| Summary: | During this century, increasing effort has been put to the reclamation of eroded areas in Iceland, both in the lowlands along the coast and in the interior of the country. The seeding of grass species along with the application of chemical fertilizers has formed the core of the reclamation work. At least 450 different varieties consisting of about 50 grass species have been tested in variety trials, but only few varieties, all of northern origin, proved valuable. Their performance is strongly dependent on environmental conditions, and it is proposed that a mixture of adapted varieties, subjected to natural selection at each location, would yield belter results. Islannissa on 1900-luvun mittaan panostettu lisääntyvässä määrässä toimenpiteitä erodoituneiden alueiden saattamiseksi uudelleen kasvuston peittoon. Työn perustan on muodostanut eri heinälajien kylväminen ja viljeleminen kemiallisia lannoitteita käyttäen. Kenttäkokeissa on tutkittu vähintään 450 lajiketta noin 50 heinälajista, mutta vain muutamat, pohjoista alkuperää olevat lajikkeet ovat osoittautuneet käyttökelpoisiksi. Lajikkeiden menestyminen on voimakkaasti riippuvainen ympäristöoloista ja onnistuneen tuloksen saavuttamiseksi suositellaan sopeutuneiden lajikkeiden seosviljelyä eri paikoilla vallitsevan luonnonvalinnan alaisena. |
