Abstract

Η παρούσα εφεύρεση αναφέρεται σε μέθοδο παραγωγής στρώματος εγκλείσεως το οποίο βελτιώνει την συγκράτηση νερού και θρεπτικών ουσιών εδαφών, ιδίως αμμωδών εδαφών. Η νέα μέθοδος χαρακτηρίζεται από το ότι εισάγεται εντός του εδάφους ένα στρώμα ορυκτής αργίλου / πήγματος πολυμερούς, κατά τέτοιο τρόπο ώστε η ορυκτή άργιλος να αντιδρά παρουσία νερού, με ένα ή περισσότερα υδατοδιαλυτά πολυμερή ικανά να αντιδρούν με την ορυκτή άργιλο, η ορυκτή άργιλος ενεργοποιείται με αλκαλικό ενεργοποιητικό παράγοντα κατόπιν αντιδράσεως του με το πολυμερές, και εάν επιθυμείται, προστίθενται στο πήγμα, ένα ή περισσότερα υδατοδιαλυτά ξηρά κολλοειδή πήγματα διογκώσεως ικανά για λήψη τουλάχιστον 100% νερού ή/και μία ή περισσότερες χημικές ουσίες για γεωργική χρήση (θρεπτική ουσία φυτών, μυκητοκτόνος ουσία ή ουσία αυξήσεως της αναπτύξεως φυτών, ή/και, εάν επιθυμείται, το πήγμα και τα μη αντιδράσαντα μόρια του πολυμερούς ενώνονται σταυροειδώς με μία αλδεϋδη και τέλος το έτσι σχηματισθέν στρώμα πήγματος καλύπτεται με στρώμα εδάφους.ωThe present invention relates to a method of producing an inclusion layer which improves the retention of water and soil nutrients, especially sandy soils. The new method is characterized by the introduction of a layer of mineral clay / polymer gel into the soil in such a way that the mineral clay reacts in the presence of water, with one or more water-soluble polymers capable of reacting with the mineral clay, the mineral clay being activated by alkaline activating agent upon reaction with the polymer, and if desired, one or more water-soluble dry colloidal swelling gels capable of absorbing at least 100% water and / or one or more chemicals for agricultural use (plant nutrient, fungus) are added to the gel. plant growth-promoting substance or substance, and / or, if desired, the gel and the unreacted polymer molecules are crosslinked with an aldehyde and finally the gel layer thus formed is covered with a soil layer.
