Application of biochar to soil and N 2 O emissions: potential effects of blending fast‐pyrolysis biochar with anaerobically digested slurry

Abstract

Soil applications of recalcitrant biochar offer the possibility of mitigating climate change effects through long‐term carbon sequestration and potentially also by reducing emissions of the potent greenhouse gas nitrous oxide (N 2 O). This laboratory study examined the effect of combining a fast‐pyrolysis biochar at small (1% by mass) and large (3%) concentrations with anaerobically digested slurry on soil N 2 O and carbon dioxide (CO 2 ) emissions over a period of 55 days. The results showed that fast‐pyrolysis biochar applied on its own increased N 2 O emissions from soil. However, when biochar was applied together with slurry, the larger biochar concentration decreased N 2 O emissions by 47%, relative to those from the slurry treatment with the smaller biochar concentration. Reduced N 2 O emissions coincided with enhanced soil microbial activity and immobilization of nitrogen. A combined application of biochar and anaerobic digested slurry could therefore be beneficial for cropping systems in terms of soil nitrogen retention while concurrently mitigating N 2 O fluxes and sequestering carbon in soil.

  • Biochar addition decreases total N2O emission from soils treated with N sources such as manure, urea, and compost.

    “Biochar addition has often been shown to decrease total N2O emission from soils treated with N sources such as manure, urea, and compost (Bruun et al. 2011;Singh et al. 2010;Spokas et al. 2009).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
