Build a Soil Sponge That Keeps Roots Watered Between Rains

Instead of delivering water to the surface and hoping gravity distributes it to the roots, this method explains how you can build water-holding capacity deep in the soil profile, below the root zone, where temperature is stable, where evaporation is zero, and where stored water can be delivered upward to roots through capillary action and biological redistribution. The water doesn't fall down to the roots. It rises up to them. From below ... naturally!
