Calibrate your spreader to put out what is needed IE: 1 pound per 1,000 sq. feet Example: (for simplicity) take and mark off a 10' wide by 100' long area and put 1 pound of fertilizer in the spreader and adjust the setting accordingly if you run out before you reach the end, or if you have some left over at the end.
