Abstract

Grazing management affects ecosystem function through impacts on soil condition. We investigated the effects of long-term (over 70 years) grazing on soil properties and nitrous oxide (N2O) emission within a moderately grazed native vegetation pasture (MGP), heavily grazed native vegetation pasture (HGP), and a fertilized crested wheatgrass (Agropyron desertorum (Fisch. ex. Link) Schult.) pasture (FCWP) near Mandan, ND, USA. Grazing-induced changes in species composition and N fertilizer application contributed to differences in soil properties and N2O emission between pastures. Soil organic C (SOC) was 5.7 Mg ha-1 greater in FCWP and HGP than MGP at 0-5 cm, whereas HGP had 2.4 Mg ha-1 more SOC than FCWP and MGP at 5-10 cm. At 30-60 cm, SOC in FCWP was 4.0 and 7.5 Mg ha-1 greater than in HGP and MGP, respectively. Particulate organic matter (POM) C and N in the surface 5 cm of FCWP were three- and five-fold greater, respectively, than in HGP and MGP. Acidification from N fertilization in FCWP decreased soil pH and cation exchange capacity compared to HGP and MGP in the surface 5 cm. Annual N2O emission was over three-fold greater in FCWP compared to HGP and MGP, and was positively associated with POM-C across all pastures (P < or = 0.0001; r2 = 0.85). Results from this study suggest fertilized crested wheatgrass enhances deep storage of SOC, but contributes to surface acidification and greater N2O emission relative to native non-fertilized pastures in the northern Great Plains.

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

  • Annual nitrous oxide emission from a crested wheatgrass pasture fertilized with synthetic nitrogen was 3.4 kg N ha-1 year-1, equating to 1.6 Mg CO2e ha-1 year-1.

    “Annual N 2 O emission from a crested wheatgrass pasture fertilized with synthetic N was found to be 3.4 kg N ha -1 year -1 [19], equating to 1.6 Mg CO 2 e ha -1 year -1 , or approximately 40% of the C sequestration rate at 0-30 cm observed across sites in this study.”

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.
