New Papers on Cover Crops

Congratulations to Alison and Etienne! Alison’s paper in Society & Natural Resources reports findings from a case study showing how the National Wildlife Foundation’s Cover Crop Champions program leverages strategic communication methods and farmer networks to increase cover crop adoption.

Etienne’s paper in Ecosphere, based on a literature review and a field experiment conducted at the UM Campus Farm, highlights the role of intraspecific trait variation in explaining ecosystem services from cover crops.

Etienne receives Rackham Public Scholarship Grant

Etienne is a 2021 recipient of the Rackham Public Scholarship Grant– a program that supports graduate student projects that are co-created and mutually beneficial for students and community partners. This funding enables Etienne to work collaboratively with farmers across the Great Lakes Region. Read more about the Rackham Program in Public Scholarship along with details on Etienne’s citizen science data collection project here.

Congratulations, Kent!

Kent and Jennifer’s proposal to the Graham Institute Carbon Neutrality Acceleration Program was funded! The experiment will test the capacity for legume-grass cover crop mixtures to simultaneously supply nutrients to crops and sequester carbon in soil. The project will use soil from working farms in Michigan that have a range of different properties, which will help our research account for the real-world variability in soils that farmers consider when making management decisions.

New paper uses indicator framework to link ecological and nutritional functions of agroecosystems

Congratulations, Anne Elise! Anne Elise’s new paper in Frontiers in Sustainable Food Systems presents an indicator framework linking ecological and nutritional functions of agroecosystems. The paper applies the framework and indicator set to a case study of Q’eqchi’ Maya smallholders in eastern Guatemala, using farm management and crop quality data from 60 households to determine the status of agroecosystem functions and assess coping and adaptive capacities in response to shocks.

Recent Publications

A new forum paper in BioScience discusses critical research needs to better link changes in soil health on farms to watershed-scale reductions in nitrogen and phosphorus losses that cause water pollution.  The paper emerged from a workshop on improving models of nutrient loading and harmful algal blooms coordinated by the Michigan Environmental Council and by the Cooperative Institute for Great Lakes Research (CIGLR).

Two new articles from our cover crop research on vegetable farms in southeastern Michigan focus on understanding variation in root functional traits, and ecological controls on legume nitrogen fixation, across a soil organic matter gradient:

New Funding for Ongoing Brazil Research

Congratulations to Anne Elise and Jennifer, Co-PIs on a new grant funded by the Conservation, Food, and Health Foundation, and led by a Brazilian NGO collaborator, CEPAGRO (Center for the Study and Promotion of Community Agriculture). The project, “Next Generation Cover Crops: Driving Innovation in Soil Management with Participatory Certification,” will support on-farm cover crop research and capacity-building with farmers transitioning to agroecological production in southern Brazil.

New USDA-funded Research Project

We are excited to tackle a new research project funded by the USDA-AFRI Foundational Program on cover crops and ecosystem services from field to landscape scales. The project links a field experiment, remote sensing, on-farm research, and stakeholder engagement. We will determine how ecosystem services from cover crop mixtures vary with different management legacies and soil conditions, understand the current adoption and outcomes of different cover crops across diverse regions of Michigan, and identify relationships between cover crops and nutrient mass balances on working farms.
