Abstract

Finnish rocks and soils are low in selenium:The concentration range is only 0.03–0. lOmg/kg. As a result, the selenium content of Finnish agricultural soils is low (0.2–0.3 mg/kg). Low temperatures and high humidity characteristic of the climate in Finland together with relatively low pH and high iron content of the soil favor deposition of selenium in reduced forms (1) known to be poorly available to plants. Thus, the geochemical and climatic conditions explain the fact that Finland is a low-selenium area both with regard to the soil and the biosphere.
