The spreader calibration formula is “amount of fertilizer used- times 1000- divided by the area of the test strip”. If using a rotary spreader: Lets say your spreader makes a 10 ft. wide strip. Now, multiply 10 by the length of the test strip, which is 50ft.
How are spreader settings calculated?
- Divide 100 by the square foot the bag of fertilizer covers.
- Multiply the weight of the bag by this number.
- The answer is the amount of fertilizer needed to cover 100 sq. ft.
- Place this amount in the spreader.
- Mark off a 10 ft. x 10 ft. area.
- Apply using the suggested setting.
How many pounds of fertilizer do I need per square foot?
Two pounds of nitrogen per 1,000 square feet* is recommended, and your fertilizer contains 20% nitrogen. You should apply 10 pounds of the fertilizer per 1,000 square feet (five pounds from the table multiplied by the two pound recommendation).
