I'm trying to create a metal part that carves a wave into a grass floor. I was thinking of cloth and it works great to interact with the floor but it will go back in its initial state once the object passes by. Like in real life the carved earth should stay. any ideas or different approaches on this one?

you may find that softbodies have the advantage over cloth in this. however you can improve matters if you do the following :

In the tag attributes lower the stiffness and flexion ot 0%, up the rubber to 100%, set the size to 100%. under forces tab set the global drag to 100% (and maybe make sure all teh other wind etc is at 0% so it doesn't interfere or add anything to it all). now it should leave a more lasting impression (though i get the feleing that eventually it iwll spring back into shape, but by the time the object leaves the ground you could turn off the cloth tag leaving hte object in this state indefinitely.

How would you go about doing it with soft bodies? In the cloth case I ran into sticking problems. The object goes in the cloth dents it in but when it moves out it drags the dented cloth back out like the cloth sticks on the object.

use the rubber effect to allow the cloth to flow more around the object and reduce the friction too on your cloth. with the softbodies it's a bit more work, you have to set up your cloth object correctly, it's a lot of experimentation to get it right. i've not used the module in a long time so i can't remember the exact settings to use, but i do seem to recall there was a bootprint in mud example in the manual that shoudl get what you want.
