Utilization of biofertilizers based on the B. megaterium did not increase the number of Bacillus megaterium in the soil, but they were conducive to the stabilization of this strain in the soil environment that is crucial since any pressure affected on the homeostasis of soil environment has an adverse effect [ 50 ]. However, sugar beet plants showed healthy storage root with NS + HS + BA + DSBC +O and NS + HS + BA as well. Senegal Croatia Bolivia Uruguay Kosovo Argentina Lesotho 2014).
