Calibrating Your Spreader
1. Divide 100 by the square foot the bag of fertilizer covers
2. Multiply the weight of the bag by this number
3. The answer is the amount of fertilizer needed to cover 100 sq. ft.
4. Place this amount in the spreader
5. Mark off a 10 ft. x 10 ft. area
6. Apply using the suggested setting
Example
If the fertilizer bag weighs 25 lbs. and covers 5,000 square feet:
100 sq. ft.
———— x 25 lbs. = ½ lb.
5,000 sq. ft.
- ½ lb. of product is needed to cover 100 square feet.
Troubleshooting
- If the fertilizer runs out before completing the area, decrease the setting. Mark off another 10’ x 10’ area and repeat the test until the correct application rate is achieved.
- If there is product remaining in the spreader, increase the setting. Mark off another 10’ x 10’ area and repeat the test until the correct application rate is achieved.
