Abstract

Fine-root production and turnover were estimated in a short-rotation stand of basket willow (Salix viminalis L.) in central Sweden. Different calculation methods, based on soil coring, or combinations of soil coring and minirhizotron technique, were used. Fine-root biomass production and mortality in the 0–50 cm soil horizon were estimated at 900–7200 kg ha−1 yr−1 and 500–6800 kg ha−1 yr−1, respectively, depending on the method used. Corresponding values for production and mortality of fine-root length per unit soil volume were 160–1600 dm dm−3 yr−1 and 40–1500 dm dm−3 yr−1, respectively. Methods based on soil coring alone gave the lowest estimates, and probably underestimated production and mortality, since both processes to a high degree occurred simultaneously in the willow plantation. Thus, this study emphasizes the necessity to separate the processes of growth and decay where high fine-root turnover occurs.

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

  • Belowground biomass components enter soil organic carbon pools dependent on their mortality and longevity.

    “BGB components will enter the SOC pools dependent on their mortality/longevity [30–32].”

    From Carbon Sequestration by Perennial Energy Crops: Is the Jury Still Out? (2015) · cites this paper as [32]

  • Data for carbon inputs from belowground biomass are difficult to interpret, especially for roots, because they are based on many single observations rather than time series.

    “Data for C inputs from BGB are difficult to interpret, especially for roots because they are based on many single observations [45, 61, 62, 64, 80] rather than time series [26, 32, 81–83].”

    From Carbon Sequestration by Perennial Energy Crops: Is the Jury Still Out? (2015) · cites this paper as [32]

  • Inputs were often based on snapshots, while detailed time series were the exception, especially with regard to root production and turnover.

    “It is important to realise that inputs were often based on snapshots, whilst detailed time series were the exception, especially with regard to root production and turnover [32, 81, 82].”

    From Carbon Sequestration by Perennial Energy Crops: Is the Jury Still Out? (2015) · cites this paper as [32]

  • A small number of studies using isotopes, model systems and field sampling allow scaling of mean residence times to in situ rates.

    “However, a small number of studies using isotopes [109], model systems [110, 111] and field sampling [32, 81, 82] allow their scaling to in situ rates.”

    From Carbon Sequestration by Perennial Energy Crops: Is the Jury Still Out? (2015) · cites this paper as [32]

  • The longevity of fine willow roots can range between 55 and 350 days.

    “The longevity of fine willow roots can range between 55 and 350 days [32, 58, 83].”

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.
