The environmental impact of viticulture: "The influence of the biofertilizer type on wine quality and soil microbiological activity"

Abstract

A trial was conducted in variety/rootstock Merlot/SO 4 in the vineyard district of Jagodina. At the beginning of grapevine vegetation, microbiological fertilizers (A-Az. chroococcum, AH-Az. chroococcum + humate, ABC-Az. chroococcum + Bacill. megaterium + Bacill. circulans, and ABC + H-Az. chroococcum + Bacill. megaterium + Bacill. circulans + humate) were incorporated in the vine row, in the top 20 cm of soil. In 2002, during the rapid growth in spring through blooming, biofertilizers were applied in the root zone of vines. Analyses of the influence of the biofertilizer type on total number of bacteria and input of populations were investigated in the harvest period.
