Tiivistelmä

The report is part of the refertilization project started in 1972 in the Department of Peatland Forestry, the Finnish Forest Research Institute. Nitrogen, as well as phosphorus and potassium, are required in the refertilization of oligotrophic pine bogs. The need for nitrogen is less on fertile pine swamps, although in some experiments moderate fertilization with nitrogen in addition to PK gave the greatest stand growth increment. The use of micronutrients, especially boron, is recommended in the refertilization of fertile pine swamps. Methods for determining the need for nitrogen and micronutrients in refertilization should be further developed.
