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.

Legume Cover Crop Management on Nitrogen Dynamics and Yield in grain corn systems

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 size.

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.

Greenhouse gas emissions from gradually-filled liquid dairy manure storages with different levels of inoculant

Liquid dairy manure storages emit large amounts of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). Gradually filling manure storages is a standard practice, however, most studies have batch filling approaches. Gradual manure filling may emit diff …
