112 Sensor-Driven Digital Soil Mapping: I

Oral Session
S05 Pedology

Soil sensors (diffuse reflectance spectroscopy, electromagnetic induction, and others) and remote sensors derive proximal soil and environmental data that are incorporated into spatially-explicit soil prediction models. This session will focus on advancements in sensor technologies and synthesis with field and lab-derived data into complex soil prediction models. Uncertainty and accuracy of sensor-derived data will be given special attention.
