As I type this (noon lunch), they are spreading 80 acres of it.    They priced it according to commercial P&K + application.    There is 0 N value (it musta got all burned to produce that "clean" electricity up there.    Don't quote me, but I think they are spreading around a half ton to get an analysis of 0-80-60 per acre.   We are putting HRW wheat on this feild within a week.

Benefits......... micronutrients are free.

Con's.......I dunno.........yet.

They are spreading it with a chicken litter spreader, hauling it with a live bottom, and using a conveyor to load, so there is nothing dumped in a pile on the ground.

Maybe I can get some pics?

Good Luck
