This guide provides straightforward, math-free methods for calibrating different types of agricultural sprayers to ensure accurate chemical application rates. It covers:

• Boom Sprayers: Uses nozzle spacing and timed runs to calculate gallons per acre.
• Backpack & Pump-Up Sprayers: Uses a small test area and timed spraying to determine output.
• Boomless Sprayers: Calculates effective spray width and uses timed collection to find application rate.

Each method emphasizes consistency in spray pressure and speed during calibration.
