The next Agronomy and Horticulture seminar is April 4
Michael Kaiser, assistant professor of applied soil chemistry in the Department of Agronomy and Horticulture at the University of Nebraska–Lincoln, will present “Impact of Land Use on the Storage and Turnover of Soil Organic Carbon: Stories from the Subsoil,” on Thursday, April 4 at 11 a.m. in Keim Hall 150 or streamed live via Zoom at https://go.unl.edu/seminars.
Land use change is one of the main drivers of organic carbon storage in soils but significant knowledge gaps exist towards the response of biogeochemical cycles in the subsoil. In this seminar, Kaiser will present and discuss data from more than 20 sites in Nebraska. At these sites he sampled soil under cropland, native prairie or forest down to depths of at least 3 meters. The samples were analyzed for carbon storage and turnover, ecologically relevant carbon fractions, microbial community structure and soil mineral characteristics. The data of these analyses can help to develop improved land use strategies to increase the long-term carbon storage beyond the topsoil.
