Expert to discuss contemporary nitrogen challenges

PULLMAN – Paul Fixen, international soil fertility expert, will speak on agricultural science and policy to sustain a world of 9 billion people, with an emphasis on nitrogen. The seminar will be held Monday, Oct. 26 at 2:10 p.m. in Room T101 of the food science and nutrition building.
Nitrogen in commercial fertilizer accounts for approximately half of all nitrogen reaching global croplands today and supplies basic food needs for at least 40 percent of the world’s population. Fixen’s talk will focus on the challenges facing science and industry to continue to help meet that need while minimizing the risk of negative environmental impacts through improved nitrogen-use efficiency.
Fixen is senior vice president, America’s group coordinator and director of research of the International Plant Nutrition Institute of Brookings, S.D. He coordinates the institute’s activities in North and South America and directs its research program.
The event is sponsored by the department of crop and soil sciences, the Center for Environmental Research, Education, and Outreach, and the Nitrogen Systems: Policy-oriented Integrated Research and Education Program.
The seminar is free and open to the public. Video conferencing is available upon advance arrangement. Contact Debra Marsh, 335-2615 or
