In Lithuania, a typical Scots pine stand under the influence of wood ash and nitrogen fertilization, containing different treatments and the control, was analyzed. The study aim was to interpret the foliage and soil analyses, and to find possible indications in the soil-plant relation in the stand. The analyses of the foliage nutrient status in the Scots pine stand when wood ash with/without N was recycled to the forest showed that the significance analyses of changes in the nutrient composition in the soil and needles were the best initial tool for the response evaluation. The comparison of the nutrient concentrations with optimal amounts, critical...

The paper deals with throughfall and soil percolation in a sub-mountain beech forest situated at the Ecological Experimental Site (EES) Kremnické vrchy Mts. (the West Carpathian Mts., Slovakia). The research was conducted in 1988-2008. The throughfall was sampled at regular periods, both from the open plot (clear-cut) and from the plot with complete stocking, covered with a mature beech stand. The soil percolation was evaluated with soil lysimeters. In 1989 and 2004, the plots were treated with cutting - with the aim to reduce the current stocking. The average amount of throughfall was 772.2 mm in the open plot and 616.3 mm in the control. The amount...

The study analyses the growth of beech seedling fine roots and their development in the first five years. The research plots were established in 1997-2003 in community forests of Starý Plzenec (Western Bohemia, Czech Republic). The data are based on annual reviews of beech samplings extracted from surveyed plots. The whole root volume as well as the fine root volume is significantly (on a 95% significance level) growing during the first years after outplanting and there is not any disruption of growth immediately after outplanting.
Ecological requirements of wild service tree (Sorbus torminalis [L.] CRANTZ.) and service tree (Sorbus domestica L.) in relation with their utilization in forestry and landscape

Environmental conditions in sites with service tree and wild service tree are assessed and some ecological differences between them are also identified. Both species are regarded as prospective woody plants with a possibility of wider utilization in forestry and landscape arrangements. They are tolerant to direct sunlight and short-time water deficit in the soils, therefore they are suitable for the afforestation of arid and warm sites (even clear unstocked areas). They prefer soils with favourable physical characteristics and adsorbing complex with acid to neutral soil reaction. Both the mentioned taxa have valuable timber, so the potential of their...

The results of research on the production of raw timber assortments for the stands of poplar clones Robusta and I-214 in Slovakia are presented in this paper. Models of assortment yield tables were constructed, separately for each clone, in dependence on the yield class and stand age. The construction was based on the models of yield tables, stand assortment tables, models of external quality and damage to stems. Robusta clone produces by about 15-20% higher proportions of the highest quality assortments than I-214 clone. I-214 clone produces faster and higher proportions of average- and below-average quality assortments.
Occurrence of Ips duplicatus (Coleoptera: Curculionidae, Scolytinae) on pines (Pinus sp.) in the Czech Republic and southern Poland - Short Communication

Spruce is regarded as the only host plant of Ips duplicatus in Central Europe, whereas this beetle exceptionally occurs on pine in Siberia. Its occurrence on Pinus strobes and Pinus sylvestris was discovered in the eastern part of the Czech Republic and in southern Poland, where the population density of Ips duplicatus has been increased for a long time on Norway spruce. However, all cases concerned only single trees which were growing in forest complexes with spruce dominance. The most likely explanation is merely a consequence of the typical host plant shortage.
