1277: Soil-free farming This paper has been summarised from
‘Soil free farming’ by Callie Seaman and Neil Bricklebank Year
of Publication2011 Hydroponic technologies have the potential to
help meet the increased demand for food, particularly in regions
with limited arable land such as Africa, Asia and parts of
Australasia and the US. Future developments should to
concentrate on energy and water usage; recirculating systems can
be very water-efficient, re-using up to 90% of the water.
Nutrient management is more effective in hydroponic than soil-
based production, in preserving scarce minerals – particularly
phosphate. For the DIY market, hydroponics is likely to remain a
niche part of the broader gardening and 'grow your own' market.
