Biochar addition to agricultural soil increased CH4 uptake and water holding capacity – Results from a short-term pilot field study
Abstract
Biochar addition to agricultural soil has been suggested to mitigate climate change through increased biogenic carbon storage and reduction of greenhouse gas emissions. We measured the fluxes of N₂O, CO₂, and CH₄ after adding 9tha⁻¹ biochar on an agricultural soil in Southern Finland in May 2009. We conducted these measurements twice a week for 1.5 months, between sowing and canopy closure, to capture the period of highest N₂O emissions, where the potential for mitigation would also be highest. Biochar addition increased CH₄ uptake (96% increase in the average cumulative CH₄ uptake), but no statistically significant differences were observed in the CO₂ and N₂O emissions between the biochar amended and control plots. Added biochar increased soil water holding capacity by 11%. Further studies are needed to clarify whether this may help balance fluctuations in water availability to plants in the future climate with more frequent drought periods.

“In a field study with Birch (Betula spp.) biochar incorporated into a silt loam soil in Finland, biochar addition increased water-holding capacity by 11% compared to the unamended control (Karhu et al., 2011).”

“However, the effects of biochar addition on CH 4 and N 2 O were inconsistent and have shown variability with crop and soil types, site condition, and the origin of the biochar (Karhu et al., 2011;Kimetu and Lehmann, 2010;Lehmann et al., 2011b;Spokas et al., 2009;Zimmerman et al., 2011).”

In the citing paper
“In addition to the beneficial effects of drawing CO 2 from the atmosphere, biochar application was reported to decrease emissions of CH 4 and N 2 O from soils (Cavigelli and Robertson, 2001;Karhu et al., 2011;Liu et al., 2011;Rogovska et al., 2011;Rondon et al., 2006Rondon et al., , 2005;;Zhang et al., 2012a).”

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.
