Horse Muck and Newts

Got loads of fantastic horse muck off our next door neighbour today, really well rotted stuff... Found a nice little newt in the pile so had to return it. It was a Smooth newt if your interested. Too late now if you didnt want to know.Am going to sort through every last scrap of muck and remove every bit of root that I can see....it is well rotted though so its not like picking through a big old pile of crap....
