A Pictorial Essay on Rapeseed and Canola
Updated on November 7, 2015 Greensleeves Hubs moreContact Creator INTRODUCTION
The nation of England is understood for – because the music ‘Jerusalem’ tells us – its green and nice land. Farmland makes up about 70% of the land space, and traditionally features neat squares and rectangles of crops, fairly smaller than those in the nice corn belt of America, and normally lined with lengthy hedgerows of trees and shrubs. The fields – the squares and rectangles – are seen to best impact from a high vantage point, from the rolling hills of the Chilterns, or the Malverns, the Cotswolds or the Pennines. And historically the fields have been a patchwork of subtle shades of greens and browns and pale straw colours in keeping with the crop which is being grown. Sometimes a field of the pale blue of linseed flax, or uncultivated fields speckled with the purple of the wild area poppy, would break the pattern of the greens and browns.
But in latest decades, a new colour has been added to the mix. A really bright colour. Every year, usually early in April, one will see just a few specks of yellow in among the fields of the English countryside, and likewise along the roadside verges and in the hedgerows, where the yellow has self seeded and now grows naturally. Step by step the yellow in the fields brightens and deepens and extends to fill within the spaces, till entire fields of unbroken golden yellow are splashed throughout the countryside – a show of brilliant depth.
This is oilseed rape, also referred to as rapeseed, or rape, a crop which has change into a significant function of the English panorama in the two months of April and should, and certainly is now a well-recognized sight in so many international locations across the globe. This web page is a pictorial evaluation of the crop, its history, its agricultural affect, and the contributions which it makes to the atmosphere of the countryside.
All pictures were taken by the creator in England. Among the panorama images were taken within the county of Cambridgeshire a number of years in the past. These have all been labelled thus. Nearly all of photos were taken within the county of Essex inside 5 miles of the creator’s residence during the rising of the rape crop in 2012.
DERIVATION OF THE Name
Rapeseed or oilseed rape is just one member of the Brassicaceae. This can be a family of plants which has offered mankind with a big and extremely essential range of crops, together with cabbage and cauliflower (Brassica oleracea) and types of mustard (Brassica – various species). The family additionally includes turnip, the Latin name of which is Brassica rapa, and it is from the species name of turnip – ‘rapa’ – that the very closely related species Brassica napus receives its curious frequent title of rape, a name which was first employed in the 14th century and was later utilized to all those plants from the household which were primarily grown for the extraction of vegetable oils (as opposed to these grown primarily for the consumption of roots or leaves .
History OF RAPESEED
The origins of rapeseed – B. napus – are unsure, partly because of the shut relationships and propensity for hybridisations between the different species of Brassica, but additionally because naming distinctions were not totally clear till comparatively recent occasions. The wild type of B. napus has not been found, and it is feasible that it is a pure hybrid between Brassica oleracea (cabbage) and B. rapa (turnip). Even in latest decades, selective breedings of new cultivars have involved hybridisations with several different species in addition to B. napus. But no matter the truth of its botanical history, geographically rapeseed would appear to be a plant initially from southern Europe .
Though some members of the household Brassicaceae were actually grown in Bronze Age instances and in historic Rome, plants which may be described as oilseed rape are believed to have been first cultivated in West Europe from in regards to the 13th century, while records from the 15th century are particular and many, and confer with the crop as a source of animal feeds, and of lamp oil for lighting . The time of the industrial revolution then tremendously expanded the uses to which rapeseed was put, and in the nineteenth century, the oil was developed as a lubricant for steam engines , Later on it was additionally used in the manufacture of products resembling soaps and plastics . World Conflict Two additionally gave a boost to the cultivation of rapeseed crops within the USA, specifically as a lubricating oil. This was as a result of the oil adheres effectively to metals beneath moist situations – a top quality which made rapeseed oil especially invaluable in naval applications [four].
This then was the state and range of the crop’s makes use of to mankind in the middle of the twentieth century.
THE LATE twentieth CENTURY – The event OF CANOLA
Up until the center of the 20th century as we have now seen, traditional uses of the plant had been predominantly within the fields of animal fodder manufacturing, fuel oil manufacturing, lubricating oil manufacturing, and a few other industrial applications. No mention has but been manufactured from its use in human consumption, and that could appear strange given that this is a crop in the household Brassicaceae – a famous meals crop family. Nonetheless, rape in its original kind suffered from a properly recognised downside. Two of the part components are erucic acid and glucosinolate. Erucic acid in high concentrations has been related to coronary heart disease, and extracted oil contained 50% acid by quantity. Glucosinolates give the oil a bitter taste, and break all the way down to launch mildly toxic byproducts inflicting digestive issues . Both traits made rapeseed merchandise poor candidates for human consumption (and indeed even for animal fodder, although it had been used for this function). Features of this downside were identified even back within the 16th century. Czech writer Cernobyl (1587) lamented that the ‘oil can also be superb, if somebody knows learn how to remove bitterness from it’ .
