Welcome to our blog on “Growing Green: The Secrets Behind Successful Greenhouse Farming Techniques in Sweden.” This article delves into the fascinating world of greenhouse farming in Sweden and explores the key techniques contributing to its success.

Greenhouse Farming in Sweden

With a combination of innovative practices and a commitment to sustainability, Sweden’s greenhouse farmers have created an efficient and eco-friendly agricultural system. These practices have yielded impressive results from advanced climate control systems that optimize growing conditions to carefully selecting crops for maximum yield.

Sweden Greenhouse Growers and Agriculture

In 2017, Sweden had 1,952 professional horticultural holdings, with over 14,800 employees engaged in this industry. Of these, 1,555 holdings practiced open-ground cultivation on a vast expanse of 12,807 hectares. Meanwhile, 744 holdings focused on greenhouse cultivation, utilizing just over 286 hectares of land. Looking at the open ground area, approximately 59% was dedicated to vegetable cultivation, while berry, fruit, and ornamental plant cultivation occupied 24%, 13%, and 4%, respectively.

As for the greenhouse area, it was fairly evenly divided between ornamental plants and vegetables or berries. The major crops in terms of area in 2017 were strawberries, carrots, apples, onions, and iceberg lettuce, listed in descending order. Deciduous trees took the lead for ornamental plants, occupying just over 48% of the available open ground area. Some crops showed significant changes in production compared to previous years.

Cauliflower, broccoli, onions, and pumpkins had unusually high harvests, while spinach and dill production decreased by 93% and 52%, respectively, mainly due to reduced demand from the food industry. Apples also experienced a notable decline in yield due to a frosty spring, but an increase in cultivated apple area mitigated the overall decrease. Swedish greenhouse production has been focusing on energy efficiency and renewable fuels.

However, in 2017, the progress in energy efficiency halted, resulting in a 4% increase in relative energy use to 210 kWh per square meter compared to 2014. Nonetheless, there was a positive trend in transitioning towards renewable fuels, with the share of energy from renewable sources increasing from 48% to 57% during the same period. Agriculture in Sweden varies across regions due to differences in soil and climate.

The northern and mountainous parts of the country are more suitable for forestry than agriculture due to shorter growing seasons. However, the southern tip of Sweden is the most agriculturally productive, benefiting from the longest growing season, exceeding 240 days in some areas. Southern Sweden cultivates crops like wheat, rapeseed, and sugar beet. At the same time, barley and oats are more common in the northern regions, primarily for animal feed, particularly for pigs and poultry.

Types of Greenhouses in Sweden 

Sweden boasts various greenhouse shapes, each designed to suit specific needs. The most common shapes include the classic even-span, the economical quonset, the versatile gothic arch, and the spacious gutter-connected greenhouse. These structures are designed to endure harsh weather conditions while ensuring optimal sunlight exposure for crop growth.

  • Polyethylene Greenhouses: Polyethylene greenhouses are cost-effective and widely used in Sweden. They are easy to assemble and offer adequate insulation, maintaining favorable crop temperatures.
  • Glass Greenhouses: Glass greenhouses are favored for their durability and aesthetic appeal. They provide excellent light transmission, creating an ideal environment for delicate crops.
  • High-Tunnel Greenhouses: High-tunnel greenhouses are temporary structures that extend growing seasons for seasonal crops, offering protection against frost and pests.
  • Shade Houses: Shade houses regulate excessive sunlight exposure, especially during hot summers, safeguarding crops from damage.

Sweden’s greenhouse farming sector has experienced a significant surge in demand over the past decade due to growing consumer awareness of sustainable and locally sourced produce. Vegetable cultivation dominates the market, driven by consumers’ preference for fresh and pesticide-free vegetables. The industry has embraced advanced technologies like automated climate control, hydroponic systems, and artificial lighting to enhance productivity and optimize resource utilization.

Organic produce is gaining traction. Consumers are increasingly seeking chemical-free and environmentally friendly products. Sustainable practices, such as integrating renewable energy sources and water recycling systems, are also gaining traction. The industry’s steady growth rate of approximately 5% annually is projected to continue over the next few years. Government support, export opportunities, and urban farming drive growth.

The floriculture market offers untapped potential, as cultivating flowers in greenhouses can cater to the growing demand for local and international decorative plants. Research and development opportunities are also available, with collaborations with restaurants and retailers providing a direct supply of greenhouse produce. Additionally, greenhouse farms can explore opportunities in agri-tourism and educational programs, creating additional revenue streams and promoting sustainable farming practices.

New Challenges for Organic Greenhouse Horticulture in Sweden

Swedish consumers increasingly favor organic food, and the government aims to boost food sovereignty and raise of organic food in public meals from 36% (2017) to 60% by 2030. However, there is a significant gap between the demand and production of organic vegetables. Only 4.9% of Sweden’s greenhouse area is used for organic production, mainly in containers and confined beds.

The recent European regulation revision requires a shift towards production in natural soil, impacting organic greenhouse horticulture. Phasing out confined beds and implementing soil-bound systems with crop rotations and fertility maintenance pose challenges due to climate constraints and greenhouse construction limitations.
