Abstract:
Grassland’s management by low-input might be a viable method for maintaining the high conservative value grassland.
Our goal is to study the effect of organic fertilization and mulching upon the phyto-diversity and productivity of
oligotrophic grasslands in Gârda de Sus commune, Apuseni Mountains. An experimental field with 7 variants in 5
repetitions was founded using the random blocks method, at an altitude of 1320 m, on an Agrostis capillaris with
Festuca rubra grassland type. After organic fertilizers and mulching’s application, there haven’t been noticed any
significant growths of the DM yield in any of the two experimental years. At the sward’s level minimum changes have
been recorded. The grassland type of the witness variant is Agrostis capillaris with Festuca rubra, and through
treatment’s performance, Festuca rubra with Agrostis capillaris type is being installed. Also, the phyto-diversity
slightly changes.
