This paper assesses the impact of creosote and low-molecular-weight organic acids (LMWOAs) on the activity of acid phosphomonoesterase, alkaline phosphomonoesterase, phosphotriesterase, and inorganic pyrophosphatase in soil. The experiment was carried out on loamy sand samples with organic carbon content of 8.71 g·kg⁻¹, with the following variable factors: dosages of creosote: 0, 0.5%, and 2.5%; type...
The aim of the study was to assess the impact of long-term drainage on the morphology and selected properties of shallow peatland soils in microrelief. The study was conducted within strongly drained peatland (Długie Mokradło bog) located on elevated plateau in the Central Sudetes. The study area is covered by spruce stands introduced by man. Long-term drainage has changed morphology of study soils...
The aim of the research was to compare the effects of four to quaternary ammonium salts (QAS) with iodine anion: tetramethylammonium iodine [TMA][I], tetraethylammonium iodine [TEA][I], tetrapropylammonium iodine [TEA][I], tetrabutylammonium iodine [TBA][I]. The experiment was carried out on sandy clay loam samples with organic carbon content of 33.82 g·kg⁻¹, and pH in 1 M KCl 7.13. QAS were added...
Soil samples were collected at Al-Najaf governorate, Iraq and assessed for radon concentrations using CN-85 detector and uranium concentrations using CN-85 and CR-39 detectors. Also, Some radiation parameters due to radon concentrations were calculated. Radon concentrations were varied from (506.84) Bq/m³ to (1194.69) Bq/m³ with an average of (894.21±77.80) Bq/m³, while the radium content were varied...
In this paper, we investigate using of probit analysis for heavy metals (Pb, Cd, Cu, Zn, Co, Ni) toxicity assessment for spring barley (Hordeum vulgare L.) in sod podzolic sandy loam and chernozem soils. Estimation of the heavy metals phytotoxicity by means of PhLD50 value was suggested. The PhLD50 value is a doze of metal in soil that causes 50% reduction of plant biomass (mg·kg⁻¹). According to...
Pollution of soils with heavy metals is particularly dangerous to living organisms. Invertebrates are sensitive to changes in soil conditions, and, therefore, may be considered invaluable indicators of soil disruptions. This study has been undertaken to determine heavy metal content in the in soil and extracted soil fauna in two types of forest habitats of Niepołomice Forest and to establish their...
In this paper we presents the characteristics of selected physical and water properties of four arable soils situated within the range of the predicted depression cone of “Tomisławice” lignite open-cast mine. In the sampled soil material of undisturbed and disturbed structure following properties were determined: texture, particle density, bulk density, total porosity, hygroscopic moistures, maximal...
The purpose of the study was to verify the possibility of creation of reliable soil texture class (STC) maps of a topsoil based on a linear calibration of shallow (0-30cm) soil electrical conductivity (ECsh) with small datasets of soil samples with laboratory determined STC . ECsh values were calibrated against four datasets of soil samples. The smallest datasets (5-6 soil samples per field) were...
The article describes the results of field studies carried out in the period from April 2013 to May 2014. The study concerned the assessment of the magnitude of CO₂ emissions from marsh soils in the area of Czerwone Bagno (Red Swamp), which is a part of the largest complex of marsh in Poland. The authors used the closed chamber method to measure seasonal variability of net ecosystem CO₂ emission and...
The aim of the study was to evaluate the usefulness as a forest habitat, the technogenic soils developed by applying overlays containing organic matter in the waste substances, onto the layer of black coal ash. Properties of these soils, located in the power plant “Dolna Odra” in Nowe Czarnowo (West-Pomeranian province), were studied in 2015, i.e. 13 years after founding the experiment upon the use...
Risk elements distribution on agricultural soils in Slovakia is evaluated in this contribution. The measured results have been obtained on the basis of soil monitoring system in Slovakia which is consistently running since 1993 year. Risk elements have been analysed in extraction by aqua regia according to uniform analytical procedures in soil (Kobza et al. 2011). On the basis of the available results...
Festuca ovina was grown hydroponically on the Hoagland medium supplemented with CdCl2 (10 µg Cd ml⁻¹). Next, the plants were transplanted into pots (100 plants in pots) with uncontaminated soil and incubated under controlled conditions for 12 months. Approximately 420 µg Cd were introduced into 200 g of soil via the plant roots, the released cadmium being distributed between fractions with varying...
The aim of the study was to work out a method for quantitative assessment of soil nitrogen available for grassland sward (net mineralization), released in alluvial soils in Żuławy. Quantitative assessment of the pool of released nitrogen enables improvement of N management in fertilization of grassland sward and may contribute to the limitation of its dispersal in the natural environment. Studies...
