PCT No. PCT/EP96/04981 Sec. 371 Date May 22, 1998 Sec. 102(e) Date May 22, 1998 PCT Filed Nov. 14, 1996 PCT Pub. No. WO97/19585 PCT Pub. Date Jun. 5, 1997Moulded bodies are described which comprise a humus-containing plant substrate consolidated with polyurethane/polyurea, which are obtainable by slurrying a humus-containing plant substrate in water, admixing a liquid NCO prepolymer having a maximum NCO content of 15% by weight which has been produced by the reaction of toluene diisocyanate with a polyether polyol component containing at least one aminopolyether polyol in an amount of 0.5 to 100 mole % with respect to the polyol component, and introducing the mixture thus obtained into a mould and allowing it to solidify. A process for producing these moulded bodies is also described, as is their use as growth media for seedlings in the propagation and raising of plants.
