Opis:: The aim of this study was to analyse the influence of municipal sewage sludge on selected microbiological parameters in the rhizosphere of lawn grass mixtures. Four experiments on the lawns along the main roads of Bialystok were founded. The factors in the experiment were three doses of sewage sludge (0 – control; 7.5 and 15 kg·m^-2) and two grass mixtures (Eko and Roadside). The studied parameters were monitored twice during 2011 vegetation season by determining the total number of soil microorganisms, the total number of Gram-negative bacteria, the number of bacteria of Pseudomonas fluorescens species, the number of amylolytic and proteolytic bacteria. Sewage sludge amended to soil resulted in a change of physical-chemical properties of soil. The sewage sludge application to soil influenced significantly the number of proteolytic and Gram-negative bacteria.

Opis:: The aim of the study was to present the dynamics of changes in the number of selected microorganisms in the rhizosphere zone of grasses two years after the application of sewage sludge. The study was conducted on four specially prepared research plots along the main roads in Bialystok. Three doses of sewage sludge were applied: 0 (control), 7.5 and 15 kg/m². Then the plots were seeded with two mixtures of lawn grasses: Eko and Roadside. Samples of roots with soil were collected three times during the vegetation period of 2012 (April, July and October) and assayed for the total number of bacteria, the number of Gram-negative bacteria, the number of Pseudomonas fluorescens, the number of amylolytic and proteolytic bacteria. Microbiological tests of the rhizosphere showed seasonal variations of all investigated microbiological parameters. The greatest average of the total number of bacteria, Gram-negative bacteria and proteolytic bacteria was observed on the plots in April, amylolytic bacteria in July while in the case of Pseudomonas fluorescens was observed on the plots in October. The time of measurement had the biggest impact on the number of microorganisms. An increased number of microorganisms was observed on all plots in April. Whereas, the fertilization with sewage sludge and grass mixtures did not affect the microbiological parameters.

Opis:: The aim of this work was to investigate the influence of fresh and thermally treated sewage sludge on the amylolytical activity of the urban soils. Two experimental areas on the lawns along the main roads of Bialystok were prepared in 2011 and 2015. The factors taken into account in the experiment involved: the type of sewage sludge (mechanically dewatered – SS and thermally dried “Granbial” – G), three doses of sewage sludge (0 – control; 14.5 and 29 t DM/ha) and two grass mixtures (Eko and Roadside). The number of amylolytic bacteria in grass mixtures and rhizosphere and amylase activity in soil were monitored twice during 2011 and 2012 vegetation season (in July and October). The main properties of soil (soil pH, granulometric composition, total organic carbon – TOC, available phosphorus and total nitrogen content) after the application of organic substrates were also analysed. Addition of the dewatered sewage sludge to soil resulted in an increase in the number of amylolytic bacteria (from 7.4 to 18.8 ∙10⁶ cfu/g DM) in July, while in the soil treatment with thermally dried sludge, the increased number of the bacteria (from 11.03 to 44.68 ∙10⁶ cfu/g DM) was observed in October. The amylases activity in the soil treated with SS exhibited the highest average value in July (2.11 mg Glc/g DM ∙24 h), while in the soil treated with “Granbial”, it was stable in studied period (from 1.65 to 2.18 mg Glc/g DM ∙24 h).
