Abstract

Grasslands are heavily relied upon for food and forage production. A key component for sustaining production in grassland ecosystems is the maintenance of soil organic matter (SOM), which can be strongly influenced by management. Many management techniques intended to increase forage production may potentially increase SOM, thus sequestering atmospheric carbon (C). Further, conversion from either cultivation or native vegetation into grassland could also sequester atmospheric carbon. We reviewed studies examining the influence of improved grassland management practices and conversion into grasslands on soil C worldwide to assess the potential for C sequestration. Results from 115 studies containing over 300 data points were analyzed. Management improvements included fertilization (39%), improved grazing management (24%), conversion from cultivation (15%) and native vegetation (15%), sowing of legumes (4%) and grasses (2%), earthworm introduction (1%), and irrigation (1%). Soil C content and concentration increased with improved management in 74% of the studies, and mean soil C increased with all types of improvement. Carbon sequestration rates were highest during the first 40 yr after treatments began and tended to be greatest in the top 10 cm of soil. Impacts were greater in woodland and grassland biomes than in forest, desert, rain forest, or shrubland biomes. Conversion from cultivation, the introduction of earthworms, and irrigation resulted in the largest increases. Rates of C sequestration by type of improvement ranged from 0.11 to 3.04 Mg C·ha−1 yr−1, with a mean of 0.54 Mg C·ha−1·yr−1, and were highly influenced by biome type and climate. We conclude that grasslands can act as a significant carbon sink with the implementation of improved management.

  • For most management techniques in grasslands, average relative gains in SOC in the 0-0.3 m horizon are of the order of 1-2% per year, corresponding to average sequestration rates of 0.3 Mg C ha-1 yr-1.

    “In a global meta-analysis, Conant et al. [26] suggested that for most management techniques in grasslands, such as fertilization and improvement of grazing management, average relative gains in SOC in the 0–0.3 m horizon are of the order of 1–2% per year, corresponding to average sequestration rates of 0.3 Mg C ha-1 yr-1.”

  • Fertilizer additions to grassland systems have shown to increase SOC and root C storage but overall changes varies by soil type and climate.

    “Fertilizer additions to grassland systems have shown to increase SOC and root C storage but overall changes varies by soil type and climate (Conant et al., 2001;Ma et al., 2001;Lee et al., 2007;Heggenstaller et al., 2009;Blanco-Canqui, 2010).”

  • Restoration of marginal or degraded lands to perennial forest or grassland increases soil C storage, although usually at a slower rate than the original conversion losses.

    “Conversely, restoration of marginal or degraded lands to perennial forest or grassland increases soil C storage (Fig. 1), although usually at a slower rate than the original conversion losses 15,16”

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.
