Humic and fulvic substances are organic compounds originating from the decomposition of plant and animal residues in the environment, which can be used as alternative inputs for the management of various crops. The objective of this work was to evaluate the influence of humic and fulvic substances on the chemical and microbiological attributes of the soil in soybean crops. Soil samples were collected at a depth of 0-10 cm before planting and at the flowering stage (R2), and chemical attributes were evaluated, such as macronutrient content, pH and organic matter, and microbiological attributes such as Microbial Biomass Carbon (MBC), Basal Respiration (BR), microbial and metabolic quotient to determine microbial activity. In agronomic parameters, plant development and productivity were evaluated. In the results of chemical attributes, little change was observed between treatments in the concentration of macronutrients; however, an improvement was observed in the concentration of organic matter in areas that received humic and fulvic substances at a dose of 4 L ha-1, a fact also observed in microbiological attributes, with an increase in the microbial community and significant improvement in biological activity of the soil. Data reflected the increase in productivity, with an increase of 10 to 14 bags per hectare, without and with association with Bacillus sp. respectively. It is concluded that humic and fulvic acids at a dose of 4 L ha-1 with or without association with the bacteria Bacillus sp. promoted improvements in the microbiological attributes of the soil and consequently in the development of soybean cultivation.
