Brandon Kristy, a Ph.D. student in the Department of Integrative Biology and a member of the Evans Lab at the Kellogg Biological Station, will go to Lawrence Livermore National Laboratory, or LLNL, to study the "unseen" partners of sustainable bioenergy.Kristy’s specialty is plant science for sustainable bioenergy, where he investigates how soil microbiomes can help crops like switchgrass thrive without relying on excessive chemical fertilizers. Kristy's work underscores how MSU graduate students are leveraging national resources to turn fundamental scientific inquiry into real-world s
MiSTRIPS impacts farmers beyond their fields
The MiSTRIPS program is helping Michigan farmers boost soil health, support wildlife, and increase profit by integrating native prairie strips into working farmland, making a meaningful impact and fostering new relationships between land stewards and researchers. The MiSTRIPS program has supported 11 Michigan farmers in planting more than 50 acres of native prairie and prairie strips, creating meaningful change across agricultural communities and building strong connections between land stewards and scientists. Farmers from across the state have joined MiSTRIPS over the past five years,
Graduate research from the KBS LTER reveals how nematodes contribute to soil food web stability in droughts
Using the Rainfall Exclusion Experiment (REX) within the KBS LTER, researchers found that nematode communities are more stable in early successional landscapes than agricultural ones during drought. This study highlights the importance of plant diversity for resilient soil ecosystems under environmental change. As farmers adopt new strategies to cope with increasingly extreme weather events, such as heatwaves and droughts, understanding the mechanisms behind resiliency in agricultural systems is critical. While it’s well-established that drought harms crop production, less is known about h
Collaboration between Michigan farmers and LTER researchers provides insights into soil health at the margins of agricultural fields
The multi-year collaboration aims to leverage farmer knowledge and experience and combine it with soil sampling to determine how soil conditions are impacted by being on the edge of agricultural fields, leading to useful management recommendations for creating productive farmlands. Intensive agriculture requires widespread adoption of conservation practices to mitigate loss of ecosystem services. Planting native perennial vegetation at the edge-of-fields (EOF) is a conservation practice shown to improve soil health and protect water quality. The deep root systems and stiff stems of
Long-term research at the KBS LTER reveals how changes in land use shape soil structure and carbon storage
Using high-resolution X-ray imaging, researchers from the KBS LTER tested soil samples from the LTER Main Cropping System Experiment and discovered that intensive agriculture continues to influence soil porosity and carbon content for decades after restoration to native habitat. Even after 35 years, restored soils contained only about 50% of the organic carbon found in native grasslands and forests. When it comes to agriculture, it’s not just about what’s in the soil, but also how the soil is structured. Given that much of our land is converted from native habitat to agriculture, it’s impo
Long-term study reveals best practices for building soil carbon in agricultural soils
Investigators at the KBS LTER site find differences in soil carbon gain among cover cropped, no-till, and perennial cropping systems after 25-years. Cover cropping found to be a powerful tool for building soil carbon even in cropping systems that are plowed. No-till and diverse perennial plantings also emerge as effective ways to build long-term soil carbon stores. Soil carbon, often called the foundation of soil fertility, plays a crucial role in enhancing plant water availability, supporting beneficial microbes and insects, improving drainage, and promoting nutrient cycling and
Trials and tribulations of a PhD student: Reflections from an LTER Fellow
Moriah Young is a graduate student at the Kellogg Biological Station and a member of Phoebe Zarnetske's Lab. Her PhD research seeks to understand the effects of climate change on soil biota, plant, and herbivore interactions. Using a combination of field and greenhouse studies, Moriah works to understand the ways in which the composition and structure of soil microbial communities respond to warming and drought, as well as describing the role that the soil microbial community has on plant traits, stress responses, and insect preferences in the presence of warming and drought. I went into
Article featuring KBS research wins outstanding paper award
A paper that examines best practices for improving soil health over time has been recognized as outstanding by the American Society of Agronomy, or ASA. The paper, spearheaded by W.K. Kellogg Biological Station resident faculty and MSU assistant professor Christine Sprunger, detailed research that was conducted at the KBS Great Lakes Bioenergy Research Center site. Tvisha Martin and Meredith Mann also contributed to the paper, titled “Systems with greater perenniality and crop diversity enhance soil biological health,” which was originally published in 2020 in the journal Agricultural a
Prairie strip ecology, art, and advocacy in the LTER: Reflections from an LTER Fellow
Corinn Rutkoski is a graduate student in Sarah Evan's lab at the Kellogg Biological Station. She is broadly interested in the use of perennials in agricultural systems, science policy, and soil health. Her research path has been propelled by a reciprocal inspiration among ecology, conservation, and creativity. In September 2018, Lisa Schulte Moore was scheduled to give a seminar at KBS titled Prairie strips improve biodiversity and multiple ecosystem services from corn-soybean croplands. At the time, I was a technician in Sarah Evans’ lab at KBS, considering graduate school b
Disentangling the complex effects of climate change on above and belowground communities: Reflections from an LTER Fellow
Graduate researcher, Moriah Young, is a Ph.D. student in Dr. Phoebe Zarnetske’s lab at Michigan State University. The lab uses open top chambers (OTCs) to study how biotic interactions and climate change directly and indirectly affect community structure and function at the KBS LTER. Climate change is a pressing threat to ecosystems around the world. From warmer temperatures to more unpredictable rainfall, climate change has shown to have a myriad of effects on ecosystems. Most research has focused on direct effects of climate change on species. For example, how does warming a
