Abstract

Willow coppice, energy maize and M iscanthus were evaluated regarding their soil‐derived trace gas emission potential involving a nonfertilized and a crop‐adapted slow‐release nitrogen (N) fertilizer scheme. The N application rate was 80 kg N ha−1 yr−1 for the perennial crops and 240 kg N ha−1 yr−1 for the annual maize. A replicated field experiment was conducted with 1‐year measurements of soil fluxes of CH4, CO2 and N 2 O in weekly intervals using static chambers. The measurements revealed a clear seasonal trend in soil CO2 emissions, with highest emissions being found for the N‐fertilized M iscanthus plots (annual mean: 50 mg C m−² h−1). Significant differences between the cropping systems were found in soil N 2 O emissions due to their dependency on amount and timing of N fertilization. N‐fertilized maize plots had highest N 2 O emissions by far, which accumulated to 3.6 kg N 2 O ha−1 yr−1. The contribution of CH4 fluxes to the total soil greenhouse gas subsumption was very small compared with N 2 O and CO2. CH4 fluxes were mostly negative indicating that the investigated soils mainly acted as weak sinks for atmospheric CH4. To identify the system providing the best ratio of yield to soil N 2 O emissions, a subsumption relative to biomass yields was calculated. N‐fertilized maize caused the highest soil N 2 O emissions relative to dry matter yields. Moreover, unfertilized maize had higher relative soil N 2 O emissions than unfertilized M iscanthus and willow. These results favour perennial crops for bioenergy production, as they are able to provide high yields with low N 2 O emissions in the field.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some papers cover other greenhouse gases, such as carbon dioxide and/or methane.

    “Some papers cover other GHGs, like CO2 and/or methane [48, 49, 53–55, 57].”
  • Experimental evidence for directly measured greenhouse gas emissions was found in 12 papers from eight different experiments, mainly on nitrous oxide from Miscanthus, switchgrass, short-rotation coppice willow and/or short-rotation coppice poplar, mainly following arable but some also after grassland.

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.
