Method of producing a layer of closure to improve retention water and nutrients in soils. Land is introduced in a layer of clay mineral gel / polymer capable of retaining and releasing water reversibly, so is reacted a clay mineral, with 0.5 to 30%, calculated on the weight of the mineral, one or more and water-soluble polymers capable of reacting with aquel mineral; if you want to be a / aden al gel additional amounts of a water-soluble polymer, one or more xerogels dilators insoluble in water, capable of water absorption of 100% at least and forming particle expanded below 1 mm diameter and / or one or more chemicals for agricultural use, preferably a plant nutrient; a fungicidal substance that acts against fungi existing on earth and / or a substance of development enhancer plants, and finally gel coat thus formed is covered with a layer of soil.

SE INTRODUCE EN EL TERRENO UNA CAPA DE GEL DE MINERAL ARCILLOSO/POLIMERO CAPAZ DE RETENER Y LIBERAR AGUA DE MANERA REVERSIBLE, DE MODO QUE SE HAGA REACCIONAR UN MINERAL ARCILLOSO, CON UN 0,5 A UN 30%, CALCULADO RESPECTO AL PESO DE DICHO MINERAL, DE UNO O MAS POLIMEROS SOLUBLES EN AGUA Y CAPACES DE REACCIONAR CON AQUEL MINERAL; SI SE DESEA SE A/ADEN AL GEL CANTIDADES ADICIONALES DE UN POLIMERO SOLUBLE EN AGUA, UNO O MAS XEROGELES DILATADORES INSOLUBLES EN AGUA, CAPACES DE UNA ABSORCION DE AGUA DEL 100% POR LO MENOS Y DE FORMAR PARTICULAS DILATADAS INFERIORES A 1 MM DE DIAMETRO Y/O UNO O MAS PRODUCTOS QUIMICOS PARA USO AGRICOLA, PREFERIBLEMENTE UN NUTRIENTE PARA PLANTAS; UNA SUSTANCIA FUNGICIDA QUE ACTUE CONTRA HONGOS EXISTENTES EN LA TIERRA Y/O UNA SUSTANCIA INCREMENTADORA DEL DESARROLLO DE PLANTAS,Y FINALMENTE LA CAPA DEL GEL ASI FORMADA SE CUBRE CON UNA CAPA DE TIERRA.
