Determining Application Rates
The following procedure provides a means of accurately determining drop spreader settings when settings do not
appear on the package, or to "fine tune" the manufacturer's recommend settings. Spreader rates can vary due to
walking speed, condition of turf, humidity, physical characteristics of the product being applied, or condition of the
spreader. It is good practice to double check settings using the following method
PROCEDURE
The manufacturer will recommend coverages
Step 1:
on the product package. Generally, it is stated as
applying a certain number of pounds of product per
1,000 square feet.
Determine the amount of material in pounds
Step 2:
to cover 100 square feet. Add two zeros to weight of bag
and divide that by the square foot coverage.
To change the decimal portion of answer in
Step 3:
step #2 to ounces, multiply decimal portion by 16.
On a clean walk of driveway, measure out 33.3 feet- the distance required to cover 100 square feet.
Step 4:
Add a measured amount of product to the spreader- 2 to 3 times the recommended rate. Operate spreader
Step 5:
at a brisk walking speed (3 mph of 33.3 feet in 7.5 sec.) over the measured distance. Empty the spreader and weigh
the amount left. Compare with the beginning amount; the difference is the amount applied. Adjust the setting up or
down to achieve the correct application rate.
