Long-term study reveals best practices for building soil carbon in agricultural soils

2.25.25

Soil Profile

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

Drought effect on pore structure in soils: Reflections from an LTER Fellow

Goutham Thotakuri is a graduate student in the Kravchenko lab at Michigan State University. His research is focused on the study of carbon transfer between various cover crop species and soil carbon sequestration. Recent changes to our climate dynamics have brought on alarming drought conditions in many parts of the world. Since we cannot control the climate, we need to prepare our agricultural systems for adversity.  One way to do this is through understanding the soil's hydro-physical and biochemical processes. We can identify critical factors influencing drought resilience by

Little strips of prairie can go a long way

8.1.22

A narrow green strip of prairie runs through a wheat field.

New research out of MSU shows that it is possible to manage farmland to address two challenges simultaneously – protecting biodiversity and maintaining ecosystem services. The key is to strategically place native perennial vegetation within agricultural systems, using the innovative practice of prairie strips. Today, 38% of the landscape in the Midwest is planted in row crop agriculture. “We need to make this land habitable for species for the ecosystem services the increased biodiversity can provide to the farms” said Lindsey Kemmerling, the first author of the MSU-led study

A new perspective – using bioenergy crops to alleviate global warming: Reflections from an LTER fellow

Jinho in the lab

Jinho Lee is a PhD student in the Plant, Soil and Microbial Sciences Department at Michigan State University. He works in the Kravchenko lab with interests in carbon dynamics of soil. Today we are facing one of the biggest environmental challenges that our species has never faced, and one that is caused by our own actions. Since the Industrial Revolution, the worldwide carbon dioxide (CO2) emissions have increased due to use of C-based fossil fuels. This has resulted in global warming.  To alleviate global warming and reduce the dependence on fossil fuels, several alternative

Understanding the role of microbial diversity in soil ecosystem functioning: Reflections from a LTER Fellow

8.31.20

Grant Falvo is a PhD student in the Plant, Soil and Microbial Sciences Department at Michigan State University. He works in the Robertson lab within the disciplines of soil microbial ecology and biogeochemistry and is interested in global change phenomena broadly. There are more microorganisms in a typical handful of soil than there are people on this planet. Every year these microbes emit >5 times as much CO2 as all the fossil fuel emissions emitted by humans. Yet recent research is beginning to uncover the dominant role these microbes play in stabilizing a similarly large

Using prairie strips to understand the value of diversifying agricultural landscapes: Reflections from an LTER Fellow

2.6.20

MSU graduate researcher, Lindsey Kemmerling, is a PhD student in Dr. Nick Haddad's lab at Michigan State University's Kellogg Biological Station. Society today faces three immense ecological challenges: preventing the loss of biodiversity, adapting to climate change, and sustainably supporting a growing population. Humans have caused a global biodiversity crisis, with new studies continuing to reveal stunning rates of biodiversity decline across the entire tree of life. Simultaneously, we are presented with the challenge of sustainably and equitably supporting a growing human
