Restoration Of An Inactive Quarry By Seeding Herbaceous Species On A Thin Layer Of Fertile Soil

Quarrying is an important activity as it significantly contributes to the economy of a country. This activity presupposes the destruction of the natural vegetation, the removal of the surface soil and deposition of inactive materials. The lack of fertile soil in these disturbed areas is usually a problem for the plant cover establishment. The purpose of this study was to investigate the potential of the establishment of ten herbaceous plant species to inactive quarries with the use of limited amount of fertile soil. The research was conducted in the area of the quarries of the cement manufacture company ?TITAN?, Thessaloniki, Greece. On a terrace of one of the quarries, a 2 cm layer of fertile soil was placed. In early October 2007, the herbaceous species, Lolium rigidum, Festuca arundinacea, Bromus inermis, Agropyrum desertorum, Phalaris aquatica, Dactylis glomerata, Medicago sativa, Medicago lupulina, Sanguisorba minor and Phacelia tanacetifolia, were seeded separately. The first results indicated that among the tested species Dactylis glomerata, Festuca arundinacea and Phacelia tanacetifolia had the highest establishment capability.
