Symposium--The Soil-Crop Nexus Across Spatial and Temporal Scales (includes Global Digital Soil Map Graduate Student Competition)

Oral Session

ASA Section: Global Agronomy

Soil and crop responses vary across escalating spatial and temporal scales. In this symposium we focus on enhancing our understanding of the complexity of soil-crop systems, interrelationships between soils-crops, their up and downscaling behavior, the spatial distribution of soils across climatic , biotic, ecological, and topographic trajectories, and temporal evolution of soil-crop systems in response to imposed stressors (e.g., climate change) and limitations (e.g., nutrient limitations, soil degradation). To aggregate, synthesize, and integrate our knowledge on soil-crop systems from local, regional, to global scales will be discussed in this symposium.
