Variable Rate TechnologyThe Good, The Bad, and The Ugly
• The bad – Focusing on the tools rather than the agronomy– My goal is to save input costs
• The ugly– Inferior application equipment– Untimely information
• The GOOD– We are past a lot of the growing pains associated with
VRT– VRT is profitable and is the “way” of farming tomorrow
Variable Rate TechnologyData Sources
• Aerial based image products• Grid soil samples• Electrical conductivity data• Yield data• Historical data
Variable Rate TechnologyEquipment
• Ground applicators– VR dry– VR sprayers
• Aerial Applicators– VR liquid– VR dry – Not quite there
• All systems vary the carrier volume• What is the next step in VRT?
– Direct injection
Variable Rate Technology
• Why farm with VRT?– Increase Net Profits
• HOW?– Reduced input costs– Increased yields– Environmental stewardship
We MUST accomplish ALL!!!

Location: Missouri Bootheel
Crop: Cotton
Field Size: 31.6 Acres
Imagery Acquired: September 1, 2005
VR Defoliation Applied: September 20, 2005
Notes:This prescription was applied
using a JD6500 equipped with a Raven Viper. The consultant was
