boxes are small boxes, generally less than a metre in length and
virtually any water proof box will do. Polystyrene vegetable
boxes work fine and are no or minimal cost while plastics boxes
sold in discount shops only cost a few dollars.
Wicking beds are much
larger than wicking boxes usually made from the numerous types
of raised beds which are commercially available or constructed
from wood or other convenient material. The raised bed is
converted to a wicking bed by lining with polythene sheet and
installing appropriate water pipes and drains. Technically these
are closed wicking beds as the soil is isolated from the ground.
Typically they are less than 10 metres long.
Are similar to closed wicking beds but do
not have side walls, just relying on a bank of earth. They can
be made much larger than the closed wicking beds generally 20 or
They are not quite as efficient water wise
as the close beds as water can escape to the surrounding soils,
the amount is very small and typically deep rooted plants like
fruit trees are grown alongside the beds to make use of the
Wicking furrows are simply a furrow, similar to a conventional
irrigation furrow; they may run down a small incline but are
better placed along a contour. Soil trees, crops or a
combination of both may be grown alongside the furrow.
They are an effective way of improving soil over a large area as
the furrows can be made much longer.
