Quality Control Verification and Mapping System for Chemical Application

The quality of an agrochemical application is a combination of the efficacy of the deposit, the productivity of the operation and the avoidance of off-site movement. Potential environmental contamination from chemical application is influenced by the characteristics of application and proximity to sensitive areas. When small droplets, high spacing of boom above target or high ground speeds are used, off-target movement can increase. Similarly, when the application vehicle is near field boundaries or in significant wind conditions, off-target movement is more likely. Current GPS and GIS technology allow critical parameters of application to be sensed and recorded along with vehicle location. From these data, “quality control maps”, that is, historical records of the application can be generated and used to establish driver productivity, regulatory compliance or efficacious application.
