What setting do I use on my Scott easy green broadcast spreader to apply fast acting lime with asp?

We have not tested that spreader at ENCAP. I would suggest starting low (4 or 5), walk a couple of feet, check your progress and make any necessary adjustments. You do not want a thick coverage of lime, you should be able to see the dirt in between the lime prills.

The suggested spreader settings that we provide are based on a test that we performed with spreaders we have at our location. Unfortunately every spreader varies depending on usage and the different materials that have been used in the spreader.
