In this project, we are examining the influence of root order, age, depth, and spatial arrangement on microbial recruitment. Whereas most studies of root-associated microorganisms use homogenized root systems, we seek to understand the fine-scale factors that shape root-microbe interactions at different points in space.
The primary work for this project takes place in an experimental vineyard at Rock Springs in Pennsylvania, using root visualization windows within 1 metre deep root observation boxes. This field setup is unique, and allows us to sample grapevine roots across a substantial depth profile. We are also proofing some of our approaches within a common garden forest that was established and is managed by Dave Eissenstat.
