How to identify farm crops on a country walk

a guide to farm crops

A post to help you identify 25 of the most common farm crops you might see as you go hiking through the countryside.

While hiking through the countryside, do you sometimes wonder what the crops are that are growing in the fields around you? Would you like to know how to tell barley from wheat? Or rye from oats? Or know what a field of sugar beet or soybeans looks like?

If so, you have come to the right place. This post covers 25 crops, grouped into three main categories: cereal crops, forage crops, and industrial crops. Each has short descriptions to enable you to identify the crop, whether by flower, seed, fruit, root …

At first I was focusing on crops in Belgium, which is where I live, although of course many of these crops are also grown in other areas of western Europe and indeed other parts of the world. But so popular has this post become that I have extended it to crops grown elsewhere in the world.

Moreover, as Henry points out in his comment below, “being able to understand the farm-to-table chain of events is vital for both a healthy planet and a nutritious diet.” In this respect, this post would be useful for children too. It would certainly make a “boring” walk in the countryside more enjoyable, entertaining and educational.

CEREAL CROPS

Cereals, or grains, are members of the grass family (Poaceae). They are cultivated primarily for their starchy dry fruits. Wheat, rice, corn (maize), rye, oats, barley, rice, sorghum and millet are the most common cereal crops. Cereal crops can be used for human food and livestock feed, but they have other uses such as industrial starch and biofuel. The first cereal to be cultivated by humans is believed to be wheat, around 8000 BC. Rice is thought to have been cultivated later, perhaps not until about 2500 BC.

WHEAT

Wheat can be identified from similar crops by its short “beard” (the bristly material protecting the kernels). When ready for harvesting, it has a golden-brown color. Wheat is milled and turned into flour, ground into semolina, or broken or pre-boiled to turn it into bulgur. It drives the bread and pastry industries and is used for a huge variety of foods.

Wheat ready for harvesting

There are six main types of wheat: hard red winter, hard red spring, soft red winter, hard white, soft white, and durum. Within these types, there are thousands of wheat varieties. The most important are common wheat (Triticum aestivum), durum wheat (T. durum), and club wheat (T. compactum).

Wheat at a younger stage

The global trade of wheat is greater than all other crops combined. China, India and Russia are the three largest wheat producers.

BARLEY

Barley is an important grain for the production of alcoholic beverages such as beer and whisky. However, 70% of global barley production is used as animal feed.

Barley

There are three types of barley: two-row, six-row and hull-less barley. It can be identified by its longer “beard” than wheat and when ready to harvest is yellow-white in color. Barley can also be identified by the fact that the whole spike bends; the spikes of wheat and rye tend to stay much straighter. Two-row barley tends to have a “flatter”, two-dimensional appearance.

A field of ripe barley creates a “fuzzy” appearance thanks to the longer “beard”.

RYE

Rye is closely related to barley, and distinguishing the two is difficult. Rye tends to be longer and more slender than barley or wheat, and is characterized by a longer beard. Identification is further complicated by the fact that there are barley x rye hybrids.

Rye

Rye is extensively used in flour, bread, beer, crispbread, some whiskeys, some vodkas, and animal fodder.

The longer “beard” of rye is its best identifying feature

Rye grows well in much poorer soils than those necessary for most cereal grains. Rye plants also withstand cold better than other grains do.

WHEAT, BARLEY OR RYE?

Another difference between these three cereals is the number of seeds. Barley seeds are solitary; rye seeds come in pairs; wheat seeds come in triplets. This is nicely illustrated below.

OATS

After the challenge of working out the differences between wheat, barley and rye, oats are easier to identify. Oats don’t grow in spikes like wheat, barley and rye, but in what are called panicles.

how to identify farm crops: oats
The typical panicles of oats

Oats are a hardy cereal that can withstand poor soil conditions in which other crops are unable to thrive. Their high nutritional value makes them popular for breakfast cereals, muesli and cereal bars.

The grains of the first three cereals – wheat, barley and rye – contain the protein gluten, which triggers the autoimmune response seen in people with celiac disease. They therefore cannot be part of a gluten-free diet. Oats on the other hand do not contain gluten.

THE FOUR TOGETHER

Here is a neat comparison of all of the first four common cereals described so far.

MAIZE

Maize (also known as corn) was first cultivated by indigenous peoples in southern Mexico about 10,000 years ago.

maize crops in Belgium
This is a very common sight in Belgium!

The male and female inflorescences (flower-bearing parts of the plant) are positioned separately on the plant. The male inflorescence is known as the ‘tassel’ or ‘silk’ while the female inflorescence is the ‘ear’. The ear of the maize is a modified spike and there may be 1-3 per plant. The maize grains, or ‘kernels’, are encased in husks and total 30-1000 per ear.

