We do not know the setting for that spreader and we are not sure exactly what to set it on. However, almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet. You can calibrate by marking off a 1000 square foot (10 x 100) area and placing 1.4 pounds of any type of product of similar granule size or of the Merit itself in the spreader. Start with a low setting and start walking your marked off area at a normal pace. You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet. You may also contact Scott's directly for help with calibration and recommended settings for your specific application.
