| This study was part of a three-year (2004-2007) project entitled "Assessment and reduction of heavy metal inputs into Finnish agro-ecosystems" that was funded by the Ministry of Agriculture and Forestry in Finland. The main aim of this study was to estimate field balances of trace elements at the farm level on typical crop and dairy farms in Finland in 2004. Field balances estimated at the farm level showed that the balances of the harmful heavy metals, Cd and Hg, were often slightly positive leading in accumulation of these metals into the soil on the crop and dairy farms. Selenium indicated a highly positive balance resulting in enrichment of this element in the soil in both farming systems. Also, the Cu and Zn balances were positive on the dairy... |

| In Finland compound fertilizers have been supplemented with selenium (Se) since 1984. In 1998, the Finnish Ministry of Agriculture and Forestry raised the Se supplementation level in fertilizers from 6 to 10 mg Se/kg fertilizer. The most important sources of Se are milk, meat, and milk and meat products, which together cover nearly 70 % of the total Se intake. |
