This is a working paper. It presents the laboratory experiments with soil samples from northern Finland, in which the precipitation of iron (Fe) was tested with limewater (Ca). There was no clear difference between samples with limewater and samples without limewater. However, the lime prevented the infiltration of iron almost totally.
The mineral content of soil effects the forest growth and yield and hence it is of interest for forestry. More research is needed both as field experiments and in the laboratory.
