English title: How forests should be studied in the future. Seminar on the research policy of the Society of Forestry in Finland.

The purpose of the seminar, arranged by the Finnish Society of Forest Science, was to instigate discussions which would bring up new approaches and research methods for studying forestry problems from both the biotechnical and socio-economical fields. Six papers were presented and over 70 opinions aired at the seminar.

The following points were considered especially important from the point of view of the promotion of forestry research

- Improving contacts between forestry and other branches of science and increasing international exchange of ideas and results.

- Improving the effectiveness of research work through sound planning

- Promotion and gaining benefit from diverse forms of research.

- Arranging the further education of researchers in order to improve the professional standards of researchers.

The PDF includes a summary in English.

English title: Effect of fertilization and irrigation on the ground vegetation of a Scots pine stand.

A mature Scots pine (Pinus sylvestris L.) stand growing on a site of the Vaccinium type in Southern Finland was fertilized with nitrogen-rich NPK fertilizer at a level of 150 kg pure nitrogen per hectare. The sample plots were also irrigated during four growing seasons. The total amount of irrigation during this period was 1,200 mm. Fertilization alone increased the coverage of grasses and dwarf shrubs. The culmination of the increase occurred during the second growing season after the start of the treatment. The rapid effect of irrigation on the coverage of ground vegetation was not so strong as that of fertilization. It was concluded on the basis of the developed growth model that the coverage of dwarf shrubs, especially Calluna vulgaris, was, however, increased with the fertilization treatment for a prolonged period. Fertilization and irrigation had no visible effect on the coverage of lichens and mosses.

English title: Predicting the bearing capacity of forest roads using a radar sounding.

Good correlation between radar reflection depth when using a FM-CW radar during winter and bearing capacity measurements during spring breakup was found. Therefore, it might be possible to evaluate the bearing capacity of forest roads using the radar sounding technique.

Eighty Betula nana samples were collected from three swamp sites. In the butt portion of the dwarf shrub the average number of growth rings was 12 and the average diameter of the sprouts 6 mm. The basic density of wood was 457 kg/m3 and that of bark 544 kg/m3. The proportion of bark was 32–38% of weight or volume. The vessel elements and fibres were short and their diameter small. The proportion of vessels was 15%, that of fibres 70% and that of rays 15%.
