What is the Speedygreen 3000 calibration for Merit granules?

anyone use this Scotts spreader and know the appropriate setting by chance?


We do not know the settin of that spreader for application Merit granules.  However, almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet.  So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting.  You can calibrate this 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. The 60 pounds per acre equates to 1.4 pounds per 1000 square feet.  Or, you can call Bayer, the manufacturer, and they may be able to tell you what setting you should have it on.  You can reach them at (800) 331-2867.
