Wildthing - Thanks for the additional info. I'll check to see if our ag / feed mill has those mixtures. Is it more economical to go the 0-46-0 and 0-0-60 route and fewer bags ??
It really depends on who you buy it from. 0-20-20 is a more commonly stocked fertilizer, then the straight P&K. But it is easier to just fill the spreader up and throw out 1 kind of fertilizer throughout the field, rather then making 2 separate passes to spread 2 different kinds. You could also ask the feed mill to mix them for you, so then it would be easier, but with small quanities and the busy time of year, they may not do it for you. If you were doing a cash crop, that would have been what I would have recommended to do.
