Bacillus velezensis Associated with Organomineral Fertilizer and Reduced Phosphate Doses Improves Soil Microbial—Chemical Properties and Biomass of Sugarcane

Appropriately using phosphorus (P) for the fertilization of sugarcane is critical to achieving high productivity because it one most limiting nutrients in agricultural cropping systems. Thus, objective this research was evaluate morphological, biochemical, and yield responses sugarcane, soil microbial–chemical properties, under use organomineral fertilizer (OF) associated or not with Bacillus velezensis strain UFV 3918 (B) combined mono ammonium phosphate (MAP) doses. The experimental design used completely randomized, consisting eight treatments [Control (3/3 MAP); OF (without + 1/3 MAP; 2/3 3/3 B MAP] four replicates. MAP provided increases accumulated basal respiration (11.9%), carbon microbial biomass (35.9%), fluorescein diacetate (12.7%), arylsulfatase (25.5%), acid phosphatase (10.1%) activity compared control, which implied higher shoot total biomass. These results present a potential strategy fertilization, bacteria combination improve P nutrition growth reduced economic environmental impact.
