Our endeavor would be no-till.  We would be using a 24 inch x 3/8 inch thick coulter for the fertilizer with high pressure to blast the nutruients to the bottom of the cut.  We would then be using a 7 1/2 inch spacing 1890 seeder with the openers shifted to give us the 5 x 10 paired row spacing.  Any thoughts about this type of setup increasing fertilizer effficency?
