PRIMARY AND SECONDARY (NATURAL) PHYTOCENOSIS AND EVALUATION OF THEIR SOIL COVER PRODUCTIVITY LEVEL OF MOUNTAINOUS ADJARA
Abstract
The present Article discusses recent successive processes dynamics in naturally renovated secondary phytocenosis of landslided territories of rich and diverse mountainous Adjara region. The comparative analysis of soil cover productivity level, floristic composition and cenotic structure of secondary phytocenosis and alongside slopes are made for identification of successive serial stage. The researches show that at lifeless substrates of landslided slopes, phytocenotic structure is formed with gradual establishment of cenotic inter-relations between species, in parallel with growing the coniferous plants, which is differentiated in terraces. A certain system of natural renovation is created, soil-creation processes are active. The secondary phytocenosis have developed at traces of chestnut copses, beech forests and oak forests of landslided mixed-leafy forest formations, where these species of plants are not met and the renovation of these species is not noted as well. The formation of secondary natural phytocenosis took quiet short period (30 years) in local natural climatic conditions, at landslided areas but the prospect for development of monoclimax ecosystems (forests before landslide) is less supposable in nearest future. pH of renovated forest soil is transitive from average acidity to weak acidity. The soil is full of movable CaO MgO PO K O 2 5 2 , , , concentrations and is poor in humus and nitrogen. Natural mixed-leafy forest soil reaction is near to natural. The concentrations of movable calcium are 1-2 times more and movable Magnesium 4 times more in it. Besides, general humus concentration is 1,75 % more and general nitrogen is 0,232% more which indicates at high productivity level of these soils. Natural mixed-leafy forest soil is characterised by much higher productivity (area reaction, concentrations of movable forms of nutritious elements, Humus and Nitrogen), rather than pine-forest soil, which makes reflect at special compositions of renovated forest and natural renovations process as well.
