Abstract: An apparatus for providing purified water to row crops is disclosed which comprises a dark plastic lower sheeting layer upon which impaired water can be ponded, and a clear plastic upper sheet which is positioned above the lower layer in the shape of an inverted V by means of a suitable supporting structure. The apparatus is designed to be placed between two row crops in a field in need of irrigation, and irrigation takes place by filling the lower sheeting layer with impaired water which evaporates when solar energy is transmitted onto the lower layer through the clear upper sheet. The evaporated water collects on the underside of the clear plastic sheet and drips downward along the sheet until it contacts the ground in the vicinity of a crop row. In another embodiment of the invention, clear rigid panels can be employed instead of the clear plastic sheet.
