S01 Soil Physics Session: Soil Physics and Hydrology Student Competition: Lightning Orals (ASA, CSSA and SSSA Annual Meetings (Cincinnati, OH- Oct. 21

114 Soil Physics and Hydrology Student Competition: Lightning Orals

Oral Session

S01 Soil Physics The combined lightning oral and poster sessions welcome student contributions in Soil Physics and Hydrology. The lightning oral session is an essential precursor to the student poster competition later in the day. In this "lightning" round, students are given 3 minutes to verbally introduce their posters. No more than 2 slides can be used for visual aids. Student authors will also be present at the poster session to describe the research in detail and answer questions, as usually done in poster sessions. Judges will be anonymous.
