Wicking bed
http://dbpedia.org/resource/Wicking_bed
Le « wicking bed » (ou culture sur lit à mèche) désigne divers modes de culture de plantes, intégrant un système d'irrigation visant notamment à économiser l'eau (sub-irrigation). Ils reconstituent à très petite échelle (dans une jardinière éventuellement) le principe de l'aquifère, de sa zone insaturée et de sa zone de circulation capillaire verticale de l'eau. Ils sont notamment testés ou utilisés dans les pays ou régions arides, là où l'eau est rare.

A wicking bed is an agricultural irrigation system used in arid countries where water is scarce, devised by Australian inventor Colin Austin. It can be used both in (arid) fields as in containers. Besides use in fields/containers outdoors, it can also be used indoors (i.e. greenhouse). The system is designed to increase food production while using approximately 50% less water than traditional irrigation, by utilizing underground water reservoirs filled with decomposing organic matter and the process of evaporation.

Despite being an irrigation system (which can even be fitted with automated refill capability via rainwater tank and float-valve), it still remains relatively low-tech. There are a number of commercially available wicking bed products including re-cycled plastic wicking "cells" that are reported to reduce water use by up to 80% when compared to above ground irrigation
