Soil carbon, soil nitrate, and soil emissions of nitrous oxide during cultivation of energy crops

Abstract

Carbon (C) sequestration and soil emissions of nitrous oxide (N₂O) affect the carbon dioxide (CO₂) advantage of energy crops. A long-term study has been performed to evaluate the environmental effects of energy crop cultivation on the loamy sand soil of the drier northeast region of Germany. The experimental field, established in 1994, consisted of columns (0.25 ha each) cultivated with short rotation coppice (SRC: Salix and Populus) and columns cultivated with annual crops. The columns were subdivided into four blocks, with each receiving different fertilization treatments. The soil C content was measured annually from 1994 until 1997, and then in 2006. Soil N₂O levels were measured several times per week from 1999 to 2007. Water-filled pore space (WFPS) and soil nitrate measurements have been performed weekly since 2003. Increased C stocks were found in SRC columns, and C loss was observed in blocks with annual crops. The soil from fertilized blocks had higher levels of C than the soil from non-fertilized blocks. SRC cropping systems on dry, loamy sand soils are advantageous relative to annual cropping systems because of higher C sequestration, lower fertilized-induced N₂O emissions, and reduced background N₂O emissions in these soils. SRC cropping systems on dry, loamy sand soils have a CO₂ advantage (approximately 4 Mg CO₂ ha⁻¹ year⁻¹) relative to annual cropping systems.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Emissions of N2O from dry, well-aerated soils, regardless of the management practice applied, are negligible compared with N2O emissions from poorly drained and fine-textured soils in high rainfall areas.

    “Emissions of N 2 O from dry, well-aerated soils, regardless of the management practice applied, are negligible compared with N 2 O emissions from poorly drained and fine-textured soils in high rainfall areas (Rochette, 2008;Hellebrand et al., 2010).”
  • 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.

    “Experimental evidence for directly measured GHG emissions was found in 12 papers from eight different experiments, mainly on nitrous oxide (N2O) from Miscanthus [48–51], switchgrass [52, 53], SRC willow and/or SRC poplar, mainly following arable [48, 49, 54] but some also after grassland [55, 56].”
  • An increased annual soil organic carbon storage change was observed in response to fertilisation, particularly in poplar stands.

    “An increased annual SOC storage change was observed in response to fertilisation, particularly in poplar stands [54].”

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.
