AMES, Iowa — The Iowa Learning Farms (ILF) conservation webinar taking place Nov. 13, at noon CST will feature Wenjuan Huang, assistant professor of Ecosystem Ecology and Soil Biogeochemistry in the Department of Ecology, Evolution, and Organismal Biology at Iowa State University. Huang’s research focuses on soil carbon and nutrient cycling both in nature and managed ecosystems, with the aim to improve soil health and mitigate climate change. She integrates field measurements, lab incubation and mechanistic models to understand how plant-microbial-mineral interactions affect soil carbon persistence and nutrient availability/retention.
In the webinar, “Can Diversified Cropping Systems Help Increase Soil Carbon Storage?,” Huang will discuss ongoing research to highlight her approach to soil organic carbon (SOC) measurement in diversified cropping systems. She will share methods employed to integrate a 20-year field experiment and laboratory measurements with three stable-isotope-enabled mechanistic models to examine organic carbon (SOC) stocks to 1 m in a conventional corn-soybean system and two more diversified systems including small grains, legumes, and manure inputs in addition to corn and soybean. Huang will draw on this research to discuss observations and expected outcomes that may reveal the underlying mechanisms by which diversified cropping systems might alter decomposition and the response of C pools with different residence times.
“While it is generally agreed that diversified cropping systems offer a chance to mitigate the environmental impacts of conventional agriculture, there is still much debate surrounding the impacts on soil organic carbon sequestration,” said Huang. “Through this research, we hope to better understand and seek to quantify how diversified cropping systems affect soil carbon and how this knowledge can help us to promote healthier soils and more sustainable farming practices. Agricultural soils cannot be simply viewed as ‘buckets for carbon’, they are complex systems in which sequestration can vary based on numerous conditions that we are seeking to understand.”
Participants are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
