Abstract: A synthetic culture medium comprising a polymeric material having an apparent density of 0.01 and 0.5 and a specific surface area of between 2 and 25 m2/g, the polymeric material being in the form of an amorphous fibril. Such polymeric materials include thermoplastic polymers such as film-forming linear super polyamides, film-forming polyesters, vinly polymers, acrylonitrile base polymers, and polyolefins, the fibrils being suitable for use as a culture medium either alone or in combination with soil, sand and the like so as to provide a more readily aeratable mixture. Plant growth is improved by a process utilizing such synthetic culture medium.
