Am I reading that correctly, 1" is applying over 800# of N and 900# of K? And it's free?
And the second table is doubled but still 1" (typo?, should it be 2"?).
It is free. Even the delivery is free. They can’t get rid of it fast enough.
Its not a perfect answer, nothing is.
One other thing I have noticed is it keeps the top of the ground more moist when it’s dry and it seems to attract more earth worms. I would think this might have an affect of breaking up compacted soil to some extent.
I probably put one large Hagedorn spreader heaped up pretty good per 3/4-1 acre. Can’t imagine there’s more than 15 tons per acre.
75tons/acre would be 5” thick and kill everything.
Corn farmers put down a LOT of it. I’d guess they’re doing 3-4” thick based on visual observation.
In the first picture below, look under the tractor & spreader. That’s about how thick it normally gets applied
