  1. Sorting Through the Layers Of Precision Agriculture Farmer Smarter Conference Lethbridge, AB, December 4, 2013 Ken Coles M.Sc. P.Ag.

  2. 1.Producer knowledge 2. Aerial Imagery/Orthophotos 3.Soil Apparent Electrical Conductivity (ECa) Mapping Sensors 4. Digital Elevation Models (DEMs) 5. Yield Maps 6. Aerial Imagery from UAV –based Sensors 7. Satellite-based NDVI imagery 8. Ground-based vegetation sensors (greenseeker) 9. Grid soil sampling

  3. Understanding Soil Variability for Effective Zone Management in Precision Agriculture – an evaluation of sensor based soil mapping tools. • Multidisciplinary team of experts in precision agriculture, agronomy, soils, GIS, spatial statistics, remote sensing, salinity, economics • Data collection: all layers, EC twice per sensor, field scale replicated response trials • Evaluate multiple zones after the fact using field trial, conventional and spatial stats.

  4. Variable Rates: Nitrogen (lbs/ac): 0, 30, 60, 90, 120 Seeding Rates (seed/m2): 250 , 350

  6. Lessons: • Trying to do anything with Ag GPS beyond auto-steer is like herding cats! • Calibration is critical • Accurate GPS is important for minimizing error • Constant and reasonable speeds are required • Soil moisture important, frost free window is small • Veris more costly & slower but can add OM and pH sensor • The devils in the detail!
