How to make ground like this?

Hi. Found this picture http://paqwak.com/NR03W.jpg and i wonder, how can i do that type of ground in blender so it’ll look realistic. I quess sculpt or displacement, but i tried somethink like that a while ago and it didn’t look good. Thanks.

Particles for the leaves might work - google an Andrew Price tutorial on grass or desert rocks to get an idea on how to use them for landscapes.
