Before seeding I apply the fertilizer with a 3 point hitch broadcast spreader and work the soil to a powder with a disc and drag. I use a hand/bag spreader at half the seed rate walking end to end and then side to side to increase the odds of getting even coverage. I cover it with a home made cultipacker. That's one reason I don't use seed mixes. You either don't cover the grain seed deep enough or you cover the fine seed so deep it doesn't emerge.
