The Floating System is a cultural technique by which plants are sown on sterile soil contained in floating supports placed in waterproof bowls containing water and nutrients.
The resulting advantages are represented by a reduction in water consumption and the lack of dispersion of fertilized water in the soil as well as the absence of fumigants and chemical residues otherwise present. The product obtained is of excellent hygienic and sanitary quality.
The same advantages are obtained through subirrigation. With this technique, the seedlings, sown in a cube of sterile soil, are placed on a subirrigated mat with nutrients gradually absorbed by the plant. The excess water is not dispersed but is reused for other land-based crops.
