Opis:: The study has been made to determine the effect of soil contamination with a new generation herbicide on the abundance and diversity of microorganisms, activity of soil enzymes and their tolerance to the herbicide Successor T 550 SE. Herbicide disturbed the biological balance of soil as expressed by the numbers and diversity of microorganisms and enzymatic activity. The recommended dose of herbicide significantly stimulated the growth of total oligotrophic and organotrophic bacteria as well as actinomycetes, depressed the activity of fungi and had no effect on oligotrophic sporulating bacteria and Azotobacter.

Opis:: The aim of this study was to determine the effect of carfentrazone-ethyl (CE) doses of 0.265, 5.280, 10.560, 21.180, 42.240 μg kg-1 soil DM on fungi, Acnomycetes, organotrophic bacteria, total oligotrophic bacteria and spore-forming oligotrophic bacteria, and on the activity of dehydrogenases, catalase, urease, alkaline phosphatase, acid phosphatase, arylsulfatase and β-glucosidase. Carfentrazone-ethyl had a stimulating effect on total oligotrophic bacteria and organotrophic bacteria, but it inhibited the growth of Azotobacter, fungi, spore-forming oligotrophic bacteria and Actinomycetes. The analyzed substance modified the structure of soil microbial communities, and it induced the most profound changes in fungi. The highest values of the colony development (CD) index and the eco-physiological (EP) index were observed in organotrophic bacteria. The optimal dose of carfentrazone-ethyl stimulated the activity of dehydrogenases, catalase, urease, alkaline phosphatase, acid phosphatase and β-glucosidase, but it had no effect on arylsulfatase. The highest doses of the analyzed substance inhibited the activity of dehydrogenases (reduction from 11.835 to 11.381 μmol TPF), urease (reduction from 0.545 to 0.500 mmol N-NH4) and arylosulfatase (reduction from 0.210 to 0.168 mmol PNP). Dehydrogenases were most resistant to CE, whereas acid phosphatase and arylsulfatase were least resistant to the analyzed compound.
W pracy określono wpływ karfentrazonu etylu zaaplikowanego w dawkach 0,265, 5,280, 10,560, 21,180, 42,2 40 μg kg-1s.m. gleby na grzyby, promieniowce, bakterie organotroficzne, oligotroficzne ogółem i oligotroficzne przetrwalnikujące oraz aktywność dehydrogenaz, katalazy, ureazy, fosfatazy alkalicznej, fosfatazy kwaśnej, arylosulfatazy i β-glukozydazy. W wyniku badań stwierdzono stymulujące działanie karfentrazonu etylu na bakterie oligotroficzne ogółem i bakterie organotrofi czne, natomiast inhibicyjne na Azotobacter, grzyby, bakterie oligotroficzne przetrwalnikujące oraz promieniowce. Preparat ten zmieniał strukturę zespołu drobnoustrojów. Największe zmiany wywoływał u grzybów. Najwyższe wartości wskaźników rozwoju kolonii (CD) i ekofi zjologicznej różnorodności (EP) odnotowano u bakterii organotroficznych. Karfentrazon etylu w dawce optymalnej zwiększał aktywność dehydrogenaz katalazy, ureazy, fosfatazy alkalicznej, fosfatazy kwaśnej i β-glukozydazy, a nie oddziaływał na arylosulfatazę, natomiast najwyższe dawki zmniejszały aktywność dehydrogenaz (obniżenie z 11,835 do 11,381 μmol TPF), ureazy (obniżenie z 0,545 do 0,500 mmol N-NH4) i arylosulfatazy (obniżenie z 0,210 do 0,168 mmol PNP). Najbardziej opornymi enzymami na działanie KE okazały się dehydrogenazy, a najmniej fosfataza kwaśna i arylosulfataza.

Opis:: Zinc is an essential element for all living organisms, but overexposure to this element can have strongly toxic effects. A pot experiment was carried out to evaluate the influence of different zinc concentrations (0, 100, 300, 600, 1200, 2400, 4800 mg Zn2+ kg-1 of soil) on the soil biological activity by analyzing changes in soil stability over time and by determining the resistance (RS) of microorganisms and soil enzyme activity. The influence of Zn2+ on the growth and development of oat and white mustard was evaluated. Overexposure to zinc inhibited the growth of soil microorganisms, the activity of soil enzymes, and the growth and development of plants. Excessive zinc doses cause lower microbial biodiversity and enzyme activity. Bacteria of the genus Azotobacter were most sensitive and spore-forming oligotrophic bacteria were least sensitive to excessive zinc doses. β-glucosidase was most resistant and arylsulfatase was least resistant to the analyzed element. The resistance of the tested microorganisms and enzymes decreased with an increase in zinc accumulation in the soil environment. White mustard was more sensitive to zinc contamination than oat and zinc doses of 2400 and 4800 mg Zn2+ kg-1 led to the death of white mustard plants. The results of this study indicate that soil contamination with zinc poses a threat for living organisms. In areas with a higher risk of zinc deposition, the content of this element in soils should be monitored more frequently than prescribed by environmental protection regulations.
