Summary

Transformation of natural ecosystems through the development of agricultural activities has led to profound changes in the structure of land area involved, often with multiple effects on the environment. In such a complex socio-economic outlook becomes imperative to change the use of natural resources in general, agriculture in particular through sustainable exploitation, which requires multifunctionality, biodiversity, yield stability, environmental compatibility, sustainability of natural resources of soil etc.. Intensive livestock development requires large amounts of feed to ensure quality and proper. Production of forage obtained by exploiting praticoecosystems, is an important activity in the livestock economy. Due to large amplitude value of pasture forage plants, animals consume feed selectively, preferring to start plants more valuable. In most praticoecosystems, especially those operated by grazing, there is a change in floristic composition, often by invading plant species such surfaces devalues their economic value, both quantitatively and qualitatively.

The overall objective of the project relates to the discovery of the mechanisms by which certain harmful plants fail to invade many praticoecosystems Central Moldavian Plateau area and seeking practical solutions to rehabilitate these degraded lands, in particular by improving operations and ensuring optimal conditions the manifestation of natural limiting factors as biological ones, represented by phytophagus of these plants and agents phytopathogenic.
