Abstract: In order to evaluate the effect of fungicides and bioagents on physico-chemical properties of soil under soybean crop, a field experiment was conducted during <em>Kharif</em> season of 2016 at Norman E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. The results showed that the seed treatment through fungicides and bioagents cause non significant change in the soil pH and bulk density while there was significant change in the organic carbon content. Significant increases were also recorded for the available nitrogen and potassium content at harvest. The application of <em>Pseudomonas fluorescens</em> gave maximum amount of available N (275.13 kg/ha) and available K (141.81kg/ha). There was a non-significant numerical increase in available phosphate content which ranged from 20.13 to 26.97 kg/ha. It is concluded that the seed treatment through fungicides predispose the soils to overcome nitrogen, phosphorus and potassium (N, P and K) deficiencies. Among the fungicides and bioagents tested, the stimulation was more pronounced with <em>Pseudomonas</em> followed by formulated Mancozeb
