Abstract
An underground agricultural irrigation system in which annular semi-cylindrical or concave-convex water reservoirs, formed by splitting used or abandoned vehicle tire casings in half, are buried concave side up at appropriate subsurface depths to trap and retain moisture used to nurture overgrowing plant roots. In a modified version concave moisture retaining caps are mounted over the open centers of each reservoir to increase moisture retention capacity.
