Abstract

Semi-natural grasslands have a special importance at national, European and even global level. Their maintenance within the agricultural landscape depends on a certain management which is applied on them. Our studies from Apuseni Mountains propose the testing of treatments with combinations of organic and mineral fertilizers application. After treatments, the dry matter harvest significantly increases in all variants’ case, at sward’s level appear important changes that go up to changing the grassland type. Phyto-diversity reduces significantly according to system’s intensifying, even in case of organic fertilizer application alone.
