Selenium in Agriculture: The Finnish Solution Europe Has Ignored for 40 Years
While fertilizer prices in Europe explode, one nearly forgotten trace element can dramatically increase the value of your harvest – for just €2 per hectare. Finland has been using it since 1984.
Every farmer in Croatia knows the number that hurts: mineral fertilizer prices haven't returned to pre-war levels since 2022. What they don't know is that there's a trace element that costs almost nothing but can increase the nutritional value of their harvest up to 15 times. Finland has been adding it to every commercial fertilizer since 1984.
The Fertilizer Crisis Isn't Over
In the summer of 2022, natural gas accounted for up to 90% of variable costs in EU ammonia production. Result: About 70% of EU ammonia production capacity was shut down. The World Bank projects further fertilizer price increases for 2025.
Key insight: While NPK costs hundreds of euros per hectare, a trace element that demonstrably upgrades the entire food chain costs about €2 per hectare per year. It's called selenium, and virtually nobody in Europe uses it systematically – except the Finns.
Silent Problem: Europe's Soils Are Depleting in Selenium
Selenium (Se) is a trace element that plants absorb from soil in tiny amounts. Through the food chain – wheat → cow → milk → human – selenium enters every meal. No selenium in the soil, no selenium in the body.
Finland: An Experiment That's Worked for 40 Years
In 1984, the Finnish Ministry of Agriculture decided that selenium must be added to all commercial multi-nutrient fertilizers. What followed was a transformation of the entire food chain:

Selenium per hectare per year costs about as much as a cup of coffee. On the same area where you spend €500–800 on NPK fertilizers.
What Selenium Does in the Body
●Thyroid – without selenium, no conversion of T4 to active T3
●Immune system – critical for cell defense against oxidative stress
●Document – a proven selenium content in your grain is a measurable selling point
Caution: Selenium has a narrow therapeutic window. Doses above 20g/ha can cause selenosis in plants and animals. Carry out any application with a qualified agronomist and after soil analysis.
