Benefit: Improved nutrient balance

About 3% of the nitrogen input in Finnish agricultural soils originate from biological nitrogen fixation. It equals to 8 800 tonnes of nitrogen annually.

In other habitats nitrogen fixing vegetation is vital in order to gain sufficient amount of nitrogen compounds first for plants and secondarily into the whole food network.
