Opis:
Przeanalizowano możliwe podejścia do problemu klasyfikacji jakościowej gruntów terenów rekultywowanych. Głównym utrudnieniem w ocenie bonitacji takich terenów jest brak ilościowych i jakościowych atrybutów procesów glebotwórczych oraz kontekst czynników decydujących o wartości użytkowej, odmienny niż w wypadku gleb powstałych w wyniku wieloletniego formowania w naturalnych warunkach litologii i klimatu. Doświadczenia z wieloletnich obserwacji terenów rekultywowanych wskazują, że odmienne litologicznie utwory stwarzają odmienne punkty startu oraz linie przebiegu w rozwoju procesów glebowych. Nie zawsze też grunty rekultywowane można traktować jako nieużytki. W artykule rozważono alternatywne wobec obowiązującego algorytmy oceny jakościowej gleb.
Possible approaches to the problem of the quality assessment of reclaimed areas have been examined. The main difficulty in the assessment of soil quality class in these areas is lack of qualitative and quantitative atributes of soil-formation processes and unlike in case of soil which evolved in natural lithologic and climatic conditions, there are no factors which determine the use. Long experience in monitoring reclaimed areas shows that different lithologic formations give a different starting points and lies in development soil-formation process. Reclaimed soils should not always be treated as wasteland. Other algorithms of soil quality assessment than the currently in use have been examined.

Opis:
Jakość gleb należy do najważniejszych czynników wpływających na poziom możliwych do uzyskania plonów w rolnictwie. Przez to jest istotnym elementem kształtującym dochodowość produkcji rolniczej na danym obszarze. Znajomość przestrzennego zróżnicowania bonitacji gleb na obszarach poszczególnych obrębów czy gmin ma wpływ na proces planowania rozwoju obszarów rolniczych. Element ten stanowi również ważną informację w procesie programowania prac scaleniowych, które to działanie odbywa się na poziomie samorządu wojewódzkiego. Dane te charakteryzują się bardzo długim okresem przydatności do wykorzystania, z uwagi na niewielką ilość zmian dotyczących klasyfikacji gruntów wprowadzanych do operatu ewidencyjnego, mających najczęściej charakter jednostkowy. Artykuł prezentuje wyniki analizy mającej na celu przedstawienie zróżnicowania przeciętnej bonitacji gruntów w poszczególnych obrębach powiatu dąbrowskiego, położonego w północno- -wschodniej części województwa małopolskiego. Jako źródło danych wykorzystano dane z operatu ewidencji gruntów i budynków pozyskane dla wszystkich obrębów wchodzących w skład powiatu. Wyniki przedstawiono zarówno w formie tabelarycznej, jak i graficznej.
The soil quality belongs to one of the most important factors which affects the level of possible to obtain crops in agriculture. Because of that, it is an important element in determining profitability of agricultural production in particular area. Knowledge of soil quality spatial differentiation in the areas of administrative parts or municipalities has an influence on the planning process for the development of agricultural areas. This element also provides important information in the programming process of land consolidation works, which action takes place at the level of provincial government. These data are characterized by a very long period of suitability for use, due to the small amount of changes relating to the soil classification inserted into ground and building registration, which mostly have sporadic event. The article presents the results of the analysis which aims to provide differentiation of the average soil classification in particular administrative parts of Dąbrowski district which is located in the north-eastern part of Małopolska voivodeship. The data of the ground and building registration were used as a data source, which were gained for every administrative parts of Dąbrowski district. The results of studies are presented in both tabular and graphical form.

