The article presents the assessment of bioelectroproductivity of wetland sedge ecosystems of Carex acutiformis in situ. It was found that it is possible to obtain a bioelectric potential at the level of 864.2-1114.8 mV, depending on external conditions using a pair of electrodes graphite/zinc-galvanized steel and
graphite/aluminum. The increase in soil moisture had a positive effect on bioelectric potential parameters. Widespread in Polissya biotopes of sedge have prospects as sources of green plant-microbial energy.
