THE IMPROVEMENT OF THE DEGRADED GRASSLANDS THROUGH RADICAL RECOVERY

Fl. Calin

Abstract
Grasslands, through their productions, contribute to the fodder supplies with a forage rich in digestible nutritive substances, well consumed by the ruminants and horses. The grasslands’ functions are complex and they balance multiple ecological, economical and social aspects. The permanent grasslands degraded by the lack of improving measures’ application and by an irrational use present a destroyed vegetal carpet, with a low covering percentage and an improper floristic composition, which conduct to small and low qualitative productions. These grasslands can be improved by radical recovery (plough and seeding a mixture of valuable graminee and leguminous species). By establishing temporary grasslands as a replacement of the degraded permanent ones, we obtained in the southwestern area of Braila County production increases of 25 – 82%. The fodder obtained from the temporary grasslands is high qualitative and can provide the necessary supplies for the fodder base.
