CULTIVATION SYSTEM CHARACTERISED BY SPECIAL SOIL LAYERING AND REUSE OF THE WATERING WATER EXCESS

摘要

Subject: cultivation system characterised by special soil layering and reuse of the watering water excess. Constitution: special soil layering (soil on the top, inflated inert material in the middle and water-and air-proof surface on the bottom having an auxiliary peripheral element meant to retain the excess of watering water; the overflowing water is collected into a cistern, it returns therefrom to the initial watering cistern supplied with water by the irrigation system and finally to the soil for watering this last. Said layering allows the plant to be adapted and partially fed with water in the hydroponic manner (roots being into water); the continuous emptying and filling of the cistern at the field bottom implies the dynamic aeration of the root system which sucks and release incessantly the atmospheric air; the continuous recycling of water with fertiliser diluted therein reduces the fertilization cost. Furthermore, said cultivation system comprises a cistern’s drainage system on the cultivation field bottom and a water discharge system for use when biological cleaning is needed.
