8. Cereals
How are cereals farmed?
Cereals or grains, such as wheat and barley, are farmed in fields. The soil type of these fields is easy to work with and high in nutrients. It is sometimes necessary to prepare and plough the soil before it can be used for cultivating cereals.
The stages of cereal farming:
- planting (the seeds and fertilizers are placed in the soil). Fertilizers contain nutrients important for plant growth, such as nitrogen, phosphorous and potassium.
- taking care of plant growth (e.g., preventing the spread of weeds and harmful insects)
- harvest (the seeds of the plants are collected with a combine harvester).
After the harvest, the seeds are dried. When the seeds are dry, they are ready to be milled. When this happens, the seeds are ground into flour and animal feed.

Oat
Oat is a common cultivated plant, especially in areas where wheat does not grow well. Oat can survive in cold and rainy conditions. Oat is used to create flour and flakes. The best-known oat-based food is probably porridge. Oat flour can also be used to bake bread, whereas oat flakes are found in muesli and many biscuits. Nowadays, oat is also used making non-milk dairy products.
Oat is considered a healthy cereal. It contains a lot of important nutrients.
Celiacs, who cannot eat gluten, can eat pure oat products. Oat does not contain gluten.

Barley
Barley is one of the oldest cultivated plants in the world. Even in Northern Europe, it has already been farmed for over 3 000 years.Barley plants can be identified by their long, prickly awns.
Barley is mostly used to make feed for livestock and farm animals. It is also used to make beer, bread and porridge.
Barley is not a very useful baking cereal.
However, it contains a lot of important fibres, which is why it is good for the stomach.
Rye
Rye is a cereal that can grow even in low-quality soil. It is capable of surviving harsh climate conditions, which is why it is one of the most important cereals in Finland. Rye can be farmed twice a year, both in the spring and in the autumn.
Spring rye is planted during the spring, whereas autumn rye is planted during the late summer, as soon as the spring rye has been harvested.
Although a lot of rye is produced in Finland, it is not enough to satisfy the nation's rye consumption. This is why it is also imported from countries like Germany and Poland.
Rye can be made into flour, which is used when making dark rye bread. Rye can also be used to make porridge.
Wheat
Wheat is one of the world's most widely cultivated plants, together with maize and rice. Wheat is a very old cereal species, although it arrived in Finland only during the 20th century.
Wheat requires a long and warm growing season. Like rye, it can be planted both during the spring and during the autumn.
The health effects of wheat depend on which parts of the cereal's grain are used. If the outer parts of the grain are removed (to create white flour), many important nutrients are also lost. Whole-grain wheat is healthier than purified, white wheat flour.
Wheat is used to produce many kinds of products, such as flours, bran, flakes and couscous. Wheat is the most common cereal in white bread, as it produces a fluffy texture to the bread. Many types of pasta (such as macaroni and spaghetti) are also made from wheat.
Celiacs cannot eat wheat because it contains gluten.
Millet and buckwheat
Millet and buckwheat are used to replace other cereals when making glutein-free products. These products are mainly targeted for celiacs, who cannot eat glutein. In addition, buckwheat contains a significant amount of important proteins.
