Title
(EN) SOIL CONDITIONING COMPOSITION AND SOIL CONDITIONING METHOD
(FR) COMPOSITION DE CONDITIONNEMENT DE SOLS ET PROCÉDÉ DE CONDITIONNEMENT DE SOLS
Abstract
(EN)
Described is a composition for increasing the water retaining capacity and aeration of soil, comprising a superabsorbent polymer material and xylite fibres having a fibre size of 0.5 - 5 cm. The SAP is preferably capable of absorbing at least 98 w/w% of water with regard to the weight of the superabsorbent polymer material, the absorption resulting in a volume increase of the superabsorbent polymer material corresponding with the volume of the water absorbed, the said superabsorbent polymer material, in an environment having a humidity of 70% or less, releasing at least a portion of the water absorbed therein to the said environment. The xylite fibre material is capable of forming a web structure that retains at least partially the volume increase obtained upon absorption of the water by the superabsorbent polymer material upon release of at least a portion of the water absorbed therein, therewith capable of cavity formation upon water release from the superabsorbent polymer material. Further the use of said composition as soil conditioner and a method for increasing the water retaining capacity and aeration of soil is described.

L'invention concerne une composition destinée à augmenter la capacité de rétention d'eau et l'aération de sols, comprenant un matériau polymère superabsorbant et des fibres de xylite ayant une taille de fibre de 0,5 à 5 cm. Le SAP est de préférence apte à absorber au moins 98 % en poids d'eau par rapport au poids du matériau polymère superabsorbant, l'absorption conduisant à une augmentation de volume du matériau polymère superabsorbant correspondant au volume de l'eau absorbée, ledit matériau polymère superabsorbant, dans un environnement présentant une humidité inférieure ou égale à 70 %, libérant au moins une partie de l'eau qu'il a absorbée dans ledit environnement. Le matériau de fibre de xylite est apte à former une structure en bande qui retient au moins partiellement l'augmentation de volume obtenue lors de l'absorption de l'eau par le matériau polymère superabsorbant lors de la libération d'au moins une partie de l'eau qu'il a absorbée, grâce à quoi il est apte à former une cavité lors de la libération d'eau du matériau polymère superabsorbant. L'invention concerne en outre l'utilisation de ladite composition en tant que conditionneur de sols et un procédé destiné à augmenter la capacité de rétention d'eau et l'aération de sols.
