RE: Firm Well-prepared seed bed
I like to disk as level as possible, and cultipack once - then just before the next rain, I broadcast clover seed & fertilizer, And cultipack again.
If the soil is moist its best - maybe even cultipack right after the next rain too, once its not muddy. Because you' re not covering the deed, that cultipacking is what ensures good soil/seed contact - and is extremely important.
