Abstract
A channel culture device for agricultural is disclosed. A plurality of elongated reservoir channels are provided adjacent growing channels. The reservoir channels which may be above or within the soil, provide metered amounts of water and nutrients to the growing channels through their walls. An exterior channel is provided which forms the perimeter of a soil bed. The exterior channel includes an inner flexible wall which absorbs the lateral pressure of the soil bed acting on it to prevent buckling of the exterior channel.
