    Opis:
    The paper presents results of the studies on Cu, Mn and Zn content in forest soils of northern and central Poland covered by intensive monitoring. The investigated stands (Białowieża, Chojnów, Gdańsk, Krotoszyn, Krucz, Łąck, Strzałowo, Suwałki) cover various soil reference groups, including Brunic Arenosols, Cambisols and Stagnosols, developed from Quaternary deposits of different origin – glacial till, fluvioglacial sand and aeolian sand over fluvioglacial sand. The soils were sampled from O−horizons and mineral layers from the depths of 0−5, 5−10, 10−20, 20−40 and 40−80 cm. Analysis were performed using standard procedures in soil science and included basic properties (particle−size distribution, pH, organic carbon and total nitrogen), and the contents of Cu, Mn and Zn determined by ICP−OES technique after samples digestion in aqua regia. The noted contents of metals in the soils varied among stands, depending on origin of deposits and their textural parameters. The content of Cu in mineral horizons ranged from 0.0 to 20.0 mg/kg, Mn from 31.0 to 585.0 mg/kg and Zn from 3,6 to 255.0 mg/kg, whereas in O−horizons 3.0−29.1 mg/kg, 86.0−3627.7 mg/kg and 11.0−68.0 mg/kg, respectively. The noted content did not reach geochemical background in most cases, which is typical for forest soils of Poland. It indicates good ecological condition of the studied ecosystems and limited anthropopressure in this range. Vertical variability in the content of Cu, Mn and Zn constituted reflection of soil−forming processes and the influence of vegetation, as a key−factor in element's cycling in forest ecosystems. Strong influence of this factor is confirmed by higher concentration of the studied metals in O−horizon as compared to mineral soil. Moreover, a significant role of lithological discontinuities and water regime have been noted in some stands.

    Opis:
    The paper presents resent research results on the effect of aluminium (Al) toxicity on forest soils. It has been stated that with the present acidification level of the environment the toxic effect of aluminium compounds does not threaten the sustainability of stands. At the same time, the simulation of heavy acidification of soil environment has proved that mixed stands are more resistant to Al than pure spruce stands growing under the same conditions.

    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:
    The aim of the study was to investigate the structure of forest site types and of soil types of oak seed stands in Poland. The study was comparatively conducted with reference to sessile (Quercus petraea) and common (Q. robur) oaks. As in Poland the seed stands are established only in stands characterized by favourable both growth parameters and timber quality, it was suspected that the results of the study would enable to indicate optimal sites and soil units for oak breeding in Poland. The study was conducted on the basis of data obtained from the SEMEN database (www.bnl.gov.pl) which were broadened by descriptions of the investigated seed stands found in the Forest Data Bank (www.bdl.lasy.gov.pl). For both oak species, the research was conducted with reference to the two types of seed stands: permanent (WDN) and temporary (GDN). In total, 531 stands of Quercus petraea and 2043 of Q. robur located across whole Poland were investigated in the study. It was found that optimal soils as well as forest site types overlap for both investigated oak species only for fresh broadleaved forest (Lśw). For other forest type sites distinct differences for the oak species were found. The optimum for common oak were expanded towards the wet sites (moist broadleaved forest – Lw, and riparian forest – Lł), while for sessile oak towards semi−fertile mixed broadleaved forest (LMśw). It is interesting that seed stands of both oak species overgrow not only fine−textured soils, but significant share of them (ca. 50% area of Q. petraea and 15% of Q. robur seed stands) occurs on sandy soils (Brunic Arenosols mainly). It proves that Brunic Arenosols constitute forest sites enabling production of broadleaved forests characterized by favourable growth parameters and high timber quality. However, it is possible unless the soil have been podzolized by conifers due to podzolized Brunic Arenosols were rarely represented in the oak seed stands and, if so, the stands were characterized by relatively low site index. It was also stated that on podzolized Brunic Arenosols of fresh mixed coniferous forest (BMśw) admixture of oak should enable reducing negatively impact of conifers on a soil.
