Abstract

The invention discloses a method for increasing the water capacity and air capacity of soil matrixes comprising modification of such soil matrixes with a water-absorbing laminate by positioning in the soil a mass of said laminate having a lightly cross-linked polyelectrolyte film with a layer of wicking substrates adhered to both sides of the absorbent film.
