Manure management seminar set




Seminar series to focus on manure management

The Iowa State University Department of Animal Science is launching a
weekly seminar series on manure management issues in sustainable
agriculture.

The series, which is open to the public at no cost, will feature
presentations and discussions on livestock issues in Iowa, including
confinement units, grazing, odor, and sociological aspects of incorporating
livestock into farming operations. All sessions will be held on Thursdays
at 4:00 p.m. in Room 2050 of the ISU Agronomy Building.

The weekly series begins on Jan. 19 with a presentation on the Leopold
Center for Sustainable Agriculture at ISU by center director Dennis Keeney.
On Jan. 26, ISU agricultural and biosystems engineer Stewart Melvin will
discuss environmental considerations for the size of animal enterprises; on
Feb. 2 ISU agricultural economist Mike Duffy will describe micro- and
macro-economic aspects of animal waste management. The seminars conclude on
April 20.

The series, which is also offered for graduate credit, is jointly supported
by the ISU College of Agriculture departments of animal science, agronomy,
agricultural and biosystems engineering, entomology, forestry, sociology,
economics, and the Leopold Center for Sustainable Agriculture. For a
complete list of topics to be covered in the seminar, contact Jim Russell
at 294-4631.
