Gatunki i odmiany traw dla celow specjalnych i ich uzytkowanie.

In a field experiment carried out on soil derived from carboniferous wastes, sward growth and development in conditions of different level of utilisation of the following grass species: Festuca ovina cv. Sima, Vitra, Niko; Festuca rubra cv. Nimba, Leo, Jagna, Atra, Areta; Festuca heterophylla cv. Sava; Festuca arundinacea cv. Skarpa and Agrostis capillaris cv. Niwa was assessed. It was found that Nimba, Jagna, Atra, Areta and Sawa cultivars were suitable for following utilisation: pre-sowing application of P+N fertilisers, top-dressing with N and one cutting; while Sima, Vitra and Niko cultivars were well adopted for extensive utilisation - only pre-sowing P+N fertilisation without cutting. Leo and Niwa cultivars died out after two years of utilisation. It was established that Festuca arundinacea cv. Skarpa, Festuca rubra cv. Leo and Agrostis capillaris cv. Niwa were unsuitable for biological reconstruction of soilIs derived from carboniferous rocks.
