The results of three years research on the effectiveness of impact of one-time application of wood ash both contaminated and non-contaminated with 137Cs, and their combined introduction of potassium fertilizers to reduce radionuclide transfer from soil to shoots and leaves of some species of trees and wild berry plants in forest ecosystems of Ukrainian Polissia. It has been demonstrated that the introduction of a single application of wood ash both contaminated with 137Cs and non-contaminated combined with potassium fertilizers (50 : 50 on a percentage of potassium) at the rate of 100 kg of potassium to 1 ha reduces the transition of radionuclides from soil to studied plants on average for three years to 35 and 20% respectively. For some types of wild berry plants (young shoots and leaves of blueberries and cranberries) and trees (young shoots and leaves of mountain ash and oak) coefficients of 137Cs transfer during the third (2014) year after applying meliorants decreased by 40–70% compared with plants control split.
