Wheat straw and its biochar have contrasting effects on inorganic N retention and N2O production in a cultivated black chernozem

Abstract

A laboratory incubation experiment was conducted to investigate the effects of direct incorporation of either wheat straw or its biochar into a cultivated Chernozem on gross N transformations calculated by the 15N pool dilution technique and nitrous oxide (N2O) production rates. Incorporation of wheat straw stimulated gross NH 4 + (ammonium) and NO 3 − (nitrate) immobilization rates by 302 and 95.2 %, respectively, suppressed gross nitrification rates by 32.2 %, and increased N2O production by 37.7 %. In contrast, the addition of a biochar produced from the wheat straw did not influence any of the above N cycling processes. Therefore, application of biochar could be a possible management strategy for long-term C sequestration (through soil storage of stable C contained in the biochar) in soils without increasing N2O production rates, but could not effectively immobilize NO 3 − in the soil.

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.
