Analysis of total organic carbon in soil-biochar systems
August 20-25, 2017
Amending agricultural soils with biochar can contribute to negative carbon strategies when the resistance to oxidation of soil carbon is improved (avoided CO2 emission) and plant growth is promoted (increased CO2 fixation). The environmental stability and sequestering capacity of biochar is dependent on the chemical form of carbon and its physical location in the carbonaceous matrix. The addition of biochar in soil increases noticeably the stable carbon pool, while the effect on labile carbon, including polyaromatic structures, is less marked.1 The fertilizing action can be lost if biochar is removed from the cultivated area due to physical processes (vertical transport, lateral export, slacking). Assessing the fate of carbon in the soil requires the use of suitable analytical methods that should be validated for the presence of biochar.
