We have posted guidelines and worksheets to help growers calibrate their overhead frost protection systems.
The calibration uses buckets (collectors) arranged in series on adjacent rows to measure the application rate and the uniformity of application along the cordon. In essence; set out the buckets, run the system for a set time, measure what’s collected and do some sums. Shouldn’t be too hard?
Please do let us know how you get on though. We’ve had a quick try, but it is only when lots of people try to follow our guidelines, and gain experience, that any niggles show up.
