What term describes adjustments in size, pressure, or other aspects of equipment to improve application accuracy?

• A. Calibration
• B. Maintenance
• C. Inspection
• D. Optimization

Answer: (A)

Calibration is the process of adjusting and validating equipment so its output matches the target application rate and provides uniform coverage. In practice, this means tweaking nozzle size or flow, pump pressure, and even boom height or swath width so that, at the operator’s travel speed, the amount of product being applied per unit area matches the intended rate. Regular calibration helps ensure an acre gets the exact rate prescribed, avoiding under- or over-application due to wear, clogging, or component mismatches.

Maintenance is about keeping parts in good working order to prevent failures, inspection is about checking equipment for wear or damage, and optimization refers to refining overall performance (which can include multiple adjustments) rather than specifically aligning the output to a precise rate. Calibration specifically targets those adjustments to improve application accuracy.
