Fidel, Rivka B.; et al. (2017): Impact of Biochar Organic and Inorganic Carbon on Soil CO2 and N2O Emissions

Fidel, Rivka B.; Laird, David A.; Parkin, Timothy B. (2017): Impact of Biochar Organic and Inorganic Carbon on Soil CO2 and N2O Emissions. In: Journal of environmental quality. DOI: 10.2134/jeq2016.09.0369.

„Here we therefore aim to assess biochar organic and inorganic C pool impacts on CO₂ and N₂O emissions from soil amended with two untreated biochars, inorganic carbon (as Na₂CO₃), acid (HCl) and bicarbonate (NaHCO₃) extracts of the biochars, and acid and bicarbonate/acid-washed biochars during a 140-d soil incubation. We hypothesized that (i) both biochar labile organic carbon (LOC) and inorganic carbon (IC) pools contribute significantly to short-term ([lt]1 mo) CO₂ emissions from biochar-amended soil, (ii) biochars will influence the size of soil NH₄⁺ and NO₃⁻ pools, and (iii) changes in soil inorganic N pools will affect soil N₂O emissions.“