All this nonetheless was to change within the 1960s and 1970s, and the driving power for this variation was within the province of Manitoba in Canada. Selective hybridisation of B napus and the associated species B.juncea and B. campestris steadily decreased the erucic acid content and glucosinolate content to make new cultivars of the crop which have been more palatable. These new cultivars had been described as ‘double low’ or ‘double 00’ as each of those adverse elements have been decreased as low as potential. (Double low signifies that the processed oil contains less than 2% (USA) or 5% (Europe) erucic acid and the rapemeal less than three mg/g of glucosinolates) [four]. In 1979 the Western Canadian Oilseed Crushers Affiliation gave the brand new, more palatable strains the title by which they could also be known in North America. It was described as CANadian Oilseed Low Acid or ‘CANOLA’ . As we speak, the identify of ‘Canola’, as distinct from ‘rapeseed’, is particularly applied to all edible rape crops moderately than sorts grown to be used in industrial fuel or lubricant production [four]. Typically indeed, ‘Canola’ and conventional ‘rapeseed’ at the moment are recognized as two quite totally different crops.
Rape is a crop of temperate regions, and is not suited to the tropics or to high carbonization latitudes . A degree of frost tenderness has restricted eastward and northern unfold in Europe. However, reduction of toxic parts in Canola has not been the one aim of plant geneticists. They have additionally been aiming to make the crop more hardy, capable of germinating and growing at temperatures not much above 32ºF, 0ºC. This may allow the crop to be grown much more widely. Preferrred sowing conditions are well drained soils with sufficient water through the growing season, although the crop is kind of tolerant of various soils and totally different salinities [four].
Two different seasonal plantings have been developed, although each flower in the spring. ‘Winter’ crops can be sown within the early Autumn to make sure adequate development before probably severe weather circumstances set in, and must be ready for harvesting in mid-summer season, and these tend to supply a higher yield. The drawback after all, is that any frost tenderness limits the geographical vary of such plantings. ‘Spring’ crops can be sown as soon as possible after frosts, for harvesting late summer season, and that is the option in colder regions . After vegetative growth, flowering takes several weeks, after which seed pods mature over a interval of about 6 weeks [four].
Flowers are largely self-pollinated, and that is desirable particularly in the case of Canola cultivars. This is because although insect and wind pollination also contribute, these can lead to cross hybridisation between Canola and many closely associated species of cultivated and wild Brassicas, raising the erucic acid and glycosinaolate content material to unacceptable levels .

One key reason for the successful unfold of oilseed rape as a crop has been the sheer versatility of the plant. Since it was first grown in the Center Ages, the number of makes use of to which it can be put has expanded hugely. The next is an inventory of just among the industrial uses:
WINTER Cover: One in every of the benefits of winter rapeseed is the protection it provides to the soil, serving to to forestall nitrogen and different nutrients being leached out in the course of the very harshest months of the 12 months .
ANIMAL FODDER: Forty% of the seed yield is oil, and 23% is protein. The remainder of the seed is offered along with the leaves and stems as ‘rapemeal’, a excessive protein animal feed traditionally used for pigs and poultry, however now primarily reserved for cattle. In Europe this is a significant usage of the crop . The event of Canola greatly increased its worth on this regard.
HONEY: Maybe it’s a minor by-product, but honey could also be obtained from the nectar of rapeseed. The style is apparently robust, however combination with milder honeys makes it suitable for human use .
OIL FOR HUMAN CONSUMPTION: In fact the most obvious use to which a vegetable oil could also be put is in human consumption and in cooking, and since the introduction of Canola or double 00 varieties, this has been the most significant boost for oilseed rape cultivation. Canola seed oil just isn’t only palatable; it is usually healthier, as it is decrease in saturated fats and better in polyunsaturated fatty acids than the unique rapeseed, and it is subsequently frequently an ingredient in cooking oils and margarines .
Food FOR HUMAN CONSUMPTION: Although rapeseed is historically an oil producing crop reasonably than an edible leaf and root crop, within the Far East, Canola is used as a spinach-like stir-fried vegetable .
