I've done it and learned the hard way. The soil has to be rebuilt, it's fertility replaced. A proper transition to organic should be done over a few years with green manure rotations, cover cropping and soil amendments. And there's a lot more to it than manure. Our organic fertilizers cost the same or less than non-organic. I can do a full spectrum nutrient package for $50/acre. Calcium, soft rock phosphate, molasses or sugar, compost tea, and liquid fish. As for organic wheat being half the yield, maybe it was in some fields you saw, but that is not how it is everywhere in every circumstance.
Iowa State study, showing organic corn 20bu/acre behind conventional, and soybean yields equal:

The Rodale Institute has run a 30-year study of side-by-side crop plots with organic vs conventional beans, corn, wheat and other crops. Here's a quote from it:
"Over the 30 years of the trial, organic corn and soybean yields were equivalent to conventional yields in the tilled systems. In wheat yields were the same for organic and conventional systems. (Wheat wasonly added to the conventional system in 2004)."