Ready to pick in a few weeks?

Maize is a staple food in many parts of the world. It’s consumed directly by humans and also used for corn ethanol, animal feed, corn starch, bourbon whiskey, and corn syrup.

RICE

There are only two species of cultivated rice in the world, Oryza sativa (Asian rice) and Oryza glaberrima (African rice). Rice plants produce three flowers on a spikelet. The rice grain is formed by the ripened ovary of the flower and is between 5 and 12 mm in length.

Rice

Rice is an annual plant, harvested after one growing season. It can reach a height of between 1 and 1.8 meters. Generally, African rice tends to form smaller grains and is more difficult to mill. Asian rice is now replacing African rice in West Africa.

Typical rice field or rice paddy

Roughly one-half of the world population, including virtually all of East and Southeast Asia, is wholly dependent upon rice as a staple food. 95 percent of the world’s rice crop is eaten by humans.

SORGHUM

The tiny flowers of sorghum are produced in panicles; each flower cluster bears 800 to 3,000 kernels. The seeds vary widely in shape, size and color, and are smaller than those of wheat.

Sorghum

Sorghum probably originated in Africa, where it is a major food crop. Sorghum’s global importance is largely due to its natural drought tolerance and versatility. In Africa and parts of Asia, sorghum is primarily grown for human consumption. The world’s largest producer is USA, where it is mainly used for livestock feed and ethanol production. Interest in growing sorghum is accelerating, partly because it’s naturally gluten-free.

MILLET

Millet is a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. They are especially important crops in Africa and Asia. Here they are mainly consumed in flatbreads and porridges or prepared and eaten like rice.

pearl millet
Pearl millet

The most widely grown millet is pearl millet, but other important types are finger millet, proso millet and foxtail millet. Pearl millet is identified by its inflorescence which is a spike-like panicle, made up of many smaller spikelets where the grain is produced.

CANARY GRASS

Originally from the Mediterranean region, canary grass is commercially grown in various areas of the world for birdseed, hence its name.

Canary grass

You might be seeing more of this crop in years to come. It is regarded as a promising cereal for human consumption due to its nutrients and health benefits. It apparently reduces cholesterol, blood pressure and inflammation, and maintains glucose levels.

Canary grass is fairly easy to distinguish from other crops as it’s shorter and fatter.

FORAGE CROPS

Forage crops are crops grown specifically to be grazed by livestock or conserved as hay or silage. When harvested as whole plants and cured for animal feed, they are called fodder. Forage crops thus contribute to the supply of nutrient-dense foods like meat and milk as well as products like leather and wool. Some cereal crops already mentioned are also used as fodder in certain parts of the world. These are notably maize, rye and sorghum.

CLOVER

Several species of clover are extensively cultivated as fodder plants. The most widely cultivated clovers are white and red clover.

clover
Red and white clover

Clover gives a lot of benefits. It produces an abundant crop; it is palatable to and nutritious for livestock; it fixes nitrogen, reducing the need for synthetic fertilizers; it grows in a range of soils and climates; and it’s a valuable source of nectar for honeybees.

4 leaved clover
Approximately 1 in 5000 clovers have four leaves.

Clover leaves are easily identified by their three oval-shaped leaflets. Maybe you’ll find a lucky four-leaved clover? This is due to a rare genetic variation.

LUCERNE

Known as alfalfa in North America, lucerne is a close relative to the clovers. It has clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10-20 seeds.

how to identify farm crops: lucerne
Lucerne

Its primary use is as feed for high-producing dairy cows, because of its high protein content and highly digestible fiber. Other uses include feed for beef cattle, horses, sheep and goats. Humans also eat alfalfa sprouts in salads and sandwiches. Indeed, it’s being increasingly grown in gardens as a herb and a source of calcium, potassium, phosphorous, iron, and vitamins A, C, E, and K.

FODDER BEET

Fodder beet is also known as mangelwurzel, mangold wurzel or field beet. It’s a cultivated root vegetable variety of Beta vulgaris, which also contains beetroot and sugar beet varieties. It’s identified by large white, yellow or orange-yellow swollen roots, below dark-green, heart-shaped leaves.

Fodder beet

Fodder beet is an easily digestible, energy-rich food for cattle during the winter. It can also be given to pigs. Both leaves and roots may be eaten by humans. This has especially been the case over the years during famines, such as the Irish Famine in the 1840s.