Fuel OIL IN Trendy Machinery: Rapeseed oil is used in trendy machinery, simply as it was utilized in 19th century steam engines. The advantages are many, and although more expensive than mineral oils, it’s claimed to be more environmentally pleasant and less hazardous . In several nations, equivalent to Austria, some mineral fuels – for instance petroleum primarily based chainsaw oil – have been banned because of environmental considerations, thus growing the worth of vegetable oil fuels . The previous decade has even seen the introduction of a new time period for such oils – biodiesel, a sustainable, growing supply of fuel for diesel engines and lots of different industrial purposes. Rape is under no circumstances the only supply of biodiesel, because the gas will also be obtained from soybean oil, algae, and animal fats comparable to lard and fish oil, Certainly, soybean is by far crucial supply in the USA, however the value of rape on this regard is rising, and about two thirds of European rapeseed oil production now goes into biodiesel fuels .
World Expansion OF Manufacturing
As will probably have been appreciated at this stage in the article, rapeseed and Canola – if one chooses to differentiate between the two – are two crops which have undergone immense expansion of cultivation within the final 50 years. The proliferation of uses to which rapeseed / Canola have been put has increased the market value and led to much more land being given over to the crop .
World vast production in the 1950s amounted to a mere 3.5 million metric tons (three.5 million kilograms). By 1975 this had greater than doubled to eight.5 million metric tons, and by 1985, it had doubled again. In 2006, world production had expanded to 47 million metric tons, and it continues to be rising . Oilseed rape is now the world’s third largest source of vegetable oil after soybean and oil palm . It’s also the second leading supply of protein meal after soya .
This growth in manufacturing has come from two key developments and one ecological consideration, all of which have been alluded to above, and are here summarised:
PALATABILITY OF CANOLA: The first growth was the hybridisation and selective breeding of Canola, which has enabled a vegetable oil to grow to be palatable and subsequently harnessed for extra than just lubrication and fuel. Canola has seen a large rise within the commercial cultivation of rape for human and animal consumption. In Europe since 1991, virtually all rapeseed has been ‘double low’ [three].
HARDINESS AND RESISTENCE TO Illness: Along side the event of palatable Canola strains came development of hardier, more frost-resistant varieties, as well as the event of disease resistant strains, and these components have enabled the enlargement of the crop not merely in terms of its gross production figures, but also in terms of its increased geographical distribution to the colder areas of Europe and Canada.
ECOLOGICAL Issues: The rise in ecological considerations over sustainability of sources has additionally increased demand for the crop. Depletion of fossil fuels such as petroleum, pure gas and coal, have just lately led to the development of biodiesel – vegetable oil (or animal fats-based mostly) gas for use in diesel engines, or as a low carbon alternative to heating oil. In the UK, gas suppliers at the moment are obliged to make sure a minimum of 5% of all fuel is from renewable sources – ie, from biodiesel. Equally use of biodiesel is rising in the USA for the reason that Energy Coverage Act of 2005.
Since World Struggle Two within the newly formed European Neighborhood, generous subsidies have encouraged farmers to develop the crop. 16 million metric tons are actually cultivated annually, with Germany and France the leading producers. In Nice Britain, oilseed rape is now the third most essential crop after barley and wheat . In Western Europe, winter grown rapeseed is most common , In Eastern Europe, production has been hampered by the severe winters, however spring grown rapeseed, together with other spring Brassicas and the introduction of chosen hardier varieties as indicated above, is growing the geographical range .
India and China also turned major growers put up-war, and India now has 10-15% of its farmland under rapeseed cultivation, producing 6 million tons annually [three]. China as an individual nation is now the world’s largest producer of oilseed rape in all its forms, answerable for more than 12 million metric tons in 2006.
The position of Canada in the event of Canola led to its pre-eminence within the cultivation of double 00 varieties with 9 million metric tons harvested annually, and right this moment this – with wheat – is the main crop in that country . The purpose is to increase the full production determine to 14 million tons by 2015 . The seed and seedlings of the rape crop are naturally liable to many soil pathogens, and undoubtedly, one of the coverage choices which enabled Canada to assume this pre-eminent place was the authorisation to use seed safety fungicides, which weren’t sanctioned or registered in all different international locations. Genetic modification has performed a considerably higher position in Canada than in Europe, the place most crops are free of modification . In Canada’s primary rape rising provinces, 82% crude oil price chart august 2015 of the crop is genetically modified spring rape .
Within the USA, rapeseed remains to be a much less important crop however is now grown extensively significantly in the corn belt and in the southeastern states. Minnesota and North Dakota are the 2 biggest producers .
