摘要

IT is eye-opening when you work with the best soil formation in the world here in Iowa, and then elsewhere see soil with only a few inches of depth and scratch through it with your hand to find bedrock! That's how I, an Iowa State University Extensionagronomist, sum up my recent visit to Guam, a small island nation in the Pacific Ocean. Recently, I was in Guam attending a soil carbon conference organized by the University of Guam. Scientists from the U.S., China and other Pacific Rim islands attended and presented at the conference. We had a chance to visit several research farms and farmers'fields.
