How do you test sprayer uniformity in a new field?

• A. Check nozzle color and guess uniformity.
• B. Calibrate by spraying into a marked area or catch pan and measure output to verify even distribution.
• C. Rely on manufacturer claims without field checks.
• D. Weigh the entire sprayer before and after to estimate output.

Answer: (B)

Testing sprayer uniformity means confirming that the spray is distributed evenly across the field at the intended rate. The best way is to calibrate by spraying into a marked area or catch pans and then measuring what comes out in each zone. This gives real, field-accurate data on how evenly the product is being deposited, so you can spot and fix issues like worn nozzles, inconsistent flow, pressure differences, or spacing problems and adjust nozzle choice, pressure, or spacing to achieve uniform application. Set up a small grid with marked areas or place catch pans at representative locations, spray at the target rate, then measure the liquid collected in each area. Compare the results to the desired rate to verify even distribution and identify any outliers that need correction. Relying on nozzle color isn’t reliable for uniformity, and manufacturer claims may not reflect field conditions. Weighing the entire sprayer only estimates total output, not how that output is spread across the field, so it won’t confirm uniformity.
