Evaluation of Chakvi Red Soils and Secondary Phytocoenoses Developed On Them

Abstract

The given work envisages results of physical-chemical parameters of red soils in Chakvi (Adjara A.R., Georgia) and multi-element analysis for the purpose of identification and evaluation of their chemical composition and modern fertility level. Besides, in the given work the present conditions of naturally formed co-societies are reviewed which are resulted from irrational usage of phyto-landscapes of seaside Adjara, their anthropogenic influence and abandoning and neglecting agricultural land plots;  the peculiarities for development of  secondary phytocenoses being formed via mutual participation of aborigine and adventitious species are studied. The research has showed that research soils are acidic; they are poor in general humus and nitrogen. From macro-elements
K, Mg, P are with minimum concentration and Cd, Cr, Hg, Li, Sb, Se, Ti, Tl, V, Pb are beyond the permissible concentration norm. The concentrations of microelements As, Ba, Cu does not exceed MPC. Phyto-cenotic structure is formed in parallel with growth of coniferous plants via gradual introduction of cenotic inter-relations which is differentiated like rows. Formed secondary phytocenosis are characterized with high potential of species of foreign origin (adventitious). At present stage of restoration successive change in serial phytocenosis totally 63 families, 137 breeds, 191 species from which local is 61 and 130 of a foreign origin are described.
