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‰).
When root growth was excluded only 7 and 3 of the biochar carbon added was decomposed after 245 and 164 days in Italy and United Kingdom sites respectively. In the presence of roots this percentage was increased to 9 and 8 suggesting a small positive priming effect of roots on biochar
2018-9-5 · The negative priming effect of biochar on the mineralization of SOC was mainly observed after 15 days of incubation and increased with incubation time. The negative effects of BB and RH were significantly stronger than that of PS at the 5 application ratio. This was mainly due to the less pores and smaller specific surface area of PS which

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.
