Burn or Disc old hay field

Hello folks,

So we are new to the farming world, we have a small hobby farm with a few acres of hay.  The property was not maintained very well so we have tons of weeds in the field.  Trying to grow grass for the cow's and maybe a mule.  So my question is the field is about 7 acres and has clover and milk weed throughout and produces very little grass.  Would you recommend using a disc and reseed, burning the field, or just a fertilizer?  I am thinking just replanting Kentucky 31.

 

Thoughts and thanks in advance.

 

Matt
