Carpet plant used as temporary grassland is an essential component of forage systems applied in regions lacking natural grasslands (permanent), as is Burnazului plain. It provides the cheapest animal feed during the growing and most balanced in terms of nutrient feed for a period of calves. For quality measurements and analyzes I performed in the dynamic field floristic composition, the vegetation cover density, the permanence, the aesthetic appearance of the vegetation and landscape and I have harvested plant material for laboratory testing and the amount of dry matter content of macro and micronutrients. Based on botanical analysis I found that the mixtures in organic fertilized variants, lucerne reaches a weight of 70-80%. Structure determinations on the vegetative organs of the species yield components shows that both the pure culture of lucerne, and mixtures with Dactilis glomerata variants leaf share increase from cycle 1 to cycle 3-century. Crude fibre content of plants, indicator of consumption and digestion, is very low, 20-28% of dry matter. The lowest values of 20-22%, occurred in pure culture variant lucerne and Trifolium alexandrinum version, fertilized with manure. Microelement content in plants falls within normal parameters.
