Cover text with dirt

[hotchoclo]

Greetings,

I want to be able to do something, but I just don't know how (here is where you may help!). I have an image of a train rail covered by dirt, more like sepulchered by it. Anyways, I placed some text next to the rail, and want to have the text simulate what's happening to the rail.



In other words, I want to have the bottom end of the text also seem to be covered and buried by dirt.

Any suggestions?

Thanks in advance,

select the areas you want covered, then take that mask over to a dirt area, copy, backup the selction to over lettering again and paste, delete what you don't want
kind of like this?

that's real quick tweak it with a filters
