Abstract

Peculiarities of forest bluejoint development are studied according to mean height, surface and underground plant mass on prepared mineralized strips during the vegetation period and over 5 years after soil treatment. Primary successions of blue joint are analyzed according to species amount and its projective cover. A number of regression equations was obtained resulting from statistic simulation of the main growth factors.
