Studies on the soil seed banks of fallow lands of different ages were carried out on poor soil abandoned fields and in a fresh coniferous forest in north-eastern Poland. The size and diversity of seed banks was studied with the seedling emergence method. Species abundance (i), density (ii), number of species from different biological groups (iii) and distribution and mean LI value (iv) were analysed as the function of fallow land age. It was found that: (i) species diversity, number of species and ln of density are linear declining function of the fallow land age; (ii) for approx. 25 years the share of diaspores of identified species groups has been relatively similar. Seed banks of 40-50-year-old fallow lands are dominated by Calluna vulgaris, while the seed bank of the old fresh coniferous forest is dominated by dicotyledonous perennials and grasses; (iii) within the first 50 years of succession the persistence of seed banks measured by the Longevity Index increases gradually.

The paper presents forest soil characteristics with respect to potential and actual water storage. The study involved three soil types (Haplic Podzol, Rustic Podzol and Rustic Brown) and three forest sites: dry coniferous forest (dry CF), fresh coniferous forest (fresh CF) and mixed deciduous-coniferous forest (mixed DCF). The potential and actual water storage was calculated for individual genetic horizons and for the 0-40 and 0-100 cm soli layers. The actual storage and potential water retention in the 0-40 and 0-100 cm soil layers as well as the SWC/FWC ratio can be used to relate soil water properties to soil and site types.
