The obtained results have shown: - The intensity of dieback of individual trees and groups of trees is higher, when compared with the 1987 year. - The unsuitable substratum, especiallv bad water-air regime, has a negative influence on microbiological activity of the soil and hence on small return of plant assimilatives. - The pathogenic flngi have an important influence on dieback in eastern white pine plantations, established on substrata unsuitable for growing this tree species on them.
