If you put down that much N you will reduce the amount of clover in the mix. I suggest a max of 40# actual N PER application to maintain a mixed stand.
If you want to increase the amount of clover put down the P,K,S,B recommended, but 20# or less of N PER application
Yes that is what I will do-- now looking for a good source of Phosphorus and sulfur-
thanks!
