The Effect of Fertilization on Floristic Composition and Biodiversity of Montane Grasslands (HNV) in the Eastern Carpathians.

ABSTRACT: High Nature Value (HNV) mountain grasslands in the Eastern Carpathians are highly sensitive to changes in management intensity, particularly fertilization. This study assessed the effects of contrasting organic and mineral fertilization regimes on floristic composition, vegetation types, and diversity in an oligotrophic Nardus stricta grassland within an experimental framework established in 2021. The analysis is based on vegetation data collected over three consecutive years (2022-2024) from nine treatments, including an unfertilized control, organic fertilization with manure (10-30 t ha^-1 applied in autumn or spring), and mineral fertilization with nitrocalcar (Nitrocalc_20-200 kg ha^-1 calcium ammonium nitrate and Nitrocalc_30-300 kg ha^-1 calcium a
