Scaling plant nutrient use in peatlands.
A natural gradient of nutrient-limited peatland ecosystems at the University of Notre Dame Environmental Research Center in the Upper Peninsula of Michigan, USA were fertilized between 1998 and 2002 with nitrogen, phosphorus, or a combination of both nutrients. Our objectives were to determine how changes in carbon and nitrogen partitioning within a plant, and changes in community composition, would affect plant nitrogen-use efficiency.
