Use of zeolite to neutralise nickel in a soil environment

Nickel is a heavy metal which is a stable soil pollutant which is difficult to remediate. An attempt to reduce its impact on the environment can be made by changing its solubility. The right level of hydrogen ions and the content of mineral and organic colloids are crucial in this regard. Therefore, methods to neutralise heavy metals in soil are sought. There are no reports in...

Resistance of aerobic microorganisms and soil enzyme response to soil contamination with Ekodiesel Ultra fuel

Mirosław Wyszkowski 1 Agata Borowik 2 Responsible editor: Robert Duran 3 Jadwiga Wyszkowska 4 Department of Environmental Chemistry, University of Warmia and Mazury in Olsztyn , Plac Łódzki 4, 10-727

The Role of Compost in Stabilizing the Microbiological and Biochemical Properties of Zinc-Stressed Soil

The progressive development of civilization and intensive industrialization has contributed to the global pollution of the natural environment by heavy metals, especially the soil. Degraded soils generally contain less organic matter, and thus, their homeostasis is more often disturbed, which in turn manifests in changes in biological and physicochemical properties of the soil...

Brown Algae and Basalt Meal in Maintaining the Activity of Arylsulfatase of Soil Polluted with Cadmium

This study analysed the effectiveness of innovative (basalt meal, brown algae extract) and conventional (barley straw) substances which hypothetically alleviate the inhibiting effect of Cd2+ on biochemical properties of soil, with particular regard to the activity of arylsulfatase. An analysis of their potential was carried out based on the activity of arylsulfatase and the...

Reaction of soil enzymes and spring barley to copper chloride and copper sulphate

Department of Microbiology, University of Warmia and Mazury , Plac Ło ́dzki 3, 10-727 Olsztyn , Poland 1 & Jadwiga Wyszkowska Study was carried out to compare the effect of the degree of contamination of soil

Bioaugmentation of Soil Contaminated with Azoxystrobin

The presence of fungicides in the natural environment, either resulting from deliberate actions or not, has become a serious threat to many ecosystems, including soil. This can be prevented by taking appropriate measures to clear the environment of organic contamination, including fungicides. Therefore, a study was conducted aimed at determining the effect of bioaugmentation of...

The Influence of Nitrogen on the Biological Properties of Soil Contaminated with Zinc

This study analyzed the relationship between nitrogen fertilization and the biological properties of soil contaminated with zinc. The influence of various concentrations of zinc and nitrogen on the microbiological and biochemical activity of soil was investigated. In a laboratory experiment, loamy sand with pHKCl 5.6 was contaminated with zinc (ZnCl2) and fertilized with urea as...

The effect of the Falcon 460 EC fungicide on soil microbial communities, enzyme activities and plant growth

0 Department of Microbiology, University of Warmia and Mazury in Olsztyn , Plac Łódzki 3, Olsztyn 10-727 , Poland 1 Jan Kucharski 2 Małgorzata Baćmaga 3 Jadwiga Wyszkowska Fungicides are considered

Biological activity of soil contaminated with cobalt, tin, and molybdenum

In this age of intensive industrialization and urbanization, mankind’s highest concern should be to analyze the effect of all metals accumulating in the environment, both those considered toxic and trace elements. With this aim in mind, a unique study was conducted to determine the potentially negative impact of Sn2+, Co2+, and Mo5+ in optimal and increased doses on soil...

Response of microorganisms and enzymes to soil contamination with a mixture of terbuthylazine, mesotrione, and S-metolachlor

The research objective has been to evaluate the effect, unexplored yet, of a mixture of three active ingredients of the herbicide Lumax 537.5 SE: terbuthylazine (T), mesotrione (M), and S-metolachlor (S) on counts of soil microorganisms, structure of microbial communities, activity of soil enzymes as well as the growth and development of maize. The research was based on a pot...

Response of microorganisms and enzymes to soil contamination with a mixture of pethoxamid terbuthylazine

Wyszkowska Introduction In the last several decades, an increase has been observed in the use of chemical plant protection products in agriculture. Because of such wide use of pesticides, their remains

Soil Dehydrogenases as an Indicator of Contamination of the Environment with Petroleum Products

The aim of the research was to compare the effects of various petroleum products, biodiesel, diesel oil, fuel oil and unleaded petrol on soil dehydrogenases, and to evaluate biostimulation with compost and urea in the restoration of homeostasis of the soil contaminated with these products. The obtained results allowed for defining the weight of dehydrogenases in monitoring of the...

Microbial and enzymatic activity of soil contaminated with azoxystrobin

The use of fungicides in crop protection still effectively eliminates fungal pathogens of plants. However, fungicides may dissipate to various elements of the environment and cause irreversible changes. Considering this problem, the aim of the presented study was to evaluate changes in soil biological activity in response to contamination with azoxystrobin. The study was carried...

Activity of Arylsulphatase in Soil Contaminated with Polycyclic Aromatic Hydrocarbons

Microbial and enzymatic activity of soil contaminated with a mixture of diflufenican + mesosulfuron-methyl + iodosulfuron-methyl-sodium

The aim of this study was to determine the effect of three active substances, diflufenican, mesosulfuron-methyl and iodosulfuron-methyl-sodium, applied in combination, on soil microbial counts, the structure of soil microbial communities, activity of soil enzymes and their resistance to the tested product, the biochemical indicator of soil fertility, and spring wheat yield.
