Agodzo, S.K. Gowing, John W. Adey, M.A. Trickle irrigation using porous clay pots Trickle irrigation can result in very high water use efficien­cy and is well-adapted to cropping on marginal land but is not an appropriate technology of the majority of small­scale, resource-poor farmers. Simple, low-cost applica­tions of the trickle concept have received little scientific attention. This paper presents summary of an extensive laboratory, field and computer study into such a system based upon the use of porous clay pots. untagged 2018-02-12
