Smoothing transition between grass and ground texture.

I finally managed to get my grass looking okay but i’ve encountered a small problem.

I was just wondering if there was a way to make the transition between my grass and my ground material a little smoother (other than the obvious of getting a better ground material). I was thinking maybe base an alpha of the camera distance to blend the two together? Is that the best way to go about it?

Just looking for a second brain on the problem.

You can see the issue here.
