Spring always brings renewed interest in sprayer calibration. This is good, because a well-maintained and calibrated sprayer will protect crops more effectively and efficiently, as well as reduce the potential for off-target drift and point source contamination. Presently, there is no nationally-recognized standard for sprayer calibration in either Canada or the United States. As a result […]

This is part one of a two part article on how to optimize the match between the sprayer air and the target canopy. For a more fulsome description of the process, consult chapters 3, 9, 10, and 11 of Airblast101. Why is air so important? Air handling is the most important and least understood mechanical […]
