Abstract

In this study the objective was to determine the effects of mineral and organic – mineral fertilizers on the vegetation cover of a hayfield from the hill area of western Romania, respectively Fibiş (Timiş County). The average of the annual air temperature in this region is 10.7 oC and the average of the annual rainfall amount is 608 mm. The climate in the studied area is temperate continental with Mediterranean influences. The experimental field was organized by setting 6 fertilisation variants (3 mineral and 3 organic – mineral fertilisation variants) and a control non-fertilised variant. Every studied variant had three replicates. The vegetation data were collected using the linear point quadrate method, thus calculating several vegetation features. The vegetation features taken in account were: the botanical composition, the biodiversity (species richness, Shannon and Simpson indexes), some ecological indexes (temperature, humidity, soil reaction and light). The fertilisation influenced mainly the biodiversity and the light and soil reaction ecological spectre.
