o:7306 PRELIMINARNA ISPITIVANJA POJAVE SUŠENJA U KULTURI PINUS STROBUS NA MEHANIČKI OSTEĆENIM ZEMLJIŠTIMA PRELIMINARY INVESTIGATION OF DIEBACK IN A PINUS STROBUS PLANTATION ON MECHANICALLY DAMAGED SOILS sr The investigation of diback of trees in an eastern white pine plantation on mechanically damaged soils was made on the territory of REIK "Kolubara". 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. 2025-03-21T11:08:42.654Z 44 yes 46 Jelica Popović 46 Nada Veselinović application/pdf 2789112 https://unilib.phaidrabg.rs/o:7306 no yes 1 70 92000001 1988 71A07 Zbornik radova Instituta za šumarstvo 103 110 Institut za šumarstvo 1988
