The present invention provides an aqueous artificial mediumncomprising a water-absorbing polymer, which is suitable as a mediumnfor cultivation in soil or hydroponic cultivation of plants. Thatnis, the present invention provides an aqueous artificial medium andna polymer composition, comprising 0.01 to 10 % by weight of anwater-absorbing polymer and 0.001 to 10 % by weight of a cationicnpolymer. Further, the present invention provides an aqueousnartificial medium and a polymer composition, further comprising anporous water-supplying support having a communicating hole. |
