Environmental and economic value of soil services
Healthy soils provide essential ecosystem services (e.g. nutrient recycling, carbon sequestration, climate regulation, and water filtration) that sustain plants, animals, and humans. The growing trend towards simplifying systems in Ontario and the nort …

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.
News:
Past management impacts phosphorus availability
The corn-soybean rotation is the dominant cropping system on farmland throughout central Canada and the midwestern United States. However, long-term …
Nitrogen inhibitors reduced N2O emissions without permanently changing soil microbial communities
Using fertilizer efficiently is vital for managing agroecosystems sustainably. It makes the most of crop productivity while protecting the environment. …