Opis:
The research was conducted in 268 Scots pine (Pinus sylvestris L.) stands, separately on soils of different moisture – non−gleyic (215 plots) and gleyic (53). The site index (B) of every Scots pine stand was determine as mean height of the ten thickest trees per 0.1 hectare, recalculated for the base−age of 100 years. The results show clearly negative relationship between the pine site index and pH values, that is probably caused by positive impact of soil acidity on (i) mycorrhiza symbiosis and (ii) nutrients releasing from minerals in weathering processes. The optimum soil pH for Scots pine site index was defined as regarding ca. 4.5 pHH2O and 4.0 pHKCl. There was not stated any impact of CaCO3 content in soil parent material on pine growth. The soil depth was positively related to the site index only when non−gleyic soils were concerned. On gleyic soils any relation between soil depth and pine growth was found. The results showed that in different soil moisture conditions, properties of opposite soil zones play the key role for the pine growth. When pine was planted on non−gleyic soils, the site index was much more related to properties of deeper horizons and parent material than of topsoil, while on gleyic soils the site index was correlated to properties of surface soil layer mainly.

Opis:
The objective of the study was to analyse the site index (SI) of Douglas fir (Pseudotsuga menziesii) stands in relation to the forest habitat type, soil type and relief characteristics. We utilised infor− mation available in the Information System of the State Forests in Poland that included selected parameters describing habitat conditions and dendrometric characteristics of Douglas fir stands. In total, processed data referred to 863 stands with a total area of 1,644.45 ha. As the SI distribution was not consistent with the normal one (Shapiro−Wilk test, p <0.0001) we applied Kruskal−Wallis or Mann−Whitney tests to assess the significance of observed differences. Site index of surveyed stands ranged from 19.9 to 47.8 m, 32.6 m on average (standard deviation of 3.3 m). Douglas fir in northern and southern Poland characterized by higher SI than in western and south−western part of the country (HK−W=83.5; p<<0.001; fig. 2). Forest habitat type significantly distinguished analysed stands (HK−W=30.1; p<<0.001). The highest SI values were observed for mixed deciduous habitats (fig. 3). For more fertile fresh deciduous habitats Douglas fir achieved slightly lower site index, while the least fertile mixed coniferous habitats are characterized by significantly lower SI. Habitat moisture variant had no significant effect on the average SI values (HK−W=2.6; p=0.269). The highest values were found in strongly fresh habitats (32.8 ±4.1 m), while the lowest in the humid variant (31.7 ±3.4 m). We found significant influence of soil type (HK−W=23.2, p<0.001) even though the average SI values for each category were relatively similar (fig. 4). The highest values were observed for Cambisols (33.3 ±3.7 m), while the lowest for Arenosols (32.1 ±3.0 m). Particle size distribution is an important factor for Douglas fir site index (tab.). We found that the heavier material (the higher the content of silt and clay), the significantly higher SI values (HK−W=16.9; p=0.001). Mean SI for stands growing on former farmlands (32.0 ±3.3 m) and on forest areas (32.7 ±3.3 m) were not significantly different (ZM−W=1.73; p=0.084). There was no significant effect of the relief forms on site index surveyed Douglas fir stands apart from the fact that stands growing on slopes are characterized by significantly higher SI (ZM−W=1.99; p=0.047).

Opis:
The research was conducted in 268 pine stands on soils of sandy texture. In the paper 6 regression models for site index of Scots pine (Pinus sylvestris L.) were presented. The soil properties enclosed in the models explained to 40−60% of the site index variability. In the regression analyses, the following soil properties were found to be the best variables that described the site index: pHKCl, contents of fine textural fractions, content of K and N, CaCO3 content, soil moisture conditions reflected in gleying occurrence in a soil profile and a thickness of a solum or of a humus horizon (depending on the site moisture). The CaCO3 content was found to be a useful variable for the site index models only unless other chemical soil parameters were available. In such cases occurrence of CaCO3 in models reflects an impact of K and Mg soil content on pine growth that results from strong intercorrelations between Ca, K and Mg contents in the investigated soils. The site index was higher when pine stands were overgrowing gleyic than non−gleyic soils. In the presented regression models the difference was estimated to be about 1.5 m.

