In the near future, it is likely that closed soil-less growing systems will be increasingly adopted in Mediterranean countries because they reduce water and fertiliser use, and appreciably reduce nutrient loss to the environment. However, closed systems increase the salinity of the re-circulating nutrient solution through the progressive accumulation of ions not required by crops and/or applied in excess of crop requirements. Additionally, it is necessary that nutrients be added to the solution according to crop absorption to avoid fluctuations of nutrient ...
