Map of systematic soil sampling. NEON’s 30-year sampling strategy for monitoring ecosystem productivity and biogeochemistry includes co-located measurements of plant structure, biomass, soil and plant biogeochemistry, and microbial populations. The resulting data can be used to address a wide variety of questions related to ecosystem science. This overview focuses on the measurements associated with two specific components of this design: soil biogeochemistry and microbial diversity (page 2), and plant structure and biogeochemistry (page 3). Scaling point measurements of these ecosystem components across space relies heavily on NEON’s Airborne Observation Platform (AOP), which will fly over all NEON sites annually to collect . Yifei.
