Thanks for this resource Barbara, As a high desert dweller experiencing over 10 years of drought, the thought of a deep well does not have a lot of appeal. My son recently bought a tractor and scraped off all the scrub from an acre and then asked, OK what do we plant? I said nothing until we figure what to do about water. Our contours drain about 3 acres about 20′ from our front door and I have only dammed enough at the property line to prevent cutting a wash through both properties. In fact we had one until I stacked a loose stone wall and then it filled in by itself. I saw a Middle East project by this fellow yesterday, reclaiming 10 acres of desert and it got my attention. This is critical info for desert survival I will pursue.
I would also mention I have been aware of a product for many years that uses water and enzymes to break up those impermeable layers of granite and clay we have, called Nitron. This stuff can create an earthen sponge up to 20 feet deep. If one planted a few crops of alfalfa following treatment, one would have mineral rich grass for composting and mulching so the topsoil would not require turning. It all takes time.
