Here is what I have learned about spreading blends in a spreader:

The SGN of the turf grade we are offering in the blend is actually 220 SGN, not 140 SGN, so it is a bit bigger but not as big as the ag granular which is 320 SGN. So when combined in a spreader, the two blends will tend to separate somewhat because the MAP will spread up to 40 ft while the smaller SOP granule of the turf grade will only spread about 30 ft. The solution is to drive every 20 ft. rather than every 40 ft. & spread twice. It is good stuff, but it won’t spread as uniformly as if it were the ag granular size.

Any further questions on spreading can be taken by Wendell at 507-235-6909, he is a farmer and knows more than I do!
