2017-2-2 · Biochar has been widely proposed to be valuable in the sequestering of carbon (C) in soil due to its chemical and biological recalcitrance. However whether biochar could cause soil positive priming effects (PEs) which offset the effects of soil organic C sequestration has raised a very controversial issue and debate recently. Changed soil properties like microbial community composition
Moreover the biochar amendments induced obvious shifts of the bacterial community towards low C turnover bacteria taxa (e.g. Actinobacteria and Deltaproteobacteria) and the bacteria taxa responsible for stabilizing soil aggregates (e.g. Actinobacteria and Acidobacteria) which also accounted for the negative priming effect.

2018-11-6 · The present study assesses the stability of biochar its effect on original soil organic matter (SOM) decomposition and the interactions with plant roots over a 3-year period in a short rotation coppice plantation in Northern Italy. Biochar produced from gasification of maize silage (δ13C of biochar ≈ − 13.8‰) was applied into the soil of the plantation (δ13C of SOM ≈ −23.5‰).
2015-1-1 · Priming effect. The priming effect (PE) of native SOC induced by biochar was calculated as follows (Kuzyakov and Bol 2006) (2) PE = C B SOC − C SOC Where C B SOC is the amount (mg kg −1 soil) of CO 2 –C evolved from soil in the presence of biochar and C SOC is the amount (mg kg −1 soil) of CO 2 –C evolved from soil without biochar (i.e. control soil). The primed native SOC mineralisation
Biochar is considered as an attractive tool for long-term carbon (C) storage in soil. However there is limited knowledge about the effect of labile organic matter (LOM) on biochar-C mineralization in soil or the vice versa. An incubation experiment (20 °C) was conducted for 120 days to quantify the

2014-8-7 · Therefore the root-induced priming effect on biochar decomposition could be due to a shift towards a more efficient biochar-decomposing microbial community. The different plant species and rhizodeposits could explain why in United Kingdom the decomposition rate was higher than in Italy notwithstanding the lower temperature recorded in the latter site.
The priming effect (PE) induced by biochar provides a basis for evaluating its carbon (C) sequestration potential in soils.
Biochar has the potential to store carbon (C) in soils on a millennial time scale and hence it is proposed as a tool to aid in the mitigation of climate change. However the presence of biochar in soil can induce either a positive or negative priming effect on native soil C or the converse which may either reduce or enhance the C storage potential of biochar.
Moreover the biochar amendments induced obvious shifts of the bacterial community towards low C turnover bacteria taxa (e.g. Actinobacteria and Deltaproteobacteria) and the bacteria taxa responsible for stabilizing soil aggregates (e.g. Actinobacteria and Acidobacteria) which also accounted for the negative priming effect.

The priming effect is the increase in soil organic matter (SOM) decomposition rate after the addition of fresh organic matter or other compounds to soil. The implication is that is biochar if addition leads to the loss of native SOM it negates the carbon benefit of adding biochar to soil. However there could also be potential benefits of
