“…The respiratory-activation quotient, which illustrates the biomass of dormant or active microorganisms, ranged from 0.17 to 0.49 (Figure 3). As stated by Eisentraeger et al [44], the respiratory-activation quotient value from 0.1 to 0.3 is low and indicates a substantial amount of biomass of dormant microorganisms, as well as slow bioremediation in the presence of potentially toxic substances in the soil. Hence the most desirable for the soil is a high basal respiration value.…”

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.

“…The respiratory activity coefficient quotient (QR) determined in the study, which illustrates the number of dormant or active microorganisms, ranged from 0.11 to 0.14 for the LS soil and from 0.11 to 0.22 for the C soil (Table 5). As reported by Eisentraeger et al (2000), a respiratory activity coefficient ranging from 0.1 to 0.3 is low and indicates a large amount of dormant microorganismal biomass as well as a low rate of bioremediation with potential toxic substances in the soil. From this point of view, a high BR value is most desirable for soil.…”

The study was carried out with cavitated charcoal that were introduced into loamy sand and clay at rates of 1.76%, 3.5%, 7.0%, and 14.0%. The highest introduction rate of the material (14.0%) increased the content of total carbon (CTot) by 197% in the loamy sand and by 19% in the clay compared to that in the control treatments. The application of cavitated charcoal did not significantly change the total content of heavy metals. Regardless of the element and the soil used, the application of cavitated charcoal reduced the content of the CaCl2-extracted forms of heavy metals. Following the application of cavitated charcoal, the loamy sand soil presented an even lower content of the most mobile forms of the studied elements. It should also be noted that regardless of the soil texture, mobile forms of the elements decreased with the increased cavitated charcoal rate. The respiratory activity values of the soils into which cavitated charcoal was introduced were low, which indicates a large number of dormant microorganisms. Additionally, the results of dehydrogenase and urease activity indicated the low metabolic activity of the microbial population in the soils, especially with the relatively high rates (7.0% and 14.0%) of cavitated charcoal. However, the cavitated charcoal used in the study showed a significant, positive effect on the amount of biomass Sorghum saccharatum (L.), and its application significantly reduced the heavy metal content in the biomass of Sorghum saccharatum (

“…the exponential slope in the respiration curve as defined in ISO 17155 [24]) started later in the contaminated soil samples at the beginning of incubation. It has been reported that prolonged lag-times may indicate a toxic effect of chemicals on the microbial communities [28][29][30]. The lag-time of microbial respiration (defined as time from substrate addition to start of exponential growth according to ISO 17155 [24]) may also reflect the quality of the previously available carbon source [31].…”
