Checking Fertilizer Rates

To check fertilizer rates:

Tie a 4L (1 gal) container to machine frame next to a fertilizer opener. Remove delivery hose from opener and insert hose into container.

To obtain gal/acre or L/hectare that will actually be delivered:

1. Drive forward at planting speed 244 m (800 ft).

2. Measure fluid (mL or oz) caught in container.

  • Metric Example:

    Liters Per Hectare Conversion Chart
    Row Spacing Conversion Factor
    51 cm 0.081
    76 cm 0.054

     

    Multiply fluid mL caught by the conversion factor for row spacing being planted. See Liters Per Hectare Conversion Chart.

    For this example, 296 mL of fluid was captured in container with 76 cm row spacing.

    296 oz x 0.144 = 42.69 L/hectare

  • Standard Example:

    Gallons Per Acre Conversion Chart
    Row Spacing Conversion Factor
    20 in. 0.255
    30 in. 0.170

     

    Multiply fluid oz caught by the conversion factor for row spacing being planted. See Gallons Per Acre Conversion Chart.

    For this example, 10 oz of fluid was captured in container with 30 in. row spacing.

    10 oz x 0.454 = 4.54 gal/acre
