pulled by a single span of oxen, allowing more smallholder farmers who owned fewer cattle to utilize the technology. The Ransome Victory Plough's most recognizable feature is the vertically adjustable pivot wheel in front of the ploughshare (as opposed to a cutting knife or wheel). This pivot wheel, combined with an offset tension bar to which the chain from the yoke is connected, causes the forward motion of oxen to force the blade into the soil. However, the tension bar is typically far weaker than the main plough beam, and is likely the first part of the plough to break. The difficulty of acces ...

Plough
A plough or plow ( US; both ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses, but in modern farms 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 use of farm ...

Smallholding
A smallholding or smallholder is a small farm operating under a small-scale agriculture model. Definitions vary widely for what constitutes a smallholder or small-scale farm, including factors such as size, food production technique or technology, involvement of family in labor and economic impact. Smallholdings are usually farms supporting a single family with a mixture of cash crops and subsistence farming. As a country becomes more affluent, smallholdings may not be self-sufficient, but may be valued for the rural lifestyle. As the sustainable food and local food movements grow in affluent countries, some of these smallholdings are gaining increased economic viability. There are an estimated 500 million smallholder farms in developing countries of the world alone, supporting almost two billion people. Small-scale agriculture is often in tension with industrial agriculture, which finds efficiencies by increasing outputs, monoculture, consolidating land under big agricu ...

Northern Rhodesia
Northern Rhodesia was a British protectorate in southern Africa, south central Africa, now the independent country of Zambia. It was formed in 1911 by Amalgamation (politics), amalgamating the two earlier protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia.''Commonwealth and Colonial Law'' by Kenneth Roberts-Wray, London, Stevens, 1966. P. 753 It was initially administered, as were the two earlier protectorates, by the British South Africa Company (BSAC), a chartered company, on behalf of the British Government. From 1924, it was administered by the British Government as a protectorate, under similar conditions to other British-administered protectorates, and the special provisions required when it was administered by BSAC were terminated.Northern Rhodesia Order in Council, 1924, S.R.O. 1924 No. 324, S.RO. & S.I.

Zambia
Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central Africa, Central, Southern Africa, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The nation's population of around 19.5 million is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following the arrival of European exploration of Africa, European explorers in the eighteenth century, the British colonised the r ...

Southern Province, Zambia
Southern Province is one of Zambia's ten provinces, and home to Zambia's premier tourist attraction, Mosi-oa-Tunya (Victoria Falls), shared with Zimbabwe. The centre of the province, the Southern Plateau, has the largest area of commercial farmland of any Zambian province, and produces most of the maize crop. The Zambezi River is the province's southern border, and Lake Kariba, formed by the Kariba Dam, lies along the province's south-eastern edge. The eastern border is the Kariba Gorge and Zambezi, and the north-east border is the Kafue River, forming its border with Lusaka Province. The Kafue Flats lie mostly within the province's northern border with Central Province. In the north west lies part of the famous Kafue National Park, the largest in Zambia. The south-western border with Western Province runs through the teak forests around Mulobezi which once supported a commercial timber industry and for which the Mulobezi Railway was built. The provincial capital is Choma. Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Degradation
Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil. Retrogression is primarily due to soil erosion and corresponds to a phenomenon where succession reverts the land to its natural physical state. Degradation is an evolution, different from natural evolution, related to the local climate and vegetation. It is due to the replacement of primary plant communities (known as climax vegetation) by the secondary communities. This replacement modifies the humus composition and amount, and affects the formation of the soil. It is directly related to human activity. Soil degradation may also be viewed as any change or ecological disturbance to the soil perceived to be deleterious or undesirable.Johnson, D.L., S.H. Ambrose, T.J. Bassett, M.L. Bowen, D.E.

Subsoiling
A subsoiler or flat lifter is a tractor-mounted farm implement used for deep tillage, loosening and breaking up soil at depths below the levels worked by moldboard ploughs, disc harrows, or rototillers. Most such tools will break up and turn over surface soil to a depth of , whereas a subsoiler will break up and loosen soil to twice those depths. The subsoiler is a tillage tool which will improve growth in all crops where soil compaction is a problem. In agriculture angled wings are used to lift and shatter the hardpan that builds up due to compaction. The design provides deep tillage, loosening soil deeper than a tiller or plough is capable of reaching. Agricultural subsoilers, according to the Unverferth Company, can disrupt hardpan ground down to depths. The subsoiler consists of three or more heavy vertical shanks (standards) mounted on a toolbar or frame with shear bolts. They can be operated at depths of or more. A ripper normally runs deep. Shanks are curved and have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ransomes, Sims & Jefferies
Ransomes, Sims and Jefferies Limited was a major British agricultural machinery maker also producing a wide range of general engineering products in Ipswich, Suffolk including traction engines, trolleybuses, ploughs, lawn mowers, combine harvesters and other tilling equipment. Ransomes also manufactured Direct Current electric motors in a wide range of sizes, and electric forklift trucks and tractors. They manufactured aeroplanes during the First World War. Their base, specially set up in 1845, was named Orwell Works. Ransomes' railway equipment business was hived off in 1869 with a different ownership as Ransomes & Rapier and based nearby at Waterside Ironworks. History 18th century The enterprise was started by Robert Ransome (1753–1830), who was born into a Quaker family in Norfolk, and became an apprentice to an ironmonger in Norwich. The Quaker values of frugal living, avoiding debt and keeping regular accounts served him well when he set up one of the first brass and ...

Ipswich
Ipswich () is a port town and borough in Suffolk, England, of which it is the county town. The town is located in East Anglia about away from the mouth of the River Orwell and the North Sea. Ipswich is both on the Great Eastern Main Line railway and the A12 road; it is north-east of London, east-southeast of Cambridge and south of Norwich. Ipswich is surrounded by two Areas of Outstanding Natural Beauty (AONB): Suffolk Coast and Heaths and Dedham Vale. Ipswich's modern name is derived from the medieval name ''Gippeswic'', probably taken either from an Anglo-Saxon personal name or from an earlier name given to the Orwell Estuary (although possibly unrelated to the name of the River Gipping). It has also been known as ''Gyppewicus'' and ''Yppswyche''. The town has been continuously occupied since the Saxon period, and is contested to be one of the oldest towns in the United Kingdom.Hills, Catherine"England's Oldest Town" Retrieved 2 August 2015.
