I don't know the amount of lime in the phfertilizer, but if you expect 120 lbs of it to raise your soil ph half a point forget it! I believe the thought behind the addition of lime to a fertilizer is to offset the low ph of the fertilizer, not to raise the actual ph of the soil itself. In the 120 lbs you have I doubt that you have more than 40 lbs of lime. So, if you compare that to the recommended 500 lbs you can see that is just a drop in the bucket. But, a 6.0 ph should do OK for clover. You can add some lime at different intervals if taking it all in at once is too much work.
