Opis:
The aim of this study was to assess the influence of silver nanoparticles (AgNPs) on the number and diversity of microbial community in different environments (soil extract, water, sewage), and to determine whether the environment inhibits or accelerates the influence of AgNPs on moulds. AgNPs (45 ppm) present in the environment decreased bacterial (91%) and fungal (33-85%) numbers, and eliminated some strains, e.g., Alternaria alternata and Cryptococcus laurentii. Based on the biomass growth of Aspergillus niger and Penicillium chrysogenum in a medium with AgNPs and the environmental samples, it was noticed that environment can enhance (soil extract) or inhibit (sewage) antifungal activity of AgNPs.

Opis:
Soil urease is an enzyme catalyzing the hydrolysis of urea. The activity of the enzyme influences the content of ammonia ions in soil and thereby the fertility of the soil. 5-hydroxy-1,4-naphthalenedione (juglone) is a compound which inhibits urease. The compound is released by trees of the Juglandaceae family (walnut trees) and is present in their leaves, roots, husks and fruits. The aim of the study was to determine the effect of walnut trees on the activity of soil urease. Urease activity was determined in the soil beneath the tree crown and beyond.It has been shown that soil urease activity is higher in the area outside of the tree crown than beneath it. Less active urease slows down the natural nitrogen cycle resulting in decreased soil fertility. The lower soil fertility slows the growth of plants. This shows non direct influence of juglone on the growth of plants in the vicinity of walnut trees.The greatest difference in urease activity beneath and beyond the crown was observed near the oldest tree. This indicates that the development of the crown and root system increases the amount of secreted juglone.Soil active acidity and exchange acidity were measured. The study did not show a significant correlation between soil urease activity and soil acidity in the observed pH range.

Opis:
The concentrations of available and total Mn were determined in the soils of three different forest ecosystems, i.e. a maquis forest, a beech forest and fir one. The concentrations of total Mn in the deeper mineral horizons reflected the type of patent material, but in the surface layers, the more acidic soil (in the beech forest) had the higher concentrations. This was due to the high concentrations of Mn in the standing leaves and litterfall of beech trees, which brought about high litterfall fluxes of Mn in that forest. However, the concentrations of (DTPA) available Mn was significantly higher in the soil under beech only in the 0–10 cm layer, whereas the fast decomposition of organic matter in the Mediterranean zone resulted in higher concentrations of available Mn in the Ofh soil horizon of the maquis plot. The available Mn did not correlate with soil pH. These findings mean that high concentrations of available Mn do not always entail higher uptake. The soil pH played a predominant role for the high concentrations in the vegetation of the beech forest.

Opis:
The composting process is a natural method of waste disposal. Decomposition of organic matter occur with the participation of various groups of microorganisms. Using glyphosate-based herbicides aims to reduce agricultural losses. Biodegradation of glyphosate in soil is obtain with bacteria and fungi and may affect their functioning. The purpose of this study was evaluating the effects of glyphosate on bacterial diversity during composting and to monitor potential changes in community structure and species abundance. The addition of glyphosate did not affect the morphology of the tested groups of bacteria and did not cause changes in the morphological structure of fungi. Sampling after 10 minutes, 24 hours, 48 hours and 72 hours showed that the abundance of bacterial colonies changed over time compared to the control groups. However, the results suggest that the addition of glyphosate is insufficient to influence the composting process, thus disturbing the specific biocenosis.

Urbanization is the cause of many changes which is taking place in the environment, including those found in the catchment. A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 15, Polimag 306 and Travit at the rates of 0.5; 1.0; and 1.5 g N per pot. The total forms of nitrogen were determined in dry matter of perennial ryegrass with the use of ASA method. The contents of these elements were higher in the fertilized variants as compared to the control. No significant differences were found among the contents of investigated elements compared in plants treated with different multicomponent fertilizers. The chemical analyses indicated that increasing rates of the fertilizers applied enhanced the contents of nitrogen.

Heavy metals in soils may be a potential source of danger to plants and groundwater, and consequently - can be incorporated into the food chain [Karczewska et al. 2008 Kabata-Pendias 1993]. Downloading trace elements from contaminated soils by plants often exceeds their physiological needs, with the result that an excess of these elements in the soil can act phytotoxic.

