The article refers to metrological aspects of soil oxygenation, and describes both methodology and functioning of a new meter designed for the evaluation of the dynamics of reduction and oxidation processes (redox), as well as for pseudoquantitative estimation of the potential rate of oxygen diffusion in the soil, ODR.
A reflectometric meter (TDR) of soil moisture that can also be used for other capillary-porous substances has been described. The physical basis of the method together with the principles of the action have been discussed.
A new locality of Salvia glutinosa has been found in Kaczawskie foothills, in the north-western part of Grodziec village. The population consisted of 20 specimens. Most of the plants bloomed. This locality is probably anthropogenic.
Two main typological systems (forest habitat types and phytosociological classification) are used in forest research in Poland. The paper presents relationships between forest associations and forest habitat types in mountain environment of the Promotional Forest Complex ‘Sudety Zachodnie' (SW Poland). The results show that the link between these two topological systems is rather weak and ambiguous. This has strong implications for nature conservation in Poland, where forestry databases are widely used for inventories of protected habitats (in the sense of Habitat Directive).
