The final day observing KBS research before heading to the GLBRC Institute was with Sarah Roley. The project that took a majority of the time was to collect residue from last year's switchgrass growth. We took a .625 meter quadrant and placed it three times in each plot. Once it was placed, we collected any dead organic material from switchgrass and placed it into the a bag. Each plot had it's own bag, which became quite a collection in the trunk! The residue will be dried in the field lab and then the nitrogen will be measured.

Another collection, was gas samples from within the soil. Sarah introduced a gas through a tube that went 20 centimeters deep. She then drew samples from 3 different locations near the introduction at different depths. The goal is to see how nitrogen is dispersed within the soil, but she is testing the methods with a cheaper has until it is fine tuned.

While at the GLBRC plots, a group from the World TAP conference stopped by for a tour with Dr. Stephen Hamilton and Julie Doll from the LTER education. The group were professionals and leaders from Africa, Asia, South America...collaborating and learning about technology and agriculture from around the world.