A SPLASH OF Beauty OR A GARISH SCAR – Results ON THE Panorama AND Other CONTROVERSIES
Any monoculture crop will inevitably provoke controversy in the modern, very ecologically minded period, and especially so when it’s a crop which has undergone many hybridisations and genetic modification, notably in Canada. (Nearly all of European manufacturing is GM free) . For each proponent of this crop as a provider of more and more healthy vegetable oil and a sustainable natural supply of gas, there will likely be a detractor who can level to considerations over in depth genetic manipulation, and environmental downsides which embody the usage of nitrogen fertilisers in the cultivation of Canola leading to the discharge of the greenhouse gasoline nitrogen dioxide . Some additionally suggest that ecological benefits of biodiesel gas are not as impressive as they could seem at first look. This article is just not supposed to open up the debate, but involved parties can learn the articles listed within the references later, and different hyperlinks from these.
Along with the environmental and well being issues, the crop even have its aesthetic detractors. Although within the caption to one of many images on this page, I described oilseed rape as ‘affording an attractive vista for those who’ve their houses close by’, some claim that these plants trigger allergies and hay fever like symptoms, asthma assaults and conjunctivitis in some members of the inhabitants . It also has a pungent odour when the wind carries the scent, and it remains a matter of opinion whether or not the fields of gold are fields of beauty or fields of unnatural garishness.
Canola or double low rapeseed (as opposed to conventional rapeseed) is considered safe for human consumption in all nations, and advocates claim it is useful in the discount of cholesterol ranges. Further research is being undertaken to introduce extremely low saturated fats and Omega3 enhanced Canola for the well being acutely aware age we reside in . Extra environment friendly strategies of oil extraction from the seeds are additionally under research with new applied sciences to cut back the worth, and many new products which harness vegetable oils like this are being developed . Whatever controversies exist, it does seem that this yellow crop is here to remain. I would direct readers to the pages listed under, and to further hyperlinks from these sites for extra detailed data on all points of the event and cultivation of rape crops. My principal cause for penning this web page was simply to file and illustrate with images the explanations behind the extraordinary change which now occurs each twelve months in the fields of England, and more and more in so many different international locations of the world, as brown gives option to inexperienced and then to vibrant good yellow.
For good or bad, oilseed rape has certainly made its bold and extravagent mark on our countryside.

jonnycomelately; Very happy to hold the link. As you possibly can in all probability inform, I have no strong views on the controversy in regards to the cullinary benefits of Canola. (How can I, when my weight loss program tends to consist of quick foods, and anything that may be cooked in a microwave or one frying pan! ) My own private greater interest is within the environmental impact, and the aesthetic enchantment (as an newbie photographer and lover of the countryside).
Nonetheless this crop is clearly one which is having an rising impact in all kinds of the way, so no doubt the debate on the benefits or in any other case of this and related crops will proceed.
Many thanks in your go to and very good feedback. Alun.
Alan 5 years ago from Tasmania
Alun, thanks for this Hub. You’ve got written it extraordinarily effectively…. it is readable, comprehensive in its treatment of the subject and you have approached every aspect impartially.
I’ve been interested in this topic for a number of years now, ever since reading articles by Sally Fallon and Mary G. Enig, http://www.whale.to/a/fallon_h.html
I have been fortunately tucking into butter, entire eggs (out of their shell in fact !) and animal fats. It seems there was a number of misinformation concerning unsaturated fats, primarily from “scientists” employed by firms manufacturing vegetable oils.
I will not take sides here, simply put up the link for your self and any others to follow if interested.
Please sustain the good work, Alun.

Thank you a lot for visiting and commenting. I actually admire your visits. I am previous enough to recollect the days earlier than a few of the fields in England turned bright yellow. You may be able to guess from my feedback in the article, I can not fairly make up my own thoughts whether I just like the rapeseed crop from an aesthetic standpoint. It seems both unnatural and but really beautifully colourful compared to the standard hues of the countryside.
In recent years I’ve not done much photography apart from when I’ve been on trip in places like Thailand or Jordan, however it was really pleasurable to enterprise out with a digital camera a number of weeks in the past to spend just a few hours within the fields near my residence taking pictures for this article.
Thanking you once more.

Alun, What a compelling, fascinating, intelligent presentation of the life and times of rapeseed and canola oil! Particularly, I recognize the data on Canadian Oil Low Acid’s invention and purposes. It is a succinct, useful history which you share, in a single handy location and with footnotes.
Also, it is useful to find in one place all of the wants which may be met by the numerous kinds that one crop takes. It’s interesting that it will probably “feed” animals, machinery and other people. However then in a approach the use that basically will get my attention is floor cover, which will be so vital in sustaining, protecting and restoring soil health and the soil meals web.
Up + UFABI.
Respectfully, and with many thanks for sharing the information and your gorgeous original pictures, Derdriu
P.S. As a lot as I admire spring and summer yellows — including the yellow, crimson-yellow and green-yellow glows of fireflies — I also actually like the blues of bluebells, chicory, flax, hyacinth, and violets each spring to summer.
