Opis:
Changes in chemical compounds and in ectomycorrhizal structure were determined for Scots pine growing on post agricultural soil lying fallow for 3, 6 and 15 years, after amendment with pine sawdust. Soil without any amendments was used as the control treatment. Comparing the ectomycorrhizal structure 15 years after the application of pine sawdust revealed no significant differences in abundance or species richness between soil with and without organic enrichment. The results showed that the ectomycorrhizal status depends on soil conditions (soil pH, nitrogen content), which remain unaffected by saw dust application. In all treatments, the most frequently occurring ectomycorrhizae genera were Dermocybe, Hebeloma, Suillus, Tomentella and Tricholoma. Two species (Paxillus involutus, Amanita muscaria) were specific to the control plots that lay fallow for 15 years.

Opis:
The main objective of the study was to analyse the influence of compost produced from urban green waste, sewage sludge from municipal treatment plants and horticultural peat on changes of selected chemical and microbiological parameters of forest soil reclaimed after a fire. Soil samples were collected one and two years after the components had been applied to the soil. The results from experimental sites were compared with those from control samples. In the soil samples the following parameters were determined: content of carbon and nitrogen, reaction, hydrolytic acidity and the total amount of alkaline cations. Also the total number of bacteria and fungi, including moulds and yeast, was analysed. A year after components application, pH and the number of yeasts and moulds in the soil increased. After two years the content of nitrogen and the total number of bacteria in the soil increased as well. The most beneficial effect on changes in soil properties had the application of sewage sludge, which manifested itself in a decrease of the C/N ratio. This indicated the suitability of sewage sludge in reclamation of poor forest habitats. Peat underwent the slowest mineralization among all the organic components applied to the soil.

Opis:
We analysed changes in soil chemical properties (pH, C:N, N, P, K, Ca, Na) inside two forest areas chosen for renewal (Lubartów A and B) and within one post-agricultural site (OEwierczyna) designated for afforestation with Scots pine. The experimental plots were located in areas known as persistent cockchafer grub spots. The Lubartów A site was not fenced and showed signs of wild boar activity. Analyses were carried out in the autumn of 2011 and spring 2012, prior to pine sawdust application to the soil and before tree planting, respectively, and again one year later in May 2013. Precipitation as well as air and soil temperatures were recorded throughout the experimental period. We found that soil temperature and humidity, determined by changes in weather, differences in soil chemical properties between forest and agricultural sites as well as sawdust treatments differentially affected soil reaction, C:N ratios and nutrient content . In the unfenced area (Lubartów A), the content of nutrient forms available to plants decreased no more under sawdust treatment than under control conditions. In the remaining areas, sawdust treatment caused an increase or no change in soil concentrations of the investigated nutrients. Under suitable temperature and humidity conditions, sawdust can represent a significant source of energy-rich compounds promoting diversified edaphone activity, which appears to be the main reason for changes in soil nutrient content.