SWEDES

Swedes are one of the highest energy forage crops. Compared to other similar forage crops such as fodder beet, swedes produce a far greater amount of metabolizable energy.

swedes
Swedes

Swedes are used to provide food for livestock, particularly sheep. The feed value of swede is so high that one hectare is capable of sustaining a flock of 80+ sheep for up to 100 days. The plant is usually a pale green, with waxy leaves. The root is purple, with yellow flesh.

INDUSTRIAL CROPS

Industrial crops are crops that are normally not sold directly for consumption but are industrially processed prior to final use. They can be starch-bearing crops; sugar-bearing plants; oil crops; or textile crops. Or they could be crops that yield rubber, tannins (tea, coffee), dyes, medicinal substances or narcotics. Some industrial crops have double uses, such as flax, hemp and cotton which yield both fiber and oil. Following are 12 of the most widely grown industrial crops around the world.

FLAX

Flax, also known as linseed, is a flowering plant that is cultivated as a food crop and for its fiber. Textiles made from flax are used for bed sheets and table linen. Its oil is known as linseed oil. Apparently, the best flax in the world is grown in Belgium, Northern France and the Netherlands. The combination of suitable soil with alternating rain and sunshine makes the region ideal for flax. Coming across a field of blue flax on a country walk is a special sight.

Flax is one of the most sustainable fibers in the world. All parts of the plant can be used, so there is no waste, and untreated (not dyed) flax textiles are biodegradable.

SUGAR BEET

Sugar beet juice contains high levels of sucrose and is second only to sugar cane as the major source of the world’s sugar.

Sugar beet

Sugar beet was grown as a garden vegetable and for fodder before being used as an industrial crop. Sugar beet production only took off after 1811 when a British blockade cut off France’s raw sugar cane supply from the West Indies. Beet sugar now accounts for almost all sugar production in the European Union and for about one-fifth of total world production.

OILSEED RAPE

The bright yellow flowers of oilseed rape are familiar sights across many areas of the world. It’s grown for the purpose of extracting oil from the seeds. The oil is then used in margarine, mayonnaise and similar products. It’s probably the easiest crop to identify while on a country walk.

oilseed rape how to identify farm crops
Oilseed rape is one of the most colourful farm crops!

 Originally it was grown as a “break crop” in farm rotation to suppress weeds and improve soil quality in readiness for cereal crops. But in the last 20-30 years it has become hugely profitable. This is because rapeseed oil is one of the highest quality vegetable oils. It has a good health profile; low in saturated fat and high in omega-3. It also gives high yields: 45% of its tiny black seeds are oil, and the other 55% is high protein animal feed.

SOYBEAN

The soybean has been used in China, Japan and Korea for thousands of years as a food and a component of medicines. Soybeans were introduced into the USA in 1804 and became important in the South/Midwest in the mid-20th century. Brazil and Argentina are also major producers.

Soybeans have a multitude of uses

The soybean is economically the most important bean in the world, providing vegetable protein for millions of people. Popular soy foods include soy milk, from which tofu is made, soy sauce and tempeh. De-fatted soybean meal is an important source of protein for animal feeds and an ingredient in meat and dairy substitutes.

Soybeans form inconspicuous white or pink flowers.

Soybean fruit

The fruit is a hairy pod that grows in clusters of about 3-8 cm in length. Each usually contains two to four beans.

POTATO

Famously brought to Europe from the Americas by the Spanish in the second half of the 16th century, the potato is a staple food in many parts of the world and an integral part of much of the world’s food supply.

potato flowers
The flower of the potato

About one third of the world’s potatoes are grown in China and India. China is the number one potato producer in the world. Each year around 360 million metric tons of potatoes are produced worldwide.

COFFEE

What we call coffee beans are actually the seeds inside the coffee plant’s berries or “cherries”. These appear after the white flowers.

Doesn’t look like what we think of coffee!

The coffee plant is native to subtropical regions of Africa and Asia, but is now cultivated throughout Central and South America too. Once the berries are harvested, the flesh is removed and the seeds roasted.

This is more like it!

As coffee is one of the world’s most widely consumed beverages, coffee beans are a major cash crop and an important export product, accounting for over 50% of some developing nations’ earnings. Almost half of the world’s coffee is produced in South America, and in particular Brazil. The two most economically important varieties of coffee plant are the Arabica and the Robusta.

TEA

The tea plant is an evergreen shrub native to a number of Asian countries. After water, tea is the most widely consumed drink in the world.

Tea leaves ready for picking

The flowers are yellow-white, and the seeds can be pressed to yield tea oil. But it’s the leaves that are the most important part of the plant. Young, fresh leaves contain about 4% caffeine. Usually, the tip (bud) and the first two to three leaves are hand-picked from tea plants every one to two weeks.

