Abstract

Improved method and apparatus for plant culture, particularly in arid regions. A culture bed is defined by moisture-proof walls and is charged with soil. Pipes disposed at the bottom of the culture bed supply moisture to plants growing therein, the amount of moisture being controlled to maintain the upper boundary of the capillary penetration zone a distance below the soil surface.
