In 2015, Tom and Jason ran demonstrations at Ontario’s Southwest Agriculture Crop Diagnostic Days. The 20 minute sessions were designed to explain:
- The phenomenon of pressure drop,
- how to measure it,
- how to correct for it, and
- how low pressure affects coverage.
Although manufacturers of air induction nozzles often rate their performance as low as 15 psi, such a low pressure collapses the spray pattern and the resulting gaps reduce coverage. Additionally, the spray quality at such low pressures is coarser than at higher pressures, reducing the number of droplets available. This further reduces coverage potential.
Here’s a Power Point presentation on the topic:DOWNLOAD
This video covers the key speaking points from that demonstration.
