Abstract

The Nordic working group for forest fertilization is a group of research workers from the Nordic countries Denmark, Finland, Norway and Sweden, which has been working on plant nutrition questions and forest amelioration problems. The group has met annually to discuss current problems, hitherto mostly concerning forest fertilization. In 1976 the question of future working forms came up, and the group decided to arrange a symposium on the subject Nutrient cycle in tree stands in 1977.

This symposium took place in Harjavalta and Ikalis in Finland from the 29th of August to 1st of September 1977. During the symposium 12 papers were presented, which are published in the following, either in full or as summaries of a given lecture. Part of the lectures are in English and part in Swedish.

The paper includes the following titles:

A bioelement budget of an old Scots pine forest in Central Sweden

Mobilization of plant nutrients in a Scots pine forest Mor in Central Sweden

Accumulation of organic matter and nitrogen on sand dunes following sand fixation and planting of dwarf mountain pine

Sambandet mellan torvmarkstyp och yttorvens näringshalt

Changes in the amounts of inorganic nutrients in the soil after clear-felling

Plant nutrient balance in decoration greenery cultivation

The effect of forest fertilization on primary production and nutrient cycling in the forest ecosystem

Förändringar i humuslagret efter skogsgödling

Balanserad näringsupptagning och behovet av gödsling i trädbestånd på näringsfattiga torvmarker
