In soil profiles from a series of uplands of different site types bulk density, density of solids and porosity of soil were clearly related to soil organic matter content and its distribution in the soil profile. Soil organic matter contents were also strongly correlated to effective cation exchange capacity (CEC) and soil acidity. Site fertility was primarily related to the fine fraction (ø<0.06 mm) content in the C horizon and related properties (i.e. CEC). In the humus layer, the content of exchangeable bases and base saturation most strongly related to site fertility.

The aim of the study was to find out firstly whether there are differences between the etheric oils of botanically alike but in different climatic conditions growing trees, and secondly whether the oils from alike trees are also alike. This article shortly describes the chemical composition of Pseudotsuga Douglasii cecian Schwerin and Pinus Murrayana Engelm. The needle samples are from Mustiala Arboretum.
The first mentioned contains α-pinene, camphene, bornyl acetate, probably also limonene but no geraniol. Pinus Murraya’s oil contains pinene, camphene, borneol and cadinene.
The PDF contains a summary in Finnish.