Opis:
Soilless culture is used for the growing of vegetables and ornamental plants. In this technology plants in inert medium are frequently cultivated. However, in order to stabilize the concentration and the pH value of the solution in the root zone and in order to adjust the substrate moisture, the volume of nutrient solution must be higher than the nutritional requirements of plants. In result, there are significant leakages of nutrient solution to the soil. The aim of the presented research was the investigation of chemical properties of soils in the greenhouses where soilless culture technology is used for ornamental plant cultivation. In comparison with control soils, the 1:2 soil water extract from greenhouse soils showed a higher electrical conductivity. In result of nutrient solution leakages, in the soil increased the concentration of almost all nutrients and particularly of potassium, nitrates, magnesium, while the content of phosphorus, sulphates and of microelements decreased in a lesser degree. The highest threat results from the easy translocation of NO3-N. The degradation rate of soil environment depended primarily on the length of greenhouse utilization.
Uprawy bezglebowe wykorzystuje się do uprawy warzyw i roślin ozdobnych. W tego typu technologiach w celu ustabilizowania stężenia i pH pożywki oraz wilgotności strefy korzeniowej, ilość stosowanych roztworów musi być większa od rzeczywistych wymagań rośliny. Efektem tego są znaczne wycieki pożywki do gleby. Celem badań była ocena właściwości chemicznych gleb w szklarniach, w których są prowadzone uprawy bezglebowe roślin ozdobnych. W porównaniu z próbkami gleb kontrolnych (trawnik), wyciąg wodny z gleb szklarniowych miał większą konduktywność elektryczną. Na skutek wycieków pożywek w glebie wzrastała koncentracja niemal wszystkich składników, a w szczególności potasu, azotu azotanowego i magnezu, w mniejszym stopniu fosforu, siarczanów i mikrślementów. Największe zagrożenie dla środowiska wynikało z łatwego przemieszczania się N-NO3. Tempo degradacji środowiska glebowego zależało przed wszystkim od długości okresu eksploatacji szklarni.

Opis:
The objective of this study was to determine the effect of cobalt on the content of total organic carbon, total nitrogen, the available forms of phosphorus, potassium and magnesium and the C:N ratio in soil, following the application of neutralising substances. The effect of cobalt in soil was tested on oats (Avena sativa L.). In order to limit the effect of cobalt, the soil was enriched with neutralising substances, i.e. manure, clay, charcoal, zeolite and calcium oxide. In the series with no neutralising substance, the increasing doses of cobalt only caused an increase in the amount of the available potassium, and the highest Co dose favoured an increase in the organic carbon content and a wider C:N ratio in soil. All the substances affected the content of the available potassium in soil, with charcoal, and especially manure, contributing to its elevated accumulation. Besides, manure fostered a growth in the soil content of the available phosphorus, charcoal - the content of organic carbon and the available potassium, and zeolite - the total nitrogen content, while calcium oxide promoted a higher content of total nitrogen and the available phosphorus. Clay and charcoal (unlike zeolite) caused the widening of the C:N ratio in soil.

Opis:
The purpose of the research presented in the paper was to conduct the heavy metals contents in area of tannery plant and to determine their influence on soil microflora. The soil samples were collected to this purpose from the area, which was surrounded by the industrial buildings from one side (tannery, galvanic plant and chemistry plant) and by river Wilga and two small ponds from three remaining ones, which supposedly collect the sewers from these plants. The collected samples were then chemically and microbiologically analyzes. The contents of metals as Cu, Cd, Pb and Zn were determined by culometric method. On the basis of conducted analyzes it was proved that soil on the researched area was polluted by heavy metals. Mainly chromium contents in every sample was high what means that the tannery wastes occurs in the area of collecting samples. The investigation proved the influence of heavy metals on soil microflora. Various sorts of microorganisms have various tolerance on high metals concentration. The most resistant were ferruginous, nitrificative and denitrificative bacteria, the less resistant were meso- and psychrophilic bacteria and fungi.
Celem badań przedstawionych w artykule było zbadanie zawartości metali ciężkich w pobliżu zakładów garbarskich oraz określenie ich wpływu na mikroflorę gleby. W tym celu pobrano próbki gleby z terenu, który dawniej był ograniczony z jednej strony zabudowaniami zakładów przemysłowych (zakładów garbarsko-kuśnierskich, galwanizacyjnych i chemii gospodarczej), a z trzech pozostałych rzeką Wilgą i dwoma niewielkimi stawami, do których najprawdopodobniej odprowadzane były ścieki z tych zakładów. Pobrane próbki poddano analizie chemicznej oraz ilościowej i jakościowej analizie mikrobiologicznej. Zawartości metali takich jak Cu, Cd, Pb, Zn oznaczono metodą kulometryczną. Na podstawie przeprowadzonych analiz stwierdzono, że gleba na badanym terenie została zanieczyszczona metalami ciężkimi, szczególnie zawartość chromu we wszystkich próbkach była wysoka, co może wskazywać na obecność odpadów garbarskich w pobliżu miejsca pobrania próbek. Przeprowadzone badania udowodniły również wpływ metali ciężkich na mikroflorę gleby. Stwierdzono, że różne rodzaje mikroorganizmów posiadają różną tolerancję na wysokie stężenia metali. Najbardziej odporne okazały się bakterie żelaziste, nitryfikacyjne i denitryfikacyjne, najmniej odporne bakterie mezo- i psychrofilne oraz grzyby.
