Mulching represents a profitable technological step in crop production. Beside benefits, vegetal mulching technologies trigger also some phytosanitary risks. This disadvantage can be prevented trough bio-activation of the vegetal mulch by adding antagonistic beneficial bacteria. Three Bacillus strains were selected and used as bio-active agents in vegetal mulch, based on their antifungal properties and biofertilizer activity. The selected strains were analyzed for traits related with plant
