Meeting agenda/notes

June 4, 2015

8:30-12:00 State Reports:

• Dan Olk: On-farm evaluation of a humic product in Iowa corn production.
• Paul Verburg: C storage in desert shrubland converted to irrigated agriculture
• Matt Ruark: Crop systems diversity, POM and aggregates
• Lisa Tiemann: Drivers of soil fertility loss and consequences for soil sustainability in Uganda
• Peter Motavalli: Flooding and land used effects on ghg emissions. After flooding takes a while to redox low enough for CH4 emissions.
• Larry Cihacek: Challenges of measuring bulk density in sandy soils. P mineralization from distillers grain.
• Mike Castellano: Nitrogen use efficiency as affected by soil organic matter
• Michelle Wander: Models, cooperation with Oak Ridge
• Ron, Rhae and Sandeep elected not to present.
