    criteria of forest site classification
    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 numerical valorisation of soil quality is based on the determination of a set of soil properties adjusted to a given soil function in the ecosystem. The obtaining of an index is based on: determination of soil properties, their conversion into abstract numbers called indicators, index calculation and its practical application. The first proposal of a forest soil quality index was the Forest Soil Trophism Index – ITGL calculated for the soils presented in the Atlas of forest soils in Poland. The calculation of the ITGL was based on the following soil properties: percentage share of very fine sand and coarse silt fraction (Ø 0.1−0.02 mm) and silt and clay particles (Ø <0.02mm), reaction, sum of exchangeable bases and organic matter decomposition degree, content of skeletal parts. Its variability in the forest soils of Poland oscillates between 6.0 and 43.0 and its application in the valorisation of forest sites is multidirectional.

    Opis:
    The aim of this study was to present the relationship between soil properties and biodiversity indexes in upland fir (Abies alba) forest associations (Abietetum albae). Our study was conducted in six areas representing the growth conditions of upland fir forests and the research plots were located in the Roztoczański and Świętokrzyski National Parks as well as Przedbórz, Radomsko, Piotrków and Janów Lubelski Forest District. On every plot, the topography was described, soil cores were examined and samples for laboratory analysis were taken. The following characteristics were determined for the soil samples: pH, C, N, Ca, Mg, Na and K content, particle size, exchangeable acidity, aluminum content and hydrolytic acidity. Additionally, enzyme activity in the soil samples (urease and dehydrogenase) was measured. In each test area, the stand characteristics were measured (diameter at breast height and height) floristic characteristics were described and the biodiversity indexes (Shannon, Simpson and Margalef indexes) were calculated. Different soil types (Gleysols, Brunic Arenosols, Gleyic Podzols and Hyperdistric Cambisols) were recorded for the investigated forest stands and the soils were categorized according to soil texture, C content, enzyme activity and different humus types (moder-mor, moder, moder-mull). The upland mixed coniferous forest sites were characterized by lower biodiversity indexes (2,6 Shannon index; 0,72 Simpson index; 4,9 Margalef index) while the upland mixed broadleaf forest sites showed higher indexes (3,3 Shannon index; 0,87 Simpson index; 9,4 Margalef index). The site index obtained for the fir stands confirmed these results.

    Opis:
    On 127 experimental plots were classified into different forest site types according to vegetational criteria, 16 main soil properties were analysed and their content in a 100 × 100 × 150 cm soil lump was calculated. The expert system and the linear discriminant analysis showed different soil properties and their groups enabling stronger or weaker division of the examined sites into forest site types. The content of 0.1−0.02 mm fraction, the content of <0.02 mm fraction, the concentration of H+ ions as pH reaction in H20 and the content of mobile N were pointed to as those which better distinguish coniferous forest (B) from mixed coniferous forest (BM), mixed coniferous forest from mixed broadleaved forest (LM) and mixed broadleaved forest from broadleaved forest (L). The other soil properties in the expert system showed a weaker strength in differentiating the examined sites into different forest site types according to vegetational criteria.

    Opis:
    The correct assessment of the site conditions is the basis of the good management of forest areas. The aim of this study was to find a set of soil properties, which allow separating the diverse sites in terms of the soil productivity. We used 180 locations in the Carpathians and the Sudety Mountains for testing. The study plots were located in transects from the foothills to the top along the slopes, taking into account the variability of site conditions, geological substrate and exposition. The index was calculated on the basis of the content of <0.02 mm particles, the sum of exchangeable base cations, soil acidity and the ratio between total N content and organic C in the humus−mineral horizon. The soil trophic index for mountain areas (SIGg) that include the climatic factor was introduced. The factor is defined as the 650/altitude ratio for a given point above sea level. In the mountains, the content of <0.02 mm fraction, the sum of exchangeable base cations and soil acidity were determined in the column of 1 m² of the soil cross section and depth of 1 m (1 m³ of volume) due to the lower depth of the soil profile. The SIGg correctly separates soil of different productivity as the properties closely associated with the stable elements of the soil, expressing its production and properties, which reflect the current state of the soil environment, were used in the construction SIGg.
