Pairing soil sampling with very-high resolution UAV imagery: An examination of drivers of soil and nutrient movement and agricultural productivity in southern Ontario

•UAV-based digital terrain model is used to map topographic variation and erosion flow pathways.•Water content and organic matter are primary controlling factors on crop yield.•Soil and nutrients move in erosional pathways in the lower portion of catch basins.•Novel opportunities for integrating UAV data and soil sampling for time-series analysis.
