Studies on morphological features and chemical composition of Ap horizons of soils located on gentle Narew valley-sides were carried out. The Luvisols with a texture of loamy sands and sandy loams are developed on the slope shoulder while the Mollic Gleysols of a similar texture with deposits to 110 cm thick are located on the footslope. The soil particle size distribution and total nitrogen (TN),...
The studies were carried out in central Poland. Total organic carbon (Corg), total nitrogen (Nt) andCof humus fractions in uppermost soil horizons were analyzed in afforested meadow soils in first and fifth year of afforestation (2 profiles) and compared to about 70-year-old continuous forest soils. Soil was collected from 0-5, 5-10, 10-15 and 15-20 cm layers depth. The results showed that the soil...
This paper describes the fractional composition of humus substances and physico-chemical properties of ectohumus horizons in forest soils (Haplic Cambisols (Distric) and Albic Podzols) developed from various parent materials and in various forest sites: mountain mixed forest witch beech tree, spruce forest witch spruce monoculture, mountain mixed forest witch beech, sycamore maple and larch and mountain...
This paper describes the fractions of humus compounds present in the organic and mineral horizons of the forest soils in the area of the Karkonosze Mountains. Soil profiles that represented the mountain Podzols and Dystric Cambisol were located on the northern slope along an altitude gradient from 890 to 1255 m a.s.l. Two soils were located under the spruce forest, and one in the subalpine meadow...
The aim of study was to assess the influence of cultivated plant species (potato and rye) in monoculture and in crop rotation as well as the impact of the applied fertilizers on the content of soil organic carbon which was extracted by a 0.004 M CaCl2 solution (EOC). Soil samples were taken from a long-term static fertilization experiment carried out in Skierniewice, Poland. The content of TOC in...
The aim of the study is to evaluate differences occurring in the soil humus horizons between different types of forests. Soil samples were collected from spruce monoculture and natural beech sites within the lower montane zone in the Tatra Mountains. They were analyzed for organic carbon (OC), loss on ignition in ectohumus horizons, pH, fractional composition of organic matter and cellulose decomposition...
In this study we compare the effects of two contrasting grazing regimes (time-controlled grazing (TCG) vs set-stocked grazing (SSG)) on selected parameters of soil biological health. The purpose of the study was to evaluate these soil parameters as potential indicators of soil health and thence sustainable soil management. Two parameters, viz., arthropod biological diversity and soil respiration were...
The paper presents the results of research into the activity of alkaline and acid phosphatase against selected chemical parameters in the selected humus horizons of arable soils of the Unisław Basin. It was found that the soil demonstrated a higher activity of alkaline phosphatase by 35% on average, compared with the activity of acid phosphatase, which is due to the high soil richness in CaCO3. Considerable...
The aim of the investigation was the estimation of sulphate sulphur in soils in the Podkarpackie Province. The content of sulphate sulphur within the soils developed on flysch works subject to strong spatial variability of 0.87 g kg-1 in the Przemyoel Foothills to 2.00 g kg-1 in the Cieżkowickie and Strzyżowskie Foothills. The content of sulphate sulphur in soils is positively correlated with the...
The study has been carried out in the experimental field of the Centre for Ecological Research of the Polish Academy of Sciences, PAN, located in Dziekanów Leoeny (north of Warsaw). Six hundred lysimeters were installed covering the experimental area. The surface of the experimental plots (both lysimeters and their vicinity) was sown with either one grass (Festuca rubra) on half of the area, or with...
The aim of the study has been to assess the influence of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies) admixture in European beech (Fagus sylvatica) stand on some properties of organic and humic horizons of Dystric Arenosols and the intensity of biological turnover. The studies were conducted in northern Poland in Łysomice Forest Subdistrict (Forest District Leśny Dwór, Regional...
The aim of the study has been to assess the role of litho-morphogenetic, hydrologic and anthropogenic factors influencing spatial variability of sorptive and buffer properties of the soils of erosional-denudational valley incised in hollow sediments flat-dipping glacial till in the area of Sławieńska Plain. Parent material properties, water - as a causative agent of erosion and ions carrier, as well...
The aim of this study has been to determine the level of contamination of the soils and grass swards abutting the selected busiest traffic routes of Lublin City with heavy metals: Cu, Cd, Cr, Pb, Zn. 36 surface soil samples (0–20 cm) and grass swards (roots and above ground parts) were collected. The goal of the research has been to assess the impact of road traffic on the content of heavy metals...
The aim of the study was to evaluate the total content of zinc in the fractions separated from the soils located in two transects on the moraine slope of the Siedlecka High Plain (some situated above and some beneath the underground municipal landfill site). The highest total content of zinc was detected in the soils situated beneath the underground municipal landfill site. The sequential fractioning...
The research has aimed to determine the impact of fire on pools of soil organic matter and water retention in pyrogenic soil in meadow and forest areas. The following soil samples have been represented: moorsh, peat-moorsh, mineral moorsh and peat. The soil horizons represented: strongly dried peat-moorsh soil, medium-deep (MtIIc1 and MtIIIc1), mineral moorsh soil (Me11) and moorsh soil. Soil horizons...
The aim of the study was to evaluate urban forest soil resistance to degradation caused by intensive anthropopressure by determination of buffer capacity. The study covered six soil profiles located in two forest complexes situated within the boundaries of the City of Lublin with reference to benchmark profiles. The material compiled for the study represented loessive soils and rusty sandy soils....
For modelling the flow transport in unsaturated conditions, we can use hydraulic properties which are expensive and time-consuming to be obtained directly because of high variability and complexity of soil systems. Few studies have been done about pedotransfer functions (PTFs) in smectitic soils. Moreover, the utility of fractal parameters in the prediction of soil water retention curve (SWRC) have...
Peat deposits can be considered as archives of environmental changes and indicators of anthropogenic pollution. The character of element accumulation, the potential of metal ions to bind functional groups in the peat structure, the pH reaction, the presence of oxygen, the complexing compounds and inorganic ions are the main factors governing peat ability to accumulate major and trace elements. The...
Organic carbon stocks (SOCs) were determined in 14 pedons of the Little and Silesian Beskids (7 from each one: arable land and grassland) and compared with the C-stocks occurring in the soils of Ciężkowickie and Silesian Foothills. They were similar to SOCs in the soils of the Silesian Foothills, but significantly higher than in the soils of the Ciężkowickie Foothills. The participation of SOCs 0–30...
