    Soils and Flora in the Lower Oder Valley. This study contains the results of preliminary investigations concsrning the bog soils in the lower Oder valley, and its flora. In the course of laboratory and terrain investigations, the following sub-types of bog soils were determined, and characterized generally: 1) Peaty soils, 2) Silty-peaty soils, 3) Silty bog soils, 4) Mursh soils. These soils, with the exception of the mursh soils, are excessively moist because of their deep location — (most of them 0.3 m. below the sea level). Because of the large area they occupy, the peaty soils, and silty-peaty soils are of the greatest economical importance. In deciding on any economical steps especially after having settled the water conditions, the specific feature of these soils in view of their physical and chemical properties, response to fertilization, and their suitability as grazing land must be taken into account. The state of plant in this area did not change essentially as compared with that of fifty or thirty years ago. At present the following more important plant communities have been noted in the plant cover of the Lower Oder valley: 1) Plant Community of the type of: High sedges, 2) „ „ „ „ „ „ Reed sweet grass, 3) „ „ „ „ „ „ Meadow foxtail, 4) „ „ „ „ „ „ Chevings’s fescue, Meadow soft grass and Bird grass, 5) „ „ „ „ „ „ Manna grass, 6) „ „ „ „ „ „ Reed canary grass. The greatest economical importance represent the plant communities of the high sedges type, and the reed sweet grass communities which mainly cover the investigated area. It is the excessive moisture, and lack of any water movement even its stagnancy, that condition their occurrence. Plant communities of high sedges occur mainly on peaty soils. Plant communities of reed sweet grass occupy mainly silty-peaty soils. This is a general regularity which does not apply to smaller portions of meadows. These plant communities have a low forage value. The flora here, is exuberant what may be a further evidence of the potential fertility of the habitat. The analysis of plant and soil conditions indicates the necessity of settling the water conditions, what in turn might improve the qualitative composition of the flora itself. The character of the nature of the region would predespose it for maintaining meadows of the -liable to inundation-type. On some parts of the meadows, in more favourable water conditions, on siltypeaty soils there are possibilities of developing pasture husbandry.
