English title: On classification of peatlands drained for forestry purposes.

The aim of the study is to find out 1) whether and how the original moor type can be found out based on vegetation regardless the phase of drainage; 2) whether the different phases of draining can be distinguished based on the vegetation; and 3) is it possible to classify the well drained moors into vegetation types that would reflect the productive capacity of the land.

The data consists of samples collected from ditched areas. There are 11 moor types from two climatic ditching zones. The results show that the original moor type can be determined based on vegetation, the phase of drainage can be determined under some limitations, and the classification for productivity can be done for practical purposes.    

The PDF contains a summary in Finnish.

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.   

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

K. Linkola. (1922). Zur Kenntnis der Verteilung der landwirtschaftlichen Siedlungen auf die Böden verschiedener Waldtypen in Finnland. Acta Forestalia Fennica vol. 22 no. 3 article id 7072. https://doi.org/10.14214/aff.7072
English title: Distribution of the agricultural settlements on different forest soils in Finland.

The paper studies the relationship of settlements to the forest types and forest soil. The observations have been done and data collected in southern Finland, around lakes Päijänne and Saimaa during summer 1917. Because of the shortcomings in the data, the results in the paper can be seen only as indicative.

The settlements have spread out firstly to areas of grove alike soils and herb-rich forests. The human settlements are still on these days concentrated on those areas. When more land is needed for agricultural purposes, the more fertile areas were introduced first. With forest type classification this means moving from herb-rich Oxalis-Myrtillus-type to Pyrola-type and to some extent Myrtillus-type. The more barren types are used as fields only very seldom. The differences in the fertility of the soils affects strongly the welfare and development of the people and the communes. 

The study shows that when considering the soil and vegetation, preconditions for agriculture are very different in different part of Finland. Also the climate and the geographical characters vary. To win more agricultural land, the fertile peatlands should be considered.

J. Valmari. (1921). Beiträge zur chemischen Bodenanalyse. Acta Forestalia Fennica vol. 20 no. 4 article id 7064. https://doi.org/10.14214/aff.7064
English title: Paper on chemical soil analyses.

The article tries to develop the method for defining the requirements of fertilizers for soil. The chemical soil analysis is also seen as the requirement for exact site classification based on height over age. The study is based on 1500 soil samples, one half of them from forest soils, the other half from arable land soils.    

The productivity of different forest types and the results of soil analyses are in line with each other. The most important growth factors are discerned.  Some shortcomings of the method are discussed.  Combining the soil analysis and the plant analyses of the sample plots seems to give the most accurate about the amount of nutrients that are available for the plants.

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.
