Opis:: The aim of the experiment was to compare the rehabilitating effect of three factors that may improve the degraded and very poor soils formed from loose sands: dolomite liming, use of a multi−component fertilizer with delayed action (Silvamix W) and temporary introduction of an admixture Alnus incana into the Pinus sylvestris plantation. The results of the factorial experiment after 9 years indicate that the soils on which the experiment was established cannot be afforested without prior rehabilitation treatments. The activity of dolomite was most effective while of Silvamix − weaker. Alder survived in the plantation composition only when used in combination with dolomite fertilization, then its rehabilitating effect was apparent. Rehabilitation relying on the use of dolomite at a rate of 2 t/ha in combination with a 50% admixture of alder in the pine plantation is recommended to be used in practice.

Opis:: Forest management profitability can be raised by increasing stand productivity, which comprises improving wood yields and quality. The United States of America provides a good example of intensive management techniques applied on large scale to substantially increase forest productivity. Experiences of the U.S. South's forestry sector provide evidence that research−based intensive growth technologies are the key factor in ensuring adequate wood supplies and in effectively promoting sustainable management of the region's forest resource. Management treatments such as applications of fertilizers and herbicides have yielded lard productivity increases to date. Genetic improvement also has yielded large productivity increases along with improving stem straightness, wood properties, and disease resistance. Modern timber growth technologies already make possible doubling or even tripling current pine growth rates, while research progress indicates that current growth technologies can be improved even further.

Opis:: The aim of this study was to examine the effects of pruning the root system and different doses of nitrogen fertilization on the height and root collar diameter of 2-year-old beech seedlings (Fagus sylvatica L.). This research was conducted in the forest nursery Muchów (Jawor Forest District, regional directorate of State Forests in Wrocław) and two different pruning treatments (no pruning and at 12 cm depth) and nitrogen fertilization doses (25 and 50 kg×ha-1) were applied. Results from an ANOVA showed statistically significant differences between the two pruning treatments (p=0.000) as well as for the interaction of both treatment factors (p=0.019). Root collar diameter correlated with seedling height, both of which were significantly different for the two pruning treatments (p=0.000). No statistically significant impact by the nitrogen fertilization doses on seedling height could be observed (p=0.125). To conclude, we found that it is reasonable to reduce the doses of nitrogen fertilization to half the recommended amount, 25 kg×ha-1, if the root system is not pruned during the second growth year. Seedlings that do receive pruning should be fertilized using the recommended nitrogen doses.
