Bigyin, I can only thank you for the explanation and history of your land ! Allthough if I come up with a magic method of stump disposal I will of course inform you. With regard to my land,we did not know it used to be covered with olive trees,until we recently noticed the massive pile of roots behind our neighbours barn !

I was going to add Phil that in case you thought I was an eco terrorist, I planted 92 new olive trees the following year.  Have you thought of doing that ?  Very satisfying and I can give you some pointers if you want.
