Biochar carbon stability in four contrasting soils

Summary There is a limited understanding of the effects of soil properties on biochar carbon ( C ) stability. This knowledge is essential to evaluate the capacity of biochar for long‐term soil C sequestration fully. In this study two biochars, produced by slow pyrolysis at 450 or 550°C from a δ 13 C ‐depleted (−36.4‰) Eucalyptus saligna Sm. woody material, were incubated in four soils ( I nceptisol, E ntisol, O xisol and V ertisol) of...
