Zhitska N. Ecological properties of the ground litter of the forest biogeocoenosis (for example Cherkassy region)

3. The results of complex analysis and comparisons of litters of the natural and artificial stands biogeocenosis, growing under the conditions of trophicity D with different wetting degrees are presented. Litters, formed by remains of oak (Quercus robur), ash tree (Frаxinus excеlsior), linden tree (Tilia cordata.), hornbeam (Carpinus betulus), maple (Аcer platanoіdes) and Robinia (Robinia pseudoacacia) leaves are analyzed. Their morphology-fractional characteristic is given; the chemical composition of leaf fall and wastes is investigated. Leaf fall-litter rates' calculations of weight dynamics of litter and movement of biogeneous elements are made; on which basis conclusions are carried out about a tendency of the last to accumulation or removals. Turnover rate of each element is defined. Bioelements' weights are calculated which invade with leaf fall. Litters' destruction speed dependence on stand type and moisture conditions is analyzed. Influence features of different types of litters on soil formation are revealed. With this objective their physical and chemical properties, in particular acidity, moisture and bioelement content are studied. Recommendations are elaborated for optimization of forest ecosystem operation, formed under conditions of oak grove vegetation, which are used in Cherkassy region Forest and Hunt Management Department.
