NE Iowa
I'm in NE Iowa and like to maximize my tonnage per acre with a similar type mix. I like to apply this mix to every acre after both first and third cutting:
85# of DAP (18-46-0)
250# of potash (0-0-60)
15# of Elemental Sulfur
1.5# of actual boron
I shoot for 6.5+ tons per acre per year and this is not much more than removal rates. Hay uses a lot of fertilizer.
