SUB-IRRIGATION ON BENCHES (EBB AND FLOOD)
The nutritional solution, after having carefully checked the quality and quantity of the dissolved salts and the acidity, is sent to the benches equipped with an aluminium or polystyrene watertight crop surface (ebb). The solution, after a variable permanence time according to the crops, is drained and send to a proper storage tank. After a filtering and a further salinity control it is sent back to the benches (flood).
