To be fair, growing stuff in what constitutes "soil" in Las Vegas back yards is kind of hit or miss. As a kid, with my parents help, we eventually managed some decent gardens by building a raised bed and filling that with something the plants could deal with. :-) The point is valid though, it will throw off the Ph quite a bit if you have it mixed in with what is left of the caliche. One of the houses on the block where I had lived refilled the hole, left when the pool contractor threw up their hands, with agricultural fill dirt. They had a very nice yard.
