“…In our study, the only weak negative correlation was observed between the number of fungi and total Ni concentrations. Similar to our research, Lenart-Boroń and Wolny-Koładka [34] did not detect any effects of elevated concentrations of some heavy metals, mainly Zn and Pb, on the numbers of some microbial groups (mesophilic bacteria, Azotobacter, actinomycetes, fungi) in soils. Niemeyer et al [10] observed a negative correlation between soil respiration and total concentrations of Pb, but not with Ni; in addition, ammonifiers correlated negatively with Cu, Fe, Mn, Zn, Cd, Cr, Pb, Ni.…”

Soil chemical properties and total heavy metal concentrations (As, Cd, Cr, Cu, Ni, Pb, Zn, Fe and Mn) and their relationships with some soil microbiological characteristics (such as soil respiration and numbers of specific groups of microorganisms) were evaluated in agricultural soils in southern Serbia. In 42% of samples, slightly elevated concentrations of As, Ni and/or Pb were detected, with the highest values of 43.4, 64.4 and 184.1 mg/kg, respectively. No significant differences were observed in soil microbiological characteristics between soil samples with elevated heavy metals and heavy metals below the maximum allowed concentrations (MAC). There was no negative correlation between any of the heavy metals and any microbiological characteristics, except the total number of fungi and the concentration of Ni (r=-394). Positive correlations between most of the heavy metals and the number of Azotobacter were obtained. Correlation analysis and stepwise multiple regression analyses indicated that the chemical properties of the soil are the factors that affected the number of microorganisms the most. The content of CaCO 3 significantly contributed to variations in soil respiration (39%), the total number of microorganisms was affected the most by humus (53%), oligonitrophiles by the total N content (49%), while the numbers of actinomycetes and fungi were affected by the pH (48% and 58% of the variation).

“…Compared with chemical and physical properties, biological properties can constitute not only early but also more sensitive environmental indicators, providing information on the presence of potentially toxic substances such as trace elements [21]. As reported by Lenart-Boro n and Wolny-Koładka [22], microorganisms are the first group that undergo any direct and indirect effects of heavy metals in the soil environment, and adverse effects of metals on soil microorganisms may cause lessening of microbial diversity, reduced soil respiration, and decreased decomposition of organic matter, as well as reduction of the activities of some soil enzymes. However, despite the high importance of biological properties in the overall assessment of the soil quality, reports on the effect of sewage sludge biochar on the soil biological properties and ecotoxicity are few in quantity [7,23,24].…”

“…The soil microbial diversity has a significant impact on the integral functionality of soil, which in turn is fundamental for sustainable management of the natural environment [16,22,25]. The existing publications indicate a very wide variation in the chemical composition of sewage sludge biochars and their impact on the soil environment, which is not fully understood [2,3,5,12].…”

Production of biochar from sewage sludge may be a promising solution for sewage sludge management and improvement of soil properties, including carbon dioxide sequestration. The aim of the present study was to compare the effects of biochars derived from different sewage sludges on soil physicochemical and biological properties, ecotoxicity, and plant yield. Three biochars (produced at a temperature of 300 °C) were applied into sandy acid soil in doses of 0.5, 1, and 2% (w/w). Depending on the type and dose, the application of sewage sludge biochars into the soil caused diverse effects on the parameters of soil biological activity (microbial biomass [Cmic], soil respiration, and value of metabolic quotient). No correlation between the applied dose of biochars and inhibition of Vibrio fischeri luminescence was observed. The factor with a stronger impact on the activity of V. fischeri was the type of biochar. The use of the OSTRACODTOXKIT F test (MicroBioTests) showed that the addition of sewage sludge biochar (regardless of its dose) reduced the soil toxicity to Heterocypris incongruens compared with the control soil. A significant increase of Poa pratensis L. biomass was obtained in soils with 1 and 2% additions of each of the biochars. The addition of biochars in doses of 1 and 2% to the soil had greater effect on the content of mobile forms of Cu, Pb, and Cd than the 0.5% dose compared with the control.

“…Quantitative and qualitative changes in microbial populations have a significant impact on soil functional integrity, and soil microbial diversity is of fundamental importance for sustainable environmental management. Soil microorganisms are key indicators of soil quality due to their participation in many biochemical processes, essential for the environment and ecological functions of the soil [1][2][3][4][5]. The addition of organic matter to the soil may lead to significant changes in the structural and functional diversity of microbial population, and thus changes in the intensity of microbial degradation of organic connections [6,7].…”

Biochar improves soil physical, chemical and biological properties. However, there is a very limited number of studies comparing the effect of various doses of biochar and wheat straw with nutrients on microbiocenotic composition of soil and their connection with selected biochemical and chemical parameters of soil. The aim of this study was to determine the effect of the addition to the soil of wheat straw (WS) and wheat straw biochar (WSB) (300 °C) at 0.2%, 0.5%, 1%, and 2% doses and the addition of nutrients (MF) on microbial community composition (bacteria, fungi, actinobacteria, Azotobacter spp., ammonifiers, nitrifiers, denitrifiers, C. pasteurianum), dehydrogenase activity index, carbon and nitrogen fractions contents and the content of water soluble Cu, Cd, Zn, and Pb. It was demonstrated that coapplication of WS and WSB with MF at 1% and 2% doses increased carbon and nitrogen contents in soil and, in particular, their water soluble fractions (DOC and DON). The synergistic effect of biochar and MF contributed to the increase in the population of soil microorganisms. Dehydrogenase activity index in treatments with the addition of WS, WSB and MF was 1.6-4 times higher compared to the control. The content of heavy metals significantly (p ≤ 0.05) affected dehydrogenase activity and the number of nitrifiers and ammonifiers. It was demonstrated that the content of C and N measured for soil microbial biomass in treatments amended with biochar and MF was much greater than in control treatment and MF. However, our studies suggest that the microorganisms' response to the addition of biochar with nutrients increased the number and intensified the activity of soil microorganisms.
