453 Symposium--Soil Change: Agronomic, Ecological, and Pedologic Process Measurements and Modeling: Title: I

Oral Session
SSSA Division: Soils & Environmental Quality
A cross-divisional symposium will bring together invited speakers and volunteers (posters) to present an integrated vision of agronomic, ecological and pedologic principles related to contemporary soil systems and management. Most soils are human-natural systems, often changing in unprecedented ways. Presenters will share information on established and planned long-term experiments, such as CZOs, LTARs, LTERs, LTSEs, ISCN and NEON sites, to discuss issues common to long-term research, such as scaling and variability of soil response to human activity. Three questions will be addressed:  1) How are soils changing in response to human and natural forcings?  2) How do we measure and model on-going soil change?  3) What are implications of soil change for society and the environment?
