Abstract The use of products based on humic substances (HS), such as K-humate (KH), and the implementation of soybean seed inoculation technology can provide positive impacts on biological nitrogen fixation (BNF). In this work, different KH concentrations (0, 50, 100, 150, 200 and 4000 mg kH L−1) were applied to soybean seeds inoculated with Bradyrhizobium, and the effects of this compound on Bradyrhizobium seed survival, root morphology, nodulation, biomass increase and nitrogen content were evaluated. KH concentrations of 50, 100 and 4000 mg kH L−1 increased (p
