    Opis:
    The paper analyses the biomass and the deformation of the root systems of the Scots pine growing on an afforested post−mining area. Deformation of the root systems was detected in the pines growing on excessively compacted soils of a dump and in the pines growing in a sand mine pit with a shallow groundwater table. In both cases, the ratio of root biomass to aboveground biomass was considered too low, which might indicate a risk to stand nutrition and stability.

    Opis:
    In this article we analysed the influence of plant-based organic admixtures on the germination process of seeds and the early development of Scots pine Pinus sylvestris L. seedlings. The intensity of dumpin-off diseases within the culture was recorded after applying each of the admixtures. Organic material of nettle Urtica dioica L., softwood litter, hardwood litter and peat were applied to the nursery substrate in two ways, either as an admixture in crushed form or in granulated form. None of the introduced admixtures influenced the germination of seeds or the survival rate of pine seedlings positively. The best results were obtained with a substrate without admixtures used as a control, which is the most common nursery substrate. The worst seed germination rate was observed on the substrate enriched with the organic material from nettles. In pots with granulated organic material from hardwood litter, significantly more seedlings showed signs of post-emergence dermatitis. In all other cases, there was no clear difference between the crushed or granulated admixture in either germination or survival of seedlings. We furthermore demonstrated that the process of granulating plant material leads to an approximately 10-fold increase in the bulk density of the granulated substance, which translates directly into volume reduction.

    Opis:
    The presented research aimed to assess the influence of illegal dumping sites on changes in the phosphorus, nickel and lead content and the phosphatases activity in 0−20 cm top soil−layer. The samples were taken in the Bydgoska Forest (northern Poland) from four points. At plots W1 (debris and ceramic waste, glass, plastics, metals, textiles and used electrotechnical equipment), W2 (electrotechnical equipment, tyres and textiles) and W3 (wastes of organic origin from households as well as cut grass and residue from garden) samples were collected directly under illegally deposited landfill sites. The control plot (K) was located far from the determined waste landfill sites and beyond the range of their effect. We determined: organic carbon (Corg), total and available phosphorus as well as the content of total and available lead and nickel and the activity of alkaline and acid phosphatase. Uncontrolled landfill sites significantly influenced soil properties, which may lead to changes in the phosphomonoesterases activity of soil and the nutrient content. The study concluded that the composition of waste at W3 site had a less negative impact on the soils than at W1 and W2 sites. In the soil from landfills W3 we observed high phosphorus availability (AF 14.9%). The lowest resistance (RS) for alkaline and acid phosphatases was found in soils from the area of dumping sites W1 and W2, while the highest RS was determined for W3. The content of nickel and lead in the soil samples qualifies them into the category of soils with natural content of these compounds. Simple correlation showed clearly that organic matter was particularly implicated in the activity of phosphomonoesterases and the content of lead or nickel. Based on the clustering with Ward's method it was stated that cluster 2 includes two soil samples (W1 and W2) due to its lower phosphatase activity and organic carbon, available phosphorus and total lead content. A high variation in the activity phosphatase under study in soil W2 confirms a high coefficient of variation (>36%).

    Opis:
    The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.
