“…An inconsistent effect of biochar on microbial communities suggests that biochar effects are likely biochar-and soil-specific, related to the rate applied to soil, and/or require greater statistical replication. For example, others have found no effect of biochar on microbial communities when the biochar does not affect the pH of an already neutral or alkaline soil (Meynet et al, 2012), or when biochar does not provide enough labile C substrates (high pyrolysis temperature) or nitrogen (hardwood biochar) to stimulate microorganisms (Bruun et al, 2011;Luo et al, 2011). Biochar in the current study did not affect soil pH (Lentz and Ippolito, 2012) and did not contain appreciable quantities of N (Table 1).…”

“…The multicomponent character of biochar, with a labile fraction that mineralizes as fast as ordinary soil organic matter, is well-documented (Hilscher et al, 2009;Smith et al, 2010;Bruun et al, 2011;Calvelo Pereira et al, 2011;Zimmerman et al, 2011;Rittl et al, 2015b). This labile fraction is mainly residual cellulose (O-alkyl and di-O-Alkyl groups; see figure 4) from incomplete carbonization (Hilscher et al, 2009;Bruun et al, 2011) and alkyl groups (Hilscher et al, 2009;Rittl et al, 2015b), that correspond to the transition chars in the multi-phase model.…”

However, amorphous and composite chars, which are also part of the aromatic structure, are prone to oxidation in the first days of incubation (Hilscher et al, 2009).…”

“…But in general, despite the fast decomposition of these labile fractions, the net result is C sequestration (Hilscher et al, 2009;Smith et al, 2010;Bruun et al, 2011;Zimmerman et al, 2011;Rittl et al, 2015b), probably due to the expected long residence time of the turbostratic chars, even when positive priming occurs in the mineralization of native soil organic matter (Jones et al, 2011). Besides, the interaction between soil type and biochar structure and composition, allows to "design" the biochar (Novak et al, 2014) even for C sequestration aims (Steinbeiss et al, 2009).…”

Biochar (carbonized biomass for agricultural use) has been used worldwide as soil amendment and is a technology of particular interest for Brazil, since its "inspiration" is from the historical Terra Preta de Índios (Amazon Dark Earth), and also because Brazil is the world's largest charcoal producer, generating enormous residue quantities in form of fine charcoal and due to the availability of different residual biomasses, mainly from agroindustry (e.g., sugar-cane bagasse; wood and paper-mill wastes; residues from biofuel industries; sewage sludge etc), that can be used for biochar production, making Brazil a key actor in the international scenario in terms of biochar research and utilization). In the last decade, numerous studies on biochar have been carried out and now a vast literature, and excellent reviews, are available. The objective of this paper is therefore to deliver a critical review with some highlights on biochar research, rather than an exhaustive bibliographic review. To this end, some key points considered critical and relevant were selected and the pertinent literature "condensed", with a view to guide future research, rather than analyze trends of the past.

“…However, the results of studies on the microbial response to the presence of biochar in the soil are often ambiguous and inconsistent. Bruun et al [7] and Luo et al [37] proved that thermally unconverted poultry litter and poultry litter biochar added to the soil causes an increase in microbial biomass. The authors believed that this results from the introduction into the soil of labile carbon compounds with these materials.…”

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