Typical tea plantation in Sri Lanka

China is the world’s top tea producer, with 40% of the world’s tea, weighing in at 2.4 million tonnes. It’s followed by India, Kenya and Sri Lanka.

COTTON

Cotton is a soft, fluffy fiber that grows in a “boll” around the seeds of the cotton plant. The fiber is almost pure cellulose. The cotton plant is native to tropical and subtropical regions around the world.

Cotton bolls

The fiber is spun into yarn or thread and used to make textiles. Cotton fabrics dating back to 6000 BC have been found in Peru. Cotton makes up about 2.5% of the world’s arable land. India produces the most cotton in the world, followed by China and the US.

RUBBER

Rubber is harvested in the form of a sticky, whitish, milky fluid that is produced in the cells of the rubber tree. It is drawn off by making incisions in the bark and collecting the fluid in vessels.

Rubber seeping from a rubber tree on a plantation

Rubber displays high strength and the capability to be stretched many times without breaking. Natural rubber compounds are very flexible, waterproof, good electrical insulators, and resistant to many corrosive substances.

Thailand is the leading natural rubber producer in the world, followed by Indonesia. Industrial demand for rubber began to outstrip natural rubber supplies by the end of the 19th century, leading to the synthesis of synthetic rubber in 1909 by chemical means.

HOPS

Hops are the flowers of the hop plant Humulus lupulus; a vigorous, climbing plant that is usually trained to grow up strings in a field. Inside each flower are tiny yellow pods called lupulin – the source of bitterness, aroma and flavor in beer.

Hops

Hops have separate female and male plants, and only female plants are used for commercial production.

Hop farm

Two-thirds of the world’s hops are grown in the European Union, notably Germany, Czech Republic, Poland and Slovenia.

TOBACCO

Over 70 species of tobacco plant are known, but the chief commercial crop is Nicotiana tabacum. After the leaves are harvested, they are hung in a curing barn. Curing prepares the leaves for consumption because, in their raw, freshly picked state, green tobacco leaves are too wet to ignite and be smoked.

Tobacco leaves ripe for the picking

Interestingly, despite the health hazards of smoking, global production of tobacco hasn’t changed over the last few decades.

Tobacco leaves hanging in a curing barn

What has changed is location of production. It has shifted from high-income countries in Europe and North America to low- and middle-income countries in Africa, Asia and South America. Brazil, China and India are now the dominant tobacco leaf producers.

INDUSTRIAL HEMP

Hemp is not the same as marijuana; they are varieties of the same plant (Cannabis sativa). The difference is the concentration of tetrahydrocannabinol (THC), the active substance in “drug-type” marijuana. Industrial hemp has less than 0.2% THC; recreational marijuana has up to 20%.

hemp
The familiar hemp leaf

Hemp is extremely useful; its stalk, seeds, flowers and leaves can all be harvested and processed into products that are reusable, biodegradable and compostable.

hemp field
Industrial hemp plantation

Hemp and cannabis plants look very similar and both share the same leaf shape. Hemp plants however, are skinnier and taller, growing up to 6 meters high. Hemp leaves tend to be concentrated at the top of the plant, so leaving the lower stem with few or no leaves. Marijuana plants are smaller, fatter and bushier.

  1. Thanks for this, Denzil. It’s really useful because I feel very ignorant when I’m walking through the fields and I love seeing the new crops grow.

      1. Loved this informative article. Also, love tooling around my old farming community & discovering just what crops are,? teehee,? coming up, here in the mid Willamette Valley of Oregon.
        Spent plenty of my childhood jumping outta the rafters of a magnificent mortise & tenon, 1900 built barn. Jumping from way up top, into the ground floors deep bins of barley! It was the best of the grains to jump in, because it isn’t pointy! Not just raised a farmers daughter, but flew of the trapeze!? BORN1956?

        1. Thanks for joining the conversation Susun all the way from deepest Oregon! Your childhood sounds fun, growing up on a farm. Jumping into deep barley sounds invigorating. Perhaps not in your 60s though!

    1. Just returned from a country walk here in North Scotland, and tried to identify what I was seeing growing in the fields. The 4 types of ‘ears’ put together solved my problem! I saw rye this time.
      Thank you
      Vicki

  2. This is great, Denzil! Sometimes a body meet a body comin’ thro’ the rye, and then realize, no, they’re barrelin’ thro’ the barley, or walkin’ thro’ the wheat. Seriously, sometimes I’ve seen a field and decided it wasn’t the usual winter wheat, that’s grown around here, and I know the numerous microbreweries have encouraged farmers to plant some barley again, but I wasn’t sure if that’s what I was seeing. And the same people are bringing back hops as a crop, that’s kind of an unusual-looking field, with the poles and cables.
    Oats are my favorite – – beautiful silver-green in the spring, and beautiful tawny color in the fall.

