Mac,

I commonly mix seed and fertilizer and broadcast them.  To be successful, make sure the seed will make good contact with the soil by having a good seedbed prepared, cultipacking the seed/fertilizer after it is spread, or spreading the mixture just before a rain event.

Another consideration is that commercial fertilizer is very toxic to seed if it is in direct contact.  Don’t allow the seed and fertilizer to be mixed together for an extended period of time.  I like to spread the mixture within four hours of blending to insure the seed is not harmed by the fertilizer.

Growing Deer together,
