الوصف: Urban areas are characterised by land use change processes. Urban and peri-urban soils degradation increase at the different land uses, and the characteristic of each land use affecting soil carbon stock and, consequently, the role of soil as a CO2 sink. The aim of this work was to assess the effect of land use and soil management practices in urban and peri-urban soils in Vilnius (Lithuania). Studied properties were: Sand, Clay, Silt, Stoniness, bulk density (BD), pH, electrical conductivity (EC) and soil organic carbon stocks (SOCS). Ten samples were collected at depths 0-10 cm in 8 different land uses and soil management practices in the urban and peri-urban areas of Vilnius. Forests – Quercus robur, Acer plantanoides, Pinus sylvestris and Picea abies, grasslands – semi-natural grasslands (SNG) and managed semi-natural-grasslands (MSNG), both dominated by Taraxacum officinale, artificial grasslands (AG), and urban. SOC (t/ha) resulted significantly higher in Pinus sylvestris and Art. Grass than in Quercus robur, Acer plantanoides, and urban land uses. Urban land use recorded lower values of SOC (t/ha) than the other land uses except for Acer plantanoides. Land uses with high human intervention decline soil quality and affect the role of soil as a climate regulator.

مستخلص: Topsoil contents of cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn) and related soil properties such as pH and carbon (C) and nitrogen (N) contents were studied in the two main forest types of the Archbishopric forests in the area of the Jeseníky Mts., Czech Republic. Statistical comparisons were carried out between mature Norway spruce (NS) and European beech (EB) stands, separately for the forest floor (horizons FH) and the mineral (0–2 cm depth) soil. The FH horizons under EB showed higher contents of Zn, as compared to NS. In comparison, potentially higher contents of Cd were found under NS. The mineral topsoil under EB showed higher contents of Pb and Zn as compared to NS. In contrast, the pH was higher and the C:N ratio lower under EB, as compared to NS in both soil layers; the latter due to higher C under NS in organic horizons, while higher N under EB in the mineral soil. The results indicate that the species composition of managed forests may have conflicting impacts on soil quality and the accumulation and persistence of heavy metals in forest soils.

الوصف: Agricultural soils in savanna zones are very sensitive to compaction and crusting, which merits investigation because, with respect to rainfall, crusting occurs in them and no matter how thin the crusts become they prevent infiltration and root development. The aim of this study was to determine a general correlation between parameters of moisture, pH and zeta potential (ζ). The last two parameters were measured in the saturation extract of three soil samples dedicated to the cultivation and production of malting barley (Hordeum distichum), in order to develop a rapid and simple method of estimating the quality of this type of soil. The stability of the colloidal suspensions of soils, associated with colloids of organic matter, is diminished dramatically (increasing the ), to the extent that it decreases the biological crust cover (% CC) and clay content which subsequently decreases the textural composition and, therefore the soil moisture retention capacity. Land plots in the municipality of E. Zapata, demonstrated the worst textural conditions (lower % age of clay), lower moisture content, the lowest organic matter loading, higher bulk density and lower field capacity. All these aspects confirm that plots in the southern region of the State of Hidalgo, Mexico consist of more compacted soils which are less beneficial for growing barley.

الوصف: This diploma thesis inquires into the quality of the soils at 30 archaeological sites from the periods from Late Bronze Age to Early Bronze Age (1 250 - 450 BC). The aim of the thesis is to prove the dependence of the ratio of the cultivated cereals on the soil and other environmental factors in various regions. The secondary aim is the general observation of the changes, which could appear from this period until now. These changes are represented by the erosion, researched by various methods. The overview of the literature aims to the short description of the archaeological sources from the period, various approaches to the soil evaluation until present as well as information about the soil erosion and tools for its research. The conclusion of the thesis is that the ratio of the cultivated cereals depends mostly on the sea level, secondly on other environmental factors (included the soil quality). The results of the thesis are influenced by number of factors, discussed in the conclusion Keywords: soil quality, cereals, archaeological sites, perimeter of kilometre, soil erosion, late bronze age, early iron age
