Soil organic carbon content: Decreases partly attributed to dilution by increased depth of cultivation in southern Ontario
Researchers analyzed soil organic carbon contents and depths of Ap horizons (i.e., cultivated topsoil) from Ontario soil survey reports from 1950 to 2019.
Crop rotations differ in soil carbon stabilization efficiency, but the response to quality of structural plant inputs is ambiguous
This study set out to evaluate crop rotation diversity, perenniality, carbon inputs, and carbon input quality as predictors of soil organic carbon concentration and aggregate
Long-term diverse rotation alters nitrogen cycling bacterial groups and nitrous oxide emissions after nitrogen fertilization
This study measured the impact of 35 years of crop rotation diversification on soil microbial communities and nitrous oxide (N2O) emissions.
