Abstract: The present invention relates to polymeric soil conditioner Absorbency stability as a new water absorbing polymeric material and a process for the production of water absorbing materials consisting of a combination of synthetic polymers and biopolymers, with an improved high water absorbency at repeated watering, capable to reduce the effect of accumulation of salts in polymeric matrix as of multiple cycles of swelling-deswelling that occurs during all period of living of vegetable culture, by decreasing of crosslinking density of three dimensional network of the material caused by biochemical processes that developed in polymeric gels.
