“…Despite the reliance of AOB populations on NH 4 -N, there was no correlation between amoA and NH 4 -N which indicates that additional factors, currently unknown, must have played a role in regulating amoA abundances. Abundances of amoA were seen to decrease after the second month, which is similar to results published by Anderson et al (2011) that demonstrated decreases in the abundance of Nitrosomonadaceae in soils treated with ryegrassderived biochar. It should be noted that control soils exhibited a similar pattern, indicating that the study conditions may have factored in the exhibited patterns of amoA.…”

“…They reported that while microbial biomass did not vary between biochar treatments, microbial PLFA patterns were significantly altered. Using terminal restriction fragment length polymorphism (T-RFLP) analysis, Anderson et al (2011) reported shifts in microbial community structure in the presence of a pinederived (Pinus radiata) biochar. These authors also noted shifts in the relative abundances of organisms involved in soil nitrogen cycling; in particular, increases were reported in organisms shown to be involved in nitrogen fixation and denitrification, and decreases in organisms shown to be involved in nitrification (Anderson et al, 2011).…”

“…In addition to the report by Anderson et al (2011), there have been a number of papers discussing the topic of N-cycling, in particular nitrous oxide emissions, and the effect of biochar on these processes . Ball et al (2010) demonstrated the effects of charcoal, produced by wildfire in coniferous-dominated forests, on increased soil nitrification rates and nitrifier abundances.…”

a b s t r a c tIt has been demonstrated that soil amended with biochar, designed specifically for use as a soil conditioner, results in changes to the microbial populations that reside therein. These changes have been reflected in studies measuring variations in microbial activity, biomass, and community structure. Despite these studies, very few experiments have been performed examining microbial genes involved in nutrient cycling processes. Given the paucity of research in this area, we designed a 6 month study in a Portneuf subsoil treated with three levels (1%, 2%, and 10% w/w ratio) of a biochar pyrolyzed from switchgrass (Panicum virgatum) at 350 • C and steam activated at 800 • C to measure the abundances of five genes involved in N cycling. Gene abundances were measured using qPCR, with relative abundances of these genes calculated based on measurement of the 16S rRNA gene. At the end of the 6 month study, all measured genes showed significantly greater abundances in biochar amended treatments as compared to the control. In soil amended with 10% biochar, genes involved in nitrogen fixation (nifH), and denitrification (nirS), showed significantly increased relative abundances. Lastly, gene abundances and relative abundances correlated with soil characteristics, in particular NO 3 -N, % N and % C. These results confirm that activated switchgrass-derived biochar, designed for use as a soil conditioner, has an impact on the treated soils microbial communities. We therefore suggest that future use of biochar as a soil management practice should take into account not only changes to the soil's physiochemical properties, but its biological properties as well.Published by Elsevier B.V.

“…3A, and Table 1). Previous studies reported an increase in bacterial abundance and altered microbial communities after BC addition under controlled laboratory conditions, which was attributed to the physic-chemical properties of BC (e.g., sorption, pH, chemical properties, habitats) (Anderson et al, 2011;Hale et al, 2015;Pietikäinen et al, 2000). However, such short-term positive effects of the physico-chemical properties of BC on microorganisms under controlled laboratory conditions were not as notable in our long-term field study.…”

“…They are sensitive indicators to monitor biochemical processes in soil [47,50]. Most studies published so far recognised the importance of soil microorganisms in the conversion and storage of carbon, as well as in the maximisation of the potential benefits of biochar applied to the soil to stimulate its biological activity and increase the retention of nutrients introduced with fertilisers [4,24]. However, these studies lack information on the biochar's effect on soil respiration activity and, above all, nitrifying bacteria activity, which are one of the most sensitive indicators of changes in the soil environment.…”

treatment with mineral fertilisation applied (MF), by 59 and 77%, respectively. The significantly highest basal respiration value was determined in soil with 5 t DM ha −1 biochar. The application of poultry litter had significant effect on nitrifying bacteria activity (increase by 50%). Poultry litter biochar added to the soil in both doses contributed to an increase in nitrifying bacteria activity by 36 and 34%, respectively compared to MF treatment. Biochar had more adverse effect on soil microbial biomass and nitrifying bacteria activity than non-converted poultry litter, but it had significant effect on soil respiration activity. AbstractThe application of organic materials, such as poultry litter or poultry litter biochar, may lead to major changes in the structural and functional diversity of microbial populations. The understanding of the relationship between microorganisms and environment is crucial to assess the effect of organic materials on soil. Therefore, the objective was to evaluate the influence of the addition of poultry litter (5 t DM ha −1 ) and poultry litter biochar in doses of 2.25 t and 5 t DM ha −1 on soil respiration activity, microbial biomass, and nitrifying bacteria activity. In soils with poultry litter biochar added in 2.25 t and 5 t DM ha −1 doses, microbial biomass was significantly higher than in * M. Mierzwa-Hersztek
