Biodegradation measurements confirm the predictive value of the O:C-ratio for biochar recalcitrance.
J. Plant Nutr. Soil Sci. 177, 633-637 (2014)
Suitable predictors of degradability are sought to support the identification of biochars with large potential to increase C sequestration in soils. We determined the biodegradation of 9 chars from hydrothermal carbonization and pyrolysis in two agricultural soils. The 200- and 115-day degradation correlated strongly with the O:C- and slightly with the H:C-atomic ratio of 9 and 14 biochars, respectively. Highest temperature treatment and ash content did not show similar correlations.
