ABSTRACT / SAŽETAK:
The present study analysed interactions between nitrate and nitrite at different soil depths and their effects on pasture vegetation in steppe grasslands. In this case study, four grasslands from western Romania (Voiteg, Gătaia, Partoș, and Rovinița Mică) were analysed. Their nitrate and nitrite content in soil at three depths, the production of fresh forage and the animal load were characterised. At the level of the vegetation sward, the specific contribution of two grasses, two legumes and the noxious weed Ambrosia artemisiifolia was characterised in all the analysed pastures. The nitrate and nitrite data were correlated with the vegetation features mentioned before. The results obtained proved the significant influence of nitrites on the decrease in the rate of Festuca valesiaca L. and the increase in the rate of Ambrosia artemisiifolia L.
