    "data": {
        "note": "Broadcast application rate GPA = 5940 × the per-nozzle flow (GPM) ÷ (ground speed in mph × nozzle spacing in inches); 5940 converts the units for a full-coverage boom. So a 0.4 GPM nozzle at 5 mph on 20-inch spacing lays down about 24 gallons per acre. Drive faster or space the nozzles wider and the rate drops — recheck the real nozzle flow with a catch test, since worn tips over-apply.",
