Opis:: The phosphogypsum dumps are one of the most toxic solid wastes of phosphoric acid, phosphate and phosphorus fertilizers manufacturing enterprises. In the article the possibility of remodeling of phosphogypsum dumps with using the Poaceae family herbaceous plants seeding was considered. On the basis of determination of growth parameters as well as sulfur and fluorine ions accumulation in the plants, the expediency of the dumps surface covering with a ground-covering mixture consisting of sand and sediment of wastewater in the amount of 10% or 20% by weight is established. In the dumps Bromus inermis Leyss., Dactylis glomerata L., Elytrigia pseudocaesia (Pacz.) Procud., Festuca arundinacea L. and Festuca altissima L. are the most suitable plants for cultivation.

Opis:: The purpose of this paper was to assess the impact of grazing methods on the indicators of vegetation and soil cover of pastures located in the semi-desert zone in the West of Kazakhstan. The experiment was carried out on 3 pastures with different grazing methods, and a reference plot with no grazing served as a control variant. Transects measuring 100*50 m were laid on pastures, where all regime observations of herbage indicators were carried out. Soil samples were taken in layers of 0–10, 10–20, and 20–30 cm with 3-fold repetition. The lowest indicators of yield (0.38 t/ha), projective coverage (45%), species composition (12 pieces), and herbage height (22 cm) were established on pastures with intensive grazing. Intensive grazing also reduced the quality of the soil, where a low content (0.83 percent) and reserves of humus (34.19 t/ha) and phosphorus (0.65 mg/100g) were found, and the soil compacted to 1.38 g/cm3, its structure decreased to 53.15%, the soil degraded to the 3rd degree and became moderately solonetzic. High values of vegetation and soil cover indicators were obtained on pastures with rotational grazing. In the rotational grazing variant, the yield difference compared to the control variant amounted to 0.41 t/ha, and the yield of feed units (0.07 t/ha), digestible protein (0.011 t/ha), and exchange energy (1.08 GJ/ha) had increased. A higher content of available phosphorus (0.95 mg/100g of soil), agronomically valuable structural aggregates (67.55%), a looser density (1.24 g/cm3), and weak salinity were found in the soil cover of rotational grazing pastures.

Tytuł:: Vegetation of industrial waste landfills within the agglomeration of the capital city of Warsaw

Opis:: This study presents the results of examination of the vegetation on the waste landfill of ArcelorMittal-Warszawa steel mill and the furnace waste landfill of Siekierki Power Station, both sites in Warsaw. The presented analyses of the field research contain detailed floristic-phytosociological data as well as botanical and ecological evaluation of the identified plants. The vegetative structures, together with the succession trends of the vegetation cover of two examined landfills, have been shown. Ecological habitat adaptations of plants and their spatial structure have been evaluated. The inventoried flora has been subjected to taxonomic, syntaxonomic and ecological classification. 154 plant species from 48 taxones in the range of families have been identified. Families characterized by the biggest abundance of species were: Compositae, grasses and Fabaceae. More than half of the live forms indentified were hemicryptophytes. The vegetation of two landfills has been dominated by synantrophic communities (Stellarietea mediae, Artemisietea vulgaris, Molinio-Arrhenatheretea), with apophytes being in the largest number. With the use of ecological indicators a broad ecological tolerance of the majority of species toward ecological factors has been observed.
