What we needed to do Precision Agriculture?
• Ca. 10 years ago….– The 3 required components of PA: Sensors, GPS
& GIS– Needed to establish Management Zones – MZ (…
if significant variability in soil or crop properties exists…)
– Lastly, use Variable Rate Technology for precise application of production inputs, based on predetermined MZs

What we need to do Precision Agriculture in the near future?
• Rapid developments in cutting-edge technologies….
• The required component: Validated Sensors!• Validated crop-soil simulation models!• Long term ( to evaluate temporal as well as
spatial variability) validated financial results at “farmer’s pocket” and “soil-crop-atmosphere” level!

What we need to do Precision agriculture…next?
• Latest developments……– UAVs (Unmanned Aerial Vehicles) Drones or 4 or 6
or 8 Chopters, – equipped with multispectral & broadband cameras
– Ground located sensors (for “ground truthing”)– “On-the-go” systems , i.e. for N precision
fertilizations, herbicide on the spot, etc.– EZ-guide systems (GPS based sensors)– Robotics… harvesting automations!– Note: “Validated” means not just “calibrated”!
