Summary
This meta-analysis by McDaniel et al. (2014), published in Ecology Letters, synthesises evidence on the relationship between plant diversity and soil carbon stocks. The study likely finds that greater diversity in cropping or plant communities is associated with increased soil organic carbon, drawing on data from multiple experimental systems globally. The findings contribute to the evidence base linking biodiversity-informed management with soil carbon sequestration potential.
UK applicability
Although the study is international in scope, the findings are broadly applicable to UK arable and mixed farming systems where diversification strategies — such as cover cropping, rotational diversity, and intercropping — are increasingly promoted under agri-environment schemes and post-Brexit agricultural policy frameworks.
Key measures
Soil organic carbon (g C kg⁻¹ or Mg C ha⁻¹); species/crop diversity indices; effect sizes across studies
Outcomes reported
The study examined how plant species diversity influences soil organic carbon stocks, likely reporting effect sizes across varying levels of crop or vegetation diversity. It probably quantified the relationship between diversity metrics and soil carbon accumulation or retention.
