The Impact of Each Droplet - Part 1

A spray application (platform-agnostic) primer in droplet size terminology and industry standards. Topics covered include droplet size statistics, droplet spectrum categories, coverage and drift potential. As the first course in a same-titled series, it lays the foundations for more in-depth courses centered around optimizing aerial spray applications.
