Abstract Temporal changes in labile soil Cu, Mn and Zn were measured for up to 23 years after conversion of a boreal forest to the following crop production systems: (i) continuous barley, (ii) continuous legume and (iii) continuous bromegrass for hay, and (iv) barley/legume-bromegrass hay rotation. Decreases in labile Mn and Zn were greater than can be accounted for by crop offtake except for the continuous grass treatment. Some Mn and Zn was probably converted to less labile forms due mostly to reduction in soil organic matter associated with soil cultivation and some cropping systems. Labile copper was increased slightly with time under agriculture.
