The paper is a report on the volume weights of the ash-free, dry peat on the cultivated Sphagnum bog at Leteensuo found in connection with different degrees of nitrogen fertilization. The volume weight attained higher values under nitrogen fertilization than in the treatments with mere potassium and phosphate fertilization. As the volume weight of peat also increases with increasing humification, the conclusion was drawn from the results that nitrogen fertilization has favoured the humification of Sphagnum peat.
