Seed Drill
A seed drill is a device used in agriculture that sows seeds for crops by positioning them in the soil and burying them to a specific depth while being dragged by a tractor. This ensures that seeds will be distributed evenly. The seed drill sows the seeds at the proper seeding rate and depth, ensuring that the seeds are covered by soil. This saves them from being eaten by birds and animals, or being dried up due to exposure to the sun. With seed drill machines, seeds are distributed in rows; this allows plants to get sufficient sunlight, nutrients, and water from the soil. Before the introduction of the seed drill, most seeds were planted by hand broadcasting, an imprecise and wasteful process with a poor distribution of seeds and low productivity. Use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times. The use of seed drill saves time and labor. Some machines for metering out seeds for planting are called planters. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sowing
Sowing is the process of planting seeds. An area or object that has had seeds planted in it will be described as a sowed or sown area. Plants which are usually sown Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals. Depth of sowing In sowing, little if any soil is placed over the seeds, as seeds can be generally sown into the soil by maintaining a planting depth of about 2-3 times the size of the seed. Sowing types and patterns For hand sowing, several sowing types exist; these include: * Flat sowing * Ridge sowing * Wide bed sowing Several patterns for sowing may be used together with these types; these include: * Regular rows * Rows that are in ...

Crop Yield
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 foodstuf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bourgault Air Seeder & Paralink Hoe Drill
Bourgault (); is a predominantly Breton surname derived from Old French but ultimately of Germanic French origin. "Bourg" is from the Frankish *burg meaning town, fortress, or castle and "ault" (-aud) from the Frankish *wald meaning power, mastery, or rule. Philologically, a plurality of Frankish (Franconian) words with the phoneme "w" were changed to gu/ga/gau while developing into nascent old French (e.g. Frankish *werra "war"= "guerre" in Old French, *want "gauntlet"= "gant", and *walha "foreigner/Celt"= " gaulois"). See: Gauthier. Thus, the name means roughly "master of fortification," indicating a position along the lines of a castellan or burgrave. The toponymic "gau" may be significant by dint of the historiographical connotations of the name's meaning. Archaic variants and cognates of the name, used then as an occupational given name, are attested to as early as the 6th century and are found in Fredegar's chronicle although the validity of this source, notwithstand ...

Seed-counting Machine
Seed counting machines count seeds for research and packaging purposes. The machines typically provide total counts of seeds or batch sizes for packaging. Background The first seed counters were developed to count legumes and other seeds which were large. Traditionally, the seed packaging industry packed seeds by weight but sold them by number. In order to assure the correct quantity of seeds, the distributors added a safety margin to the packed weight, like a bakers' dozen. This safety margin increased cost. By counting the seeds, the margin of error could be reduced and so costs reduced. History Originally people counted seeds by hand, or used a trip board. The first seed-counting machine was the vibratory mechanical seed counter. Modern day electronic seed counters are faster and more accurate. A color-image-based seed sorter was developed which can sort various things by their color. In 1929 the US Bureau of Plant Industry worked with several seed companies to perfe ...

Soil Loss
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.

Machine Tool
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the work piece and provide a guided movement of the parts of the machine. Thus, the relative movement between the workpiece and the cutting tool (which is called the toolpath) is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or " freehand". It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. The precise definition of the term ''machine tool'' varies among users, as discussed below. While all machine tools are "machines that help people to make things", not all factory machines are machine tools. Today machi ...

British Agricultural Revolution
The British Agricultural Revolution, or Second Agricultural Revolution, was an unprecedented increase in agricultural production in Britain arising from increases in labour and land productivity between the mid-17th and late 19th centuries. Agricultural output grew faster than the population over the hundred-year period ending in 1770, and thereafter productivity remained among the highest in the world. This increase in the food supply contributed to the rapid growth of population in England and Wales, from 5.5 million in 1700 to over 9 million by 1801, though domestic production gave way increasingly to food imports in the nineteenth century as the population more than tripled to over 35 million. Using 1700 as a base year (=100), agricultural output per agricultural worker in Britain steadily increased from about 50 in 1500, to around 65 in 1550, to 90 in 1600, to over 100 by 1650, to over 150 by 1750, rapidly increasing to over 250 by 1850.Broadberry et al 2008, p. ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Bologna
Bologna (, , ; egl, label=Emilian language, Emilian, Bulåggna ; lat, Bononia) is the capital and largest city of the Emilia-Romagna region in Northern Italy. It is the seventh most populous city in Italy with about 400,000 inhabitants and 150 different nationalities. Its Metropolitan City of Bologna, metropolitan area is home to more than 1,000,000 people. It is known as the Fat City for its rich cuisine, and the Red City for its Spanish-style red tiled rooftops and, more recently, its leftist politics. It is also called the Learned City because it is home to the oldest University of Bologna, university in the world. Originally Etruscan, the city has been an important urban center for centuries, first under the Etruscans (who called it ''Felsina''), then under the Celts as ''Bona'', later under the Romans (''Bonōnia''), then again in the Middle Ages, as a free municipality and later ''signoria'', when it was among the List of largest European cities in history, largest Euro ...

Venetian Senate
The Senate ( vec, Senato), formally the ''Consiglio dei Pregadi'' or ''Rogati'' (, la, Consilium Rogatorum), was the main deliberative and legislative body of the Republic of Venice. Establishment The Venetian Senate was founded in 1229, or less likely shortly before that date. Its creation was both the result of the rising predominance of the aristocratic element in the Republic, and of the necessity to govern a territory that was much more extensive than the earlier Dogado and still expanding at a rapid rate. The Senate originated as a select committee of sixty men, chosen by the Great Council, to deliberate on decrees concerning taxation, commerce, foreign policy, and military operations, instead of the far larger, and more unwieldy, Great Council. Hence, it was initially named the council of the or , while the name of 'Senate' was only applied to it in the late 14th century, under the influence of Renaissance humanism.
