Carbon Sequestration in Soils at Carleton College: Current Practices and Future Recommendations

Students in Mary Savina’s Fall 2014 Geology of Soils class provide an assessment of the potential impact that carbon sequestration by soils at Carleton could have by presenting Geographic Information Systems (GIS) data on the area of campus that could be converted to a groundcover that would maximize carbon sequestration by soil.

SERC InTeGrate Project

The Science Education Resource Center (SERC) works to improve education through projects that support educators. InTeGrate is a specific SERC project funded by a 5-year STEP Center grant from the National Science Foundation. The program supports the teaching of geoscience in the context of societal issues both within geoscience courses and across the undergraduate curriculum. Our goal is to develop a citizenry and workforce that can address environmental and resource issues facing our society.

Northfield Energy Task Force

The Northfield Energy Task Force (NETF) was created by resolution of the Northfield City Council in May 2007 to respond to challenges presented by reliance on fossil fuels and climate change. Their report, “With Hope: A Resilient Community” was presented to the City Council in May 2008, but follow-up was limited due to other political priorities at the time.

Study of Agricultural Tillage Practices

 Description: Undergraduate collaborators work directly with faculty, the CRWP, and area farmers to examine the effects of different agricultural practices on soil quality and agricultural yields. Past research has examined water runoff and the diversity of invertebrate soil fauna associated with different tillage methods, especially no-till and strip-till. Lands owned by farmer participants as well as St. Olaf College are used as field sites. In additional a special project examined tillage practices and carbon sequestration with the possibility of local carbon offsets. Recent research has focused on exploring how differences in applied nitrogen fertilizer translate into soil nitrogen levels, stalk nitrate levels, and product yield. Additionally, research work focuses on general indicators of soil quality including moisture levels, compaction, organic carbon and nutrients, including nitrogen and phosphorous.

Participants:

  • David Legvold, farmer
  • Gene Bakko, St. Olaf College (retired)
  • Kathleen Shea, St. Olaf College
  • Megan Gregory ‘04, St. Olaf College
