Manure on Cropland is Good for More than Nutrients

MANHATTAN, Kan. — Manure provides nutrients for farm fields and
improves soil quality and tilth, but there are other implications to
its use.

Mark Risse, University of Georgia professor, will give an overview of
the science of manure to lead off the free monthly manure management
Webcast from eXtension Oct. 17.

Risse is one of three university specialists who will discuss the
impacts of manure application on runoff and soil erosion, water
holding capacity of soils and the need for irrigation during the Web-
based seminar that is open to the public.

They will discuss manure from an organic farm systems perspective and
discuss compost effects on soil quality. They also will discuss the
liming effect of some manures including poultry litter,
mineralization rates including carbon mineralization and salt
accumulation.

Washington State University researchers Craig Cogger and Ann-Marie
Fortuna will join Risse. Cogger is a soil scientist who has extensive
experience with compost methods and using biosolids. His current
research is on organic and sustainable cropping systems.

Fortuna is a faculty member in soil biology. Her research emphasis is
to determine the role of organisms in plant nutrient acquisition and
health and trace the fate of pathogens and beneficial organisms in
the environment.

The Friday, Oct. 17 session begins at 2:30 p.m. Eastern Daylight
Time. The Webcasts are hosted by the Livestock and Poultry
Environmental (LPE) Learning Center, an information resource
developed by more than 150 experts from land-grant universities,
agencies and other organizations. The center is part of the national
eXtension interactive Web resource customized with links to local
Cooperative Extension Web sites. Kansas State University Research and
Extension is part of eXtension.

The Webcast meeting room opens 15 minutes before the start time. Go
