Long Term Field Trials To Examine Yield, Soil Productivity, And Environmental Impacts Of Ontario Corn, Soybean And Wheat Production Systems
Using the long-term rotation experiment near Elora, ON (established 1980) to study the impacts of tillage and diversity of crop rotations on a number of agri-environmental factors.

Publications:
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. …

Awesome first conference talk by MSc student Alexis De Laronde, talking about soil diversity and cover crops! @UofG_SES @csm_scm2022
Hey, we know her! 😀👋 That’s LOC co-chair @CMKhursigara (on screen) and LOC co-chair @karidunfield, who (along with @yostlab) is the co-EIC of our Canadian Journal of #Microbiology. Come by Booth 16 today and tomorrow to say hi and learn more about our journal! @csm_scm2022 https://twitter.com/csm_scm2022/status/1541188447469293569
The keynote kicks off with an address with LOC chairs @CMKhursigara and @karidunfield
