High doses used in crops accumulate in the soil and plants, hindering the metabolic processes of soil organisms. This study assessed the soil microbial activity in response to the application of K sources in banana crop and effects on microbial C. The experimental design was completely randomized with four K sources: potassium nitrate (KNO.), potassium chloride (KCl), potassium sulfate (K.SO.), and monopotassium phosphate (KH.PO.) at 200 mg kg-1 of K.O, besides the control (without K) and combinations KCl:K.SO.. KCl application increased microbial activity 7 days after incubation, with gradual reduction over time. The isolated application of K.SO. and the combination KCl: K.SO. at the ratio 60: 40% increased total CO. released by the microbiota. K.SO. source had the highest microbial biomass C (MBC), as well as the 60: 40 combinations. Isolated application of K sources, especially with high chloride concentration, reduces the soil microbial activity and MBC. 2022 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187174530021 https://www.redalyc.org/journal/1871/187174530021/ https://www.redalyc.org/journal/1871/187174530021/html/ https://www.redalyc.org/journal/1871/187174530021/187174530021.epub https://www.redalyc.org/journal/1871/187174530021/movil https://doi.org/10.4025/actascibiolsci.v44i1.58248 en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
