Terrain shading issue

Hello, as you can see from the image my terrain is having some shadow issues. The shadows are on full settings and so is the quality level of unity. The terrain is not unity's terrain it's my own generated in a 100X100 chunk. There are four of these chunks rendered below. The shadows are obviously the issue and iv searched google inside out for a fix. Im in unity 5.0 which the terrain is using the standard shader and using just a diffuse. Is there any way to make the shadows soft or not like this atleast. The terrible shadows only show at certain distances(bad shadows like this or non). I really need shadows to show detail in the terrain and if there isnt a fix is there any solution. I cannot just bake a map because the terrain is going to be editable.