    1. Hops! That’s a good one to add as they are grown in Belgium. And grapes too. So there’s two more to add. Maybe I should add a section on ingredients for beverages. Yes I like oats too, and I’m not talking about the UK slang meaning.

  3. Hi Denzil,

    This is a wonderfully educational post since so many urbanites have been become disconnected from their food supply. Being able to understand the farm to table chain of events is vital for both a healthy planet and nutritious diet. Thanks for sharing the text and photos!

    1. You make a valid point Henry and one that I am going to steal to add into the text! I was focusing purely on identification, but there is a great educational message here too, also for children. Thanks!

    1. For some reason I always thought that a mangelwurzel was a scarecrow. Yes these old words need to be retained, used and not forgotten!

      1. Hi Denzil,

        Thank you for your well-written and informative post. I used it to check that I had remembered the grains correctly from school and I really enjoyed the other crops you mentioned.

        I don’t usually read comments – but it struck me that as field beets or manglewurzles are often used as the head of a scarecrow that may be where the author Barbara Euphan Todd got the idea for the name Wurzle Gummidge and the link to scarecrows in your mind. Wurzle Gummidge has been around for about 100yr and number of UK TV series have kept him and his friends in the public consciousness.

        PS I also love the Mandela-like icons that come up against people’s names.

  4. So interesting, Denzil. I lived in the Canadian province of Saskatchewan in the 1980s. All those grains are grown there, as well as flax and rape (although it’s called “canola” here). Not being involved in farming, I never realized the differences between the different grains. And a field of flax in bloom is a wonderful sight!

    1. I prefer the name canola, for sure! A field of flax also looks attractive after harvest time, when the cut flax is laid out on the fields in neat rows.

  5. Denzil, I have to admit that when I read the title of this post, I made a bit of a groan. But what an absolutely fabulous article this is! I loved reading every part and comparing all the various grains, especially seeing the grains close up. I had no idea white asparagus is so labor intensive. I’m fascinated by the factory where each stem is sorted and packaged by some many different machines and so many people. This post makes me even more grateful for the work by farmers and crop laborers all over the world who make my table a bounty of health and goodness to eat. Thank you, all of you.

    California is better known for other crops than these, and we have to drive a long distance to see them. The central swath of our state is well known for its agriculture, and when we drive it, we enjoy seeing orchards, vineyards, and all sorts of crops.

    1. Glad you liked it Sharon. I’ll be adding some pictures of vine and hops. But I know for a certain that our little Belgian vineyards will seem like mini-pockets compared to the Californian vineyards! Yes I was hooked on that asparagus video; fascinating!

  6. Brilliant, this is so useful . . always get confused with Barley and Rye, maybe I won’t now though!

    Your asparagus looks very different to ours

    1. Thanks Becky. Yes I wasn’t aware that there are different types of asparagus. I prefer to see the frilly above-ground asparagus waving in the breeze!

  7. Thanks. I ride my bike on trails just outside the city and was wondering what grain I saw. My grandparents were farmers in Alberta Canada and frankly I never paid attention. I love the canola fields the most. I identified it was wheat I saw which is what I thought.

  8. Very informative. Although I live in Canada. It will be interesting to see if there are any differences between the crops in Canada and Belgium. Thank you!

    1. Thanks for your comment Martin. Surprisingly, this post is getting a lot of attention all over the world. Maybe I need to expand it to include other crops?

  9. Wonderful guide Denzel. Thanks. It has helped me identify the crops in the field I am walking my dogs round at this moment.

    Love your passion for the subject. Keep up the great work.

  10. We also grow other bean crops. White, colored, black … But, I am sure you , like us, grow various “market” vegetables. Maybe a section on these? Celery, peas, spinach, lettuce, broccoli etc. And, hey, mustard is a crop too.

  11. Lived on a Mennonite farm in Germany where I learned to tell the difference (though I knew wheat from the US) and appreciate the review. White spargl is the best! Maybe add commercial hemp to the list?

  12. Hi Denzil, thanks for starting this! Like other townies I don’t know what our precious food crops look like. I saw a few stalks of things growing randomly in a small park in the UK and wanted to ID it. Humans have grown so far away from our connection with vegetation—maybe with King Charles III’s new reign and love for healthy growing, there might be a renewal of interest in it (with 65 million people to feed, we could do with a few more growers!) ??
