Biochar and soil biota by Natalia Ladygina, Francois Rineau

By Natalia Ladygina, Francois Rineau

Biochar, a biomass that's burned at a truly hot temperature within the absence of oxygen, has lately turn into an enticing topic of research. Biochar is very strong and doesn't degrade; it possesses actual homes that help in retention of nutrition within the soil. using biochar will certainly have an important effect not just on soil foodstuff but in addition on soil organism groups and their functions.

2000, Brodowski et al. 2006) which could slow degradation by limiting access by oxygen or microbial enzymes. Soil OM, being a more labile C source than pyrogenic C, could stimulate the production of microbial exoenzymes, leading to the co-metabolism of BC. This accelerated mineralization of a refractory OM component when stimulated by the presence of a labile C source has been termed ‘positive priming’ (Kuzyakov et al. 2000). Making matters more complicated, the presence of biochar could either impede or accelerate the mineralization of soil OM.
