Opis:: The study deals with the criteria of forest site classification in forest planning taking special consideration of the significance of soils in forest site mapping. The analysis embraced two documents: Site−based principles of silviculture 2004 and Instruction of forest management. Part II. Instruction of differentiating and mapping forest sites 2003. It was pointed out that the soil criteria adopted in these two documents are inconsistent and incomplete and make it impossible for the appraiser to clearly distinguish forest sites on the basis of soil properties.

Opis:: The objective of the paper was to estimate i) the carbon accumulation in soils of different forest site types as well as ii) its changes with regard to the depth of the soil profile. The investigation was carried out in the Przedbórz Forest District (central Poland) on 43 study plots, including different forest sites – fresh coniferous forest (Bśw), fresh mixed coniferous forest (BMśw), fresh mixed broadleaved forest (LMśw) and fresh broadleaved forest (Lśw). On each plot soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of organic C and total N, particle−size distribution, the content of exchangeable Ca, Mg, Na and K, and hydrolityc acidity. The obtained results demonstrated that soils of Bśw, BMśw and LMśw sites characterized by higher carbon accumulation in surface horizon to 50 cm depth compared to the most eutrophic sites (Lśw). The rate of carbon accumu− lation in forest soils depend on the humus type which is connected with species composition of stands. Domination of Scots pine in stand affects the formation of ectohumus and leads to higher C accumulation in surface horizons on Bśw, BMśw and LMśw sites. In soils of Bśw, BMśw and LMśw sites carbon stored in the horizons to 50 cm constitutes 64−94% of the total carbon accu− mulated, while on the eutrophic sites (Lśw) this share amounts to 39−72%. The value of the total carbon stock in soils of fresh forest sites can be estimated on the basis of carbon stock in horizons to 50 cm depth.

Opis:: The morphology and properties of the post−arable soils that influence the trophic status of forest habitats on the Barycz river terraces (south−western Poland) were analyzed. The fieldwork included the characterization of the soil, tree layer, and the vegetation of the forest floor, as required for the forest habitat evaluation. In the collected soil samples, a set of physico−chemical analysis was carried out, that included: soil texture, bulk density, pH in KCl and water, total organic carbon, total nitrogen, hydrolytic acidity, base cations, and the content of plant−available phosphorus, potassium, and magnesium. Sandy post−arable soils in the Barycz valley have a thick, double− or triple−layered ploughed humus horizon, and the high stock of humified organic matter, nitrogen, and phosphorus, that emphasizes anthropogenic transformation of soils and differentiates them from the natural soils of river valleys. The diagnosis based on the soil trophic index (SIG) indicates generally lower trophic status (mesotrophic) as compared to the diagnoses based on forest floor vegetation and tree−stand (eutrophic status). The SIG model for the post−agrar moist valley habitats should be supplemented with the factors, which improve the apparent trophic status of sandy soils, including the thick humus horizon (post−ploughing) and shallow table of eutrophic ground water.
