    The authors give the results of ground as well as laboratory investigations carried out on the soils of the initial evolutionary stage which are forming on the grounds that more than 20 years ago were covered with alluvial muds from The Szczecin Lagoon. These investigations were carried out .in the years 1947—1960. An area of more than 400 ha was being examined. The area concerned was a longish strip stretching from the Stepnica Bay to the north-west along the shore of the Szczecin Lagoon, not far away from the water-way Szczecin Świnoujście. This area administratively belongs to the villages: Gąsierzyno and Piaski of the borough Stepnica in the Goleniów district. In the investigated area in places of formerly valueless swamp soils, (moor soils of various compactness and mouldy soils on the base of loose sands), and in places of former fallow lands (Dunes of sands, and former moorland) valueable arable and grassland was forming. The arable land forming on the investigated area was certain morphological similarity to humus made ground (sometimes clayey) or to tchernozem soils. The grassland soils forming on the shallow of alluvial muds correspond to the muddy moor soil; soils forming from pulpy alluvial muds, usually more moisty, have the characteristics of muddy swamp soils. The most impor-tant part among the soil forming factors nowadays plays the bedrock (Alluvial muds); the hydrological factors are of less importance. The evolution of the forming of soils is very slow. The moory process dominant prior to the evolution on the investigated area has been interrupted, and is now showing a marked tendency of disappearing. On the cultivated grassland soils the turfing process is now dominant. In the arable land an evolutionary tendency towards forming brown soils can be observed. Significant processes of exidization of the previously reduced chemical compounds, and the beginning of a shift of certain chemical ingredients into the inner parts of the profile have been identified. (Sodium, iron and aluminium oxide compounds). Soils forming from alluvial muds are now of a great agricultural value, and give rich corn crops, hay and roots. The amount of nutritional value and nutritional ingredients they possess is by far greater in comparison with moor soils that are not covered with alluvial muds. The authors think that the high fertility of these soils is mainly due to the great amount of organic substances, and the favourable physical properties, especially their high water-holding capacity. More detailed imformation on the investigated soils are being given in tables 1—4.
