The product Vinassa Rompak, resulted in the yeast obtaining technology process, can be a good fertilizer for agricultural crops and a factor for maintaining the balance between the microorganisms populations from the soil. The experiment
regarding the infl uence of fertilization by using the Vinassa Rompak product was made on two permanent growing; a permanent pasturelands and fodder beet. The results presents the infl uence of the fertilization process emphasize a variation of the total number of microorganisms, of the report between the main groups (bacteria and fungi), and of the micromycetes spectrum determined in each