Opis:
The objective of the study was to determine the impact of selected soil properties on site index of oak (Quercus sp.) stands in the Międzyrzec Forest District (eastern Poland). We utilised data from the soil−habitat survey, which provided information about physical and chemical properties of soils and stand descriptions for 21 oak stands (tab. 1). The collected data served to determine site index (SI), defined as the stand top−height at the age of 100, and soil trophic index (SIG) that is a synthetic measure of the soil fertility. For SI and SIG distributions met the criteria of the normal distribution (Shapiro−Wilk test p−values equalled 0.118 and 0.297, respectively), we applied one−way analysis of variance, t−test and correlation analysis to determine the influence of the forest habitat type and moisture as well as soil properties and fertility measures on the site index of analysed oaks. The SI of investigated oaks ranged from 23.2 to 29.3 m, 26.5 m on average (tab. 2). It was significantly dependent on the site type (F=6.913, p=0.006) with the lowest values on oligotrophic habitat and the highest – on eutrophic one. No effect of habitat moisture content and soil type was found (t=–0.408, p=0.688 and F=2.599, p=0.076, respectively). The SIG values ranged from 20 to 36, with the average of 29.5 (tab. 2). Similarly to the site index, we found significant impact of the forest habitat type (F=5.384, p=0.015) on SIG values. Soil fertility and physical properties significantly influenced site index of the analysed oaks (fig.). We found positive correlation between SI and SIG values (r=0.566, p=0.007) as well as between SI and clay content (r=0.454, p=0.037). Chemical properties of the soils under studied stands seem to have less profound effect on site index of oak. The highest, but insignificant, correlations were found for recalculated acidity (r=–0.420, p=0.056) and magnesium content (r=0.400, p=0.071).

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.

Opis:
Forming of site index class of Scots pine (Pinus sylvestris L.) stands in relation to forest site types (including their moisture variants) and soil units (type/subtype and also – in minor extent – geological genesis of soil parent material) was investigated. The research was conducted in the Bolesławiec, Głogów and Oława forest districts (SW Poland) in 348 Scots pine stands. The values of the pine site index got higher with increasing fertility of soil units and better forest site type, but only when plots of sandy soils where concerned. Site index was found to differ significantly between fresh than moisture forest sites and soil units. The study results demonstrated that on fresh soils of sandy texture site index of Scots pine was distinctly related even to minor differences of site properties that concerned both its moisture and fertility. Scots pine, by height growth, does not fully utilize the great nutrient retention of fine textured soils that concerned both fresh and moisture pedons. Fine textured soils should be designed for eutrophic broadleaved tree species planting only, which would enable to fully utilize the trophic potential of such soils. The relation between the site index and geological genesis of sand forming parent material of soils was found. The differences in pine growth on sands of other genesis were assumed to be a result of different sorting and mineral composition of these materials.

Opis:
Impact of some chemical soil properties (OC and Nt content as well as C:N ratio in humus horizon; exchangeable cation stocks and base saturation) on site index class of Scots pine (Pinus sylvestris L.) was analyzed. The study was conducted in 67 plots, separately on sandy soils of different moisture – non−gleyic (51 plots) and gleyic soils (16). For every soil pit, stocks of particular cations were calculated to the five depths: 25, 50, 100, 150 and 200 cm. The distinct positive impact of N, K and Mg on the pine site index was stated. The strong influence of K was assumed to be caused by the strong effect of potassium on water economy of trees. The positive relation between Ca soil stocks and pine growth was also stated, however, the relation was described to be an indirect one. Probably it reflected the stated clear intercorrelation of Ca with K and Mg content. The only element that was determined as negative correlated to the site index was Na, that was especially distinct when topsoil Na stocks were concerned. The negative correlation was presumed to reflect sodium adverse effect on soil structure, that resulted in decreasing water sorption in topsoil and thus caused less favourable site moisture conditions for pine growth. The results showed that when refer to the soil depth, the strength of the correlation between stocks of particular cations and the pine site index was strictly dependent on soil moisture: on non−gleyic soils, on the contrary to gleyic, the correlation strength was directly proportional to soil thickness taking into consideration in statistical analysis.
