Tiivistelmä

The study showed that the levels of copper, boron, zinc and cobolt in organic soils are in general lower than those in mineral soils. However, for manganese it was quite the opposite. There were no clear differences found between the levels of molybdenum and selenium in different soil types. Trace element levels in different geographical areas varied considerably. Since the results of this study indicate that the trace element situation in agricultural soils appears to be following an unfavourable trend, the situation must be closely watched by means of cultivation studies. Good yields must be mainted if the food requirements of people and livestock are to be met.
