We compared two neighbouring alkaline grasslands from a nature conservation point of view. The two grasslands are situated in different countries, resulting in different land uses. This study characterises the vegetation of the area in focus using the categories of the General National Habitat Classification System (Á-NÉR) and compares the two sides based on naturalness categories, diversity ordering, social behaviour types, differential species

Eriochloa villosa has recently appeared in Romania (CIOCÂRLAN, 2006; FĂRCĂȘESCU et al., 2007). This species has dramatically spread in Banat (S-W) Romania in only two years (2006 and 2007). The most probable mode of propagation of this species in Romania isby infested drop seeds. Measurements of some main morphological parameters showed no differences compared to results published by other authors. Chemical control with Nicosulfuron resulted

A short field experiment (27 days) was carried out in summer 1995, to study the effect of an actively growing grass sward on nitrogen transformations of a pig slurry. The ammonium fraction of the slurry was labelled with (15NH4)2SO4. The slurry was spread manually on microplots in mid-June, at the rate of 3 l/m2, on a cut ryegrass sward, and compared with bare soil. Absorption of 15N-labelled NH4 by the grass occurred very rapidly, attaining 41%
