Generic Spreader Setting Chart

The following chart is meant to provide general guidance when an actual setting is not available.  The age and condition of the spreader may affect the flow of product.  The spreader may need to be calibrated to get proper coverage.

To calibrate your spreader:

  1. Determine the amount of fertilizer needed for 100 square feet.
  2. Divide the number of square feet the bag of fertilizer covers by 100.
  3. Divide the weight of the bag by this number.
  4. The answer is the amount of fertilizer needed to cover 100 square feet.
  5. Place this amount in the spreader.
  6. Mark off a 10-foot by 10-foot area.
  7. Apply using the suggested setting.

For example: 

The fertilizer bag weighs 25 lbs. and covers 5,000 sq. ft.

5,000 divided by 100 = 50

25 lbs. divided by 50 = .5 or 1/2 lb. of product needed to cover 100 sq. ft.

If product runs out before completing the area, decrease the setting.  Mark off another area the same size and repeat the test until the correct application rate is achieved.

If product remains in the spreader, increase the setting.  Mark off another area the same size and repeat the test until the correct application rate is achieved.
