To evaluate the impact of agricultural management practices on soil organic carbon stocks across Canada and provide verifiable stock change factors and uncertainties for greenhouse gas accounting.
Compiled and synthesized published data from 62 long-term field studies across Canada.
Evaluated differences in soil organic carbon stocks resulting from the conversion of native land to cropland, tillage regimes, crop rotations, and fertilizer inputs.
Derived stock change factors and uncertainty ranges relative to control treatments for use in empirical IPCC-style models.
Conversion from native land to agricultural cropland resulted in a 24 ± 6% loss of soil organic carbon.
Adoption of no-till increased soil organic carbon storage by 2.9 ± 1.3 Mg ha⁻¹ in western Canada, but showed no increase in eastern Canada.
Soil organic carbon storage consistently increased with no-tillage, reduced summer fallow, wheat-hay rotations, green manure incorporation, and nitrogen or organic fertilization, though no-till potential declined with higher baseline carbon levels.
