Edvard Wibeck. (1929). Erwägungen bei Wahl von Kulturmethoden in der schwedischen Nadelwaldwirtschaft. Acta Forestalia Fennica vol. 34 no. 19 article id 7232. https://doi.org/10.14214/aff.7232
English title: Discussions on the choice of cultivation method in coniferous forests in Sweden.

In Sweden lot of state owned forests or earlier mining districts or districts of ironworks have been afforested during the last decade. The amount of afforested areas sinks from south to north. Afforestation has taken place also in privately owned forests.

The article discusses the common economic questions related to afforestation work and the biological viewpoints related to it. The best cultivation methods are presented for several common forest types, such as herb-rich forest types, moss-grown forests types, swampy forests with heavy raw humus and barren pine forest sites (lichen type).

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.

D. Fehér. (1929). Die Biologie des Waldbodens und ihre physiologische Bedeutung im Leben des Waldes. Acta Forestalia Fennica vol. 34 no. 14 article id 7227. https://doi.org/10.14214/aff.7227
English title: Biology of forest soil and its physiological meaning in the life of forest.

The article presents three studies about different aspects of the bio-chemical functions of forest soil. The three studies are i) research on microflora and microfauna of forest soils; ii) study on carbon nutrition of forests in relation to microbial functions of soil and effecting site factors and iii) study on nitrogen metabolism of forest soil. The results of the studies are summarized by every study.

The article discusses the meaning of the results for forest management in practice. The good biological and physiological condition of forest soil is important for the forest growth and it needs to be taken care in regeneration and other forest management. The natural regeneration seems to be better for soil functions. Favoring broadleaved trees as undergrowth enhances the biological processes of forest soil.

English title: Use of water of the trees and the moisture conditions in the soil.

The data has been collected in the dry heathy forests in Harjavalta commune in south-west Finland and in Sodankylä commune in Lapland in summer time 1918 and 1919. The aim to the study was to find out how does the water consumption of the trees affect the moisture conditions of the soil and how they are linked to the regeneration of the forest.

Trees in one age class have a certain spatial distribution: the greater the distance between trees the older the trees and the smaller the distance, the younger the trees. This seem to rather be due to the development of the root system and the nutrition intake of a tree than the competition for light. The moisture content of the upper soil layers is higher in the open areas than in the closed canopy stands. Hence there are more seedlings growing in open areas.   However, it is not clear whether the results apply for other forest site types as well, and more research is needed.
